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:
We begin with a cinemascope screen. Here we're displaying a 2.35 or 2.40 film, Note the black bars top and bottom. 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. 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.

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.
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.

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. 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: 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 diameterTheta = divergence angleShould 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.
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.
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. 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.
