Anamorphic Lenses introduction, to buy from high quality manufacturer
Hyperion Optics specialized in custom anamorphic lenses design and production. We have been customizing unique applications such as projection and anamorphic photography. Generally speaking, these lenses are special tools that affect the aspect ratios and get projected onto the camera sensor.
 
Compared to spherical lenses, which are common and project images onto the sensor without causing aspect ratio change, anamorphic lenses compressing along the longer dimension, which require subsequent stretching, in post-production or at the projector to be properly displayed.
 
With our high quality achromatic cylindrical lenses production capability, we are able to meet the most demanding anamorphic design performance, please refer to our cylindrical lens fabrication capability. To note, in some cases, custom design achromatic cylindrical lenses are extremely thick in CT, we are able to cement singlet parts on real time alignment device to avoid thickness unavailability of certain materials.
 
Here is a great sample that how anamorphic projection lenses can contribute:


anamorphic projection lenses
 
We begin with a cinemascope screen. Here we’re displaying a 2.35 or 2.40 film, Note the black bars top and bottom.
 
 cinemascope screen
 
The first step is to electronically stretch the image vertically. This is either called ‘vertical stretch’ or ‘zoom’ or ‘anamorphic mode’. This feature can be found many projectors and Blu Ray players. We have taken the active illuminated pixels in the black bars and scaled them back into the image. This process increases the overall on screen luminance or brightness. Once vertically stretched, everything on screen looks tall and skinny- compare the image below with the image above.
 
anamorphic mode
 
The final step is the optical expansion of the vertically stretched image to restore the geometry and to fill the entire cinemascope screen with active image. The result here is an image that is 78% larger than the original- Now compare top and bottom images.
 
Highlights of Hyperion Optics’ anamorphic design
 
  • Expected aspect ratio control
  • Sharp image quality, MTF can be tested according to requirement

Structural Design: Introduction to Connection Form of Optical Components

 
 

One:Connection request

In order to ensure that optical instruments are false, some require the quality of light, and the connection between optical components and mechanical is as follows
1) The relative position between the optical parts and the mechanical parts should be accurate. A lens optical system should be used to ensure the accurate distance between lenses and lenses. And as a component made of non-circular optical systems, optical components should be asked of a working face with mechanical components on a point, line, or face the relative position between the right.
2)It is easy to assemble, adjust, and ensure the strong, stable and reliable connection.
3)It will not lead to the distortion of optical components or the production of large internal stresses, which will not alter the performance of optical components.
4)The SS ensures that when the temperature of the environment changes, the internal stresses resulting from the connection and optical components are minimized, which will not affect the performance of the optical components.
5)Cleaning of optical components do not affect the light road and the area of the light.

optical components

Two:The connection of optical components

Round optical components include lenses, splitters, filters, mirrors and protective glass. Common connections for rolling edge, compression ring, elastic press, electroplating, cementing and so on.
1.The connection of rolling edge
The connection of rolling edge is unbroken and the connection structure is shown in figure 13.35. Its structure is simple, compact, light area of effect is very small, but the connection may occur a phenomenon that the tilt and pressure are uneven, aberration goes bad and affect the imaging quality, for larger diameter circular optical components is more serious. As a result, this type of connection structure is usually used for less demanding, smaller sizes.
2.The connection of compression ring
The compression ring connection is detachable. This connection is convenient for assembly and adjustment, if necessary, add elastic space ring, can make the pressure force is uniformly distributed on the optical components, and can reduce the influence of temperature on the compression force. This connection is suitable for the larger, more demanding round optical components.
3. The connection of elastic press
The elastic press connection is removable. The spring card ring is usually only used for optical components that are not high in alignment and solidity. Such as protecting glass and filter glass, the elastic press is used to press the larger optical components.
4. The connection of electroplating, which belongs to the unbroken connection, is used electroplating method to plate copper in the end of the frame, blocking the optical components. The optical components in the electroplating connection are not compressive, only for the connection of small diameter optical components.
5. The connection of cementing
When the copper plated connection is converted to the bonding agent, it becomes the glue joint. There is also no compaction on the optical components.

Three:The connection of non-circular optical components

Non-circular optical components include prisms, reflectors, glass and protective glass. The structural design requirements for non-circular optical components are essentially the same as the circular optical components.

Four:The basic principle of the connecting structure in the instrument:

Hyperion Optics introduces the basic principle of connecting structure in the instrument: 
1)To ensure the strength and accuracy of the instrument
2)To ensure the reliability of the components under use;
3)In order to simplify the structure, it should be possible to use an undetachable connection 
4)Components that need to be adjusted, repaired and replaced should be detachable
5)When there is a number of connections in the part, it is usually necessary to have an undetachable connection for the components or the internal components that are first assembled: the components or the external components that are attached are disassembled
6)Ensure that the components and connections of first and later assembly will not affect each other.
7)Ensure that the components are not deformed or are the least deformed
8) Fewer specifications are better to use connections, don’t use the fine thread connections as possible.
Collimating Lenses

Collimating Lenses


 
Hyperion Optics
Hyperion Optics offers the most affordable custom design collimating lenses, including singlet or chromatic lenses. Customers might find the collimators they purchase for their system do not perfectly collimate the light source they are using to affect the final performance. Hyperion Optics provides a free design for custom collimators, no matter it is a single format or chromatic version which corrects for spherical and chromatic aberrations.
 
Our custom collimators help to make parallel the light enters your setup, allow you to control the field of view, collection efficiency, and spatial resolution. Our existing collimator design is responsive at UV-VIS, or VIS-NIR wavelength.

aspherical collimator lens for sale
 
Hyperion Optics provide laser collimating lens and also provide aspherical collimator lens for your current setup replacement cost wise in volume production. Sometimes it is expensive you order aspherical collimators from famous brand, we can reverse engineer and make it more fordable to maintain your competency in the market, with even better performance since the design is optimized for your application. Please refer to our reverse engineering and aspherical surface production pages for more information.
 
To start with your customized collimating lens design, please verify the expected spot size and focal length of your setup:
 
customized collimating lens design
For a point source, near collimation can be assumed so that the beam will be the “clear” aperture of the lens. If a fiber is attached to the lens, the divergence angle can be calculated depending on the height of the thread. This information allows you to calculate the spot size at a distance.
 
 
  • Tan(Theta) = (Height of fiber)/(Focal Length)
  • Focal Length = Height of fiber = (1/2)*core diameter
  • Theta = divergence angle
 
Should I choose a chromatic collimator or singlet lenses?
 
For applications such as absolute irradiance, benefits the most from the use of achromatic lenses, which helps to eliminate the unexpected “contamination” of the spectrum caused by wavelength outside optimal FOV.
 
Further, Hyperion Optics offers free mechanical design for your setup which including lens mount, barrel, and assembly to fit. Contact our Sales engineers today and find out the best collimating solution for your current setup.
Fisheye Lenses for sale
Fisheye Lenses
 
Typically fisheye lens has a front lens group of a greater negative refractive power than an ordinary inverted telephoto wide angle lens, with a large back focal distance. Its extreme power distribution will cause great field curvature in the transmitted image. As fisheye lens leads to significant barrel shaped distortion, to improve field curvature and astigmatism, it is necessary to compose a doublet to avoid significant negative deviation and provide correction of chromatic aberration.
 
Hyperion Optics designers’ expertise contributes various range of fisheye lenses customized projects, from sminiature fisheye lense used for 360 degree viewing device to 200mm in diameter dome projection fisheye lenses. Our fisheye lens database provides design result and simulations for full frame fisheye lenses, circular image (hemispherical) fisheye lenses with different focal length options.

During design process, our designers evaluate relative illumination performance by utilizing real ray trace analysis, vignetting is also used to control off-axis aberrations due to a half stop or full stop in relative illumination is tolerable in conventional photography scenario. Distortion departure from f-theta mapping is also critical in our design phase, according to the initial simulation and calculation; our designers are able to adjust and optimize to reach an ideal solution. We also look into lateral color which is the lateral shift on the image plane intersection between the shortest wavelength chief ray and the longest wavelength chief ray by real ray trace analysis.
Laser Optics - White Light Laser and its Application
The existing laser technology has always had a short board, which can only emit light of a single wavelength or narrow band. How to expand the frequency of the laser forming ultra broadband, super straight, ultraviolet, visible and infrared wavelengths of coherent white light laser, is still a human unfulfilled dream, it is a worldwide problem of science and technology. This is because the laser optics is composed of optical resonator, gain medium and pump source. The wavelength of the laser is determined by the energy level structure of the atoms, molecules or ions in the gain substance.Because the natural laser crystal material has a great limitation on the gain frequency range and gain bandwidth, the laser can't produce any wavelength of laser.
Will the perfect white laser be created? What changes and developments could it bring to the application of lasers?

1. The sun light

It is known to all that all things grow by the sun, and the sunlight brings light and heat to the earth. The familiar sunlight is a kind of white light, and its spectrum covers ultraviolet - visible - near infrared - mid-infrared bands, as shown in figure 1, In the visible light band (400-700 nm), the radiation energy is strongest, covering seven colors of red, orange, yellow, green and blue, and continuous distribution and transition in the spectrum. Because the sun is white, rainbows are often seen in the sky after rain, or the sunlight passes through a glass prism through seven colors of light (figure 2). This is a common experience in everyday life.

One of the things that people are less familiar with is that sunlight is a completely incoherent light. In terms of spatial coherence, the sunlight cannot be straight and highly divergent. In terms of temporal coherence, there is no phase correlation and locking between different colors of sunlight. So sunlight can only be used to generate energy for heating, water heaters, solar cells and so on.
But the use of modern science and technology, such as the use of sunlight to transmit information, seems to be out of the question.
 
laser
The spectral distribution of sunlight. The spectrum of solar radiation including the sun itself, the spectrum of sunlight entering the earth, and the spectrum of sunlight reaching the sea level due to the absorption of atmospheric water and carbon dioxide. 

2. The advantages and application prospect of white light laser

White light laser light source, short wave laser light sources and continuous laser light compared with the ordinary white light, such as sunlight, incandescent lamp, white LED lamp, etc.), it has the advantages of high brightness, high peak power, wide frequency range etc. In the fields of scientific research, defense military, lighting, communication technology, information technology, industrial production, biomedicine, environmental detection, etc.it got a lot of attention.

White light, as a kind of new laser light source, it has a variety of advantages of good directionality, high energy density, super continuous spectrum, great bandwidth, the center of the flexible wavelength, high degree of coherence time and space. This will greatly expand the function and application scope of laser technology. The white light laser or the solar laser is the completely coherent light, not only the height of the laser beam, but also the very small region. Different color between amplitude and phase locking completely, by regulating the amplitude and phase, it can change the time of laser pulse shape follow one's inclinationsly, and produce very short pulse width (femtosecond and the femtosecond laser pulses. Such a solar laser will have the potential to realize the focus and convergence of light energy in space and time. It releases energy in small areas and very short periods of time to form extremely high instantaneous power density.

The benefits of aspheric lenses
Spherical aberration correction
 
The most significant benefit of a non-spherical lens is that it can be corrected for spherical aberrations. Spherical aberration is caused by using the surface of the sphere to focus or focus on the light. Therefore, in other words, all of the spherical surface, no matter whether there is any measurement error and manufacture error, will appear spherical aberration, as a result, they will need a not spherical or aspherical Lenses surfaces, carries on the correction. By adjusting the constant of the cone and non-spherical coefficients, any non-spherical lens can be optimized to minimize the image difference. For example, see figure 1, which shows a spherical lens with a significant spherical aberration, and a non-spherical lens with almost no spherical difference. The spherical difference in the spherical lens will allow the incoming light to focus at many different points, creating a blurred image. In a non-spherical lens, all the different light rays will focus on the same spot, resulting in less blurred and more quality images.
 
In order to better understand the aspheric lens and spherical lens in terms of focus performance difference, please refer to a quantitative model, in which we can observe two 25 mm diameter equal to the focal length of 25 mm lens (f / 1 lens). The following table compares on the shaft (0 °Angle) and outside the shaft(0.5 °and 1.0 °Angle) in parallel, monochromatic light (wavelength 587.6 nm) generate the light spot size or fuzzy.Spherical lenses are several orders of magnitude larger than non-spherical lenses.
 
The benefits of additional performance
Although the market also has many different techniques for correction by spherical aberration resulting from the surface, however, these other technology in the imaging performance and flexibility, are far less than aspheric lens offer. Another widely used technique involves increasing f / # by "reducing" lenses. While this improves the quality of the image, it also reduces the flux in the system, so there is a trade-off between the two.
 
On the other hand, when using aspheric lens, the additional aberration correction support users in the realization of high flux (low f / #, high numerical aperture) of the system design at the same time, still keep a good image quality. Higher luminous flux design causing image degradation can be sustainable, because a slightly reduced image quality performance will still be provided above the performance of the spherical system can provide. Consider a focal length of 81.5 mm, f / 2 triad lens (figure 2), the first is composed of three spherical surface, the second is one of the first surface of spherical surface (the rest) for spherical surface, the two design have exactly the same type of glass, effective focal length, field, f / #, as well as the overall length of the system. The following table is quantitatively compared with the axis of the modulation transfer function (MTF) at the @ 20% contrast and the parallel, multicolored 486.1 nanometers, 587.6 nm, and 656.3 nm rays. A triad of aspheric surface lens has been used, all on the viewing angle showed higher imaging performance, its high tangential and sagittal high resolution, compared with only the triad of spherical surface lens is three times higher.
 

Glass Precision Aspherical Lenses, IR Aspherical Lenses, Off-Axis Parabolic Mirrors

 
 
 
 
Due to the more complex surface profile of asphere which significantly reduces or eliminate optical aberrations as compared to the simple lens, Aspheric lenses have at least one surface that is not a true sphere,It has been more widely exploited in the lens optical design stage.
 
 
Using aspheres to replace a much more complex multi-element spherical system leads to the result of the optical device can be more compact, lighter, transmit more light and in certain cases be cost effective than the multi-lens spherical design.
 
 
At Hyperion Optics, we are equipped with Optotech asphere machine which offers our customers with contour deterministic micro grinding (CDMG) service, uses the accuracy and repeatability of a computer numerically controlled machine to grind the optical shape.

The Use of Cylindrical Lens
Cylindrical Lens can be used in a single axial convergence or divergence of the beam and found in optical measurement, laser scanning, spectroscopy, laser diode output beam shaping, the X-ray light microscopic imaging, and many other industries and fields have a wide range of applications.

Turn the quasi-direct light source into the line light source
L = 2(r0/f)(z+f)

It is the most extensive application of cylindrical lens. As shown in the figure below, The quasi-direct light source with radius r0 is irradiated into a concave cylindrical lens with a focal length of -f(The image is in order to illustrate the principle more clearly, so amplify the beam radius). The beam will diverge in half theta (theta = r0 / f). At this point, it can also be approximated as the divergence of the point source at the focal point -f. The distance to the back of the lens is z. The width of the line beam is 2r0 (ignoring the divergence of the  Gaussian-distributed beam spot), but the length of the line beam is changed
L = 2 (r0 / f) (z + f)
When z is greater than f, the expansion ratio approaches z/f, and the length of the line is proportional to z.


application of cylindrical lens


If need in the z produces width is very narrow line light source, can be in the plane concave cylindrical lens front end or back end of a flat convex cylindrical lens focal length for z, with the orthogonal plane concave cylindrical lens place, to compress the beam width.

【 Quick Start】The focus and alignment of light

The diode outputs beam of collimation
The laser diode output beam diverges in an asymmetric form, and its quasi-direct work is more challenging. for example, to divergence angle theta. Theta 1 x 2 = 10 ° x 40 ° diode light source, if only use the standard spherical lens, and only in a single direction on collimating, another direction divergence or convergence will happen. Using a cylindrical lens that the problem is decomposed into two one-dimensional directions, through the combination of two orthogonal cylinder lens, two directions can be collimated at the same time.



The selection of the cylindrical lens and the installation of the light road should follow the below rules:
θ1/θ2 = 10°/40° = f1/f2

1)To make the spot symmetrical after the adjustment, the focal length ratio of the two cylindrical lenses is equivalent to the divergence angle.
Theta 1 / theta 2 = 10°/ 40° = f1 / f2

2)The laser diode can be approximated as a point source, to get the collimating output, The spacing between the two cylinders and the light source is equal to the focal length of the two.

3)The spacing between the main planes of the two cylinders should be equal to the difference between the focal length of the f2-f1, and the actual spacing between the two lenses is equal to BFL2 - BFL1. Like the spherical lens, the convex side of a cylindrical mirror should be directed toward a quasi-direct beam to minimize as much as possible.
d1 = 2f1(tan(θ2/2))
d2 = 2f2(tan(θ1/2))

4)Because the laser diode output beam diverges faster, we need to be careful to confirm that the spot size on each cylinder is no longer than the effective light aperture of the lens. Because the distance of the cylinder is equal to its focal length, the maximum spot width of each cylinder should be followed
D1 = 2f1 (theta 2/2)
D2 is equal to 2f2, the tangent of theta one half.

For example, Newport CKX012 (f1 = 12.7 mm, BFL1 = 7.49 mm) and CKX050 (f2 = 50.2 mm, BFL2 = 46.03 mm) the combination of cylinder lens, the spacing between the two lens on the plane for BFL2 - BFL1 = 38.54 mm. The diameter of the spot in the first cylindrical lens is
D1 = 2 (12.7 mm) tan (20 °) = 9.2 mm
The diameter of the light spot in the second cylinder is
D2 = 2 (50.2 mm) tan (5 °) = 8.8 mm

Although there is still a little asymmetry, the simple combinations of these two cylindrical lenses have greatly improved the quality of the beams.

The Application and Development of Cylindrical Lens in Modern Optoelectronic Products
The image monitoring and imaging devices currently being promoted provide us with an irreplaceable safety and comfort...cylindrical lens 
Perhaps, while we are enjoying the convenience of optoelectronic products, we are ignoring the important components of the optoelectronic products, the cylindrical lens.

As we all know, Optoelectronic products are mostly composed of the light path system, electronics and mechanical systems. Light path system is considered to be crucial in the process of information collection and transmission. 

The optical system is composed of lenses, spectroscopes, and reflectors. The surface is usually a sphere or plane. The cylindrical lens is non-spherical, which can effectively reduce the ball difference and color difference. It is divided into flat convex cylindrical lens, flat concave cylindrical lens, double convex cylindrical lens and double concave cylindrical lens. It has one-dimensional amplification. Cylindrical lenses are designed to change the size of the image. For example, turn a spot of light into a patch or change the height of the image without changing the width. The special optical properties of the cylindrical lens make the cylindrical lens more and more widely used with the rapid development of high technology. Such as line gather system. films system. fax machines and printing typesetting scanning imaging system. And in the field of medical gastroscope. Laparoscopic, in the field of auto car video system with the participation of cylindrical lens. Linear detector at the same time in lighting, bar code scanning, holographic lighting, optical information processing, computer, laser emission. And the strong laser system and also has been widely used in synchrotron radiation beam line. At the same time, with the constant improvement of cylindrical lens processing technology, has formed a mature and effective processing technology, the quality of its good reproducibility and repeatability gradually been recognized by the market. At present, the process is gradually replacing the relatively backward traditional technology.

The cylindrical lens is known to consist of a flat and a concave (convex) surface or two concave (convex) surfaces. It can be divided into flat convex cylindrical lens, concave cylindrical lens, double convex cylindrical lens, double concave cylindrical lens, convex concave cylindrical lens. The shape is shown below:


 
The cylindrical lens is a combination of two optical surfaces, and the relative position of two optical surfaces determines the overall optical properties of the cylindrical lens. So how to ensure the rationality of the relative position of two optical surfaces is the key and difficult point in the process of cylindrical lens. What is the ideal relationship between the two optical surfaces? Here is an example of the three views of a flat convex lens.

So in the process of cylindrical lens, if the relative position of two optical surface anomalies, common adverse project has the following kinds: (flat convex cylindrical lens, for example)

One. Bus bad



A: Bus offset: the cylindrical optic surface is offset by the cylinder axis opposite to the flat center. Here is the picture:
Causes and countermeasures:
1.The design or machine of fixture is defective, and the attached surface and the center line are not good. You need to start with the fixture.
2. The lens stick is not in place, need to be attached to the working method to begin to improve.
3. The product moves during processing. Need adhesive adhesion and processing time lens force load begin to improve.

B: Bus tilt: the surface of the cylinder is tilted in a certain angle to the plane. The bus line is not parallel to the attached datum. Here is the picture:


Causes and countermeasures:
1. The design or machine of fixture is defective, the surface of the lens is attached to the axis of the central axis and the failure of the channel is not good. You need to start with the fixture.
2. The lens stick is not in place, need to be attached to the working method to begin to improve.

Two. The bus is perpendicular to the line

Causes and countermeasures:
1. The design or machine of fixture is defective, and the two benchmarks are not straight. You need to start with the fixture.
2. The lens stick is not in place, need to be attached to the working method to begin to improve.
3. The cutting machine is not accurate, and the main shaft and the desktop are in the wrong angle. It is necessary to improve the machining accuracy. In accordance with stated in, cylinder lens bus location plays an important role in the optical performance, then the bus in addition to guarantee in the process of machining, in the test link is also very important. Here's a new way to detect a cylindrical lens:
 
Point laser reflection detector
Principle:
Using a laser generator through a special lens will be test cylinder lens, the light source into cylindrical lens by cylinder after receives the light source the light source is reflected back to image receiver, again by the CCD camera images appear on the display equipment. The final judgment is made by the testers.

Advantages:
High detection accuracy: the detection error can be controlled in 0.001 mm.
High detection efficiency: the skilled person can detect 20PCS per minute.
Do not affect the appearance: using laser reflection to detect has no direct contact to the surface of the product and to the product appearance does not have the effect.
New process of cylindrical lens processing
For a long time, most of the domestic cylindrical mirror manufacturing has been used in the traditional way of processing. It gradually failed to meet customers' needs. Our company is based on many years of lens processing experience, and study abroad advanced processing technology, the development of a set of advanced cylindrical lens to process the new method. This method changes the traditional single chip processing to make the plate processing, greatly improve the processing efficiency, and can reduce the processing cost. The stability of processing quality also increased significantly.
