Fisheye Lenses

 Typically full frame 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 lens design 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) dslr 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.

Collimating Lenses

 Custom Collimating Lenses for Precise Optical Performance

Hyperion Optics offers economical custom design collimating lenses that can effectively correct spherical and chromatic aberrations, including singlet and chromatic lenses. Many of our clients had experiences where off-the-shelf collimators they purchased for their system do not collimate the light source perfectly, thus affecting the final system performance. To better serve clients with similar challenges when building a cost-effective system, Hyperion Optics provides free design consultation for custom optical collimator in both singlet and chromatic formats.

 

Hyperion's custom collimator lenses help parallelize the entrance light rays into your optical system setup, enabling you to control the field of view, collection efficiency, and spatial resolution. Our existing collimating lens design is responsive at UV-VIS, or VIS-NIR spectrum.

 

Affordable Aspherical Collimator Lenses for Volume Production

Aspherical collimator lens is another hot product that we offer as a cost-effective replacement for volume production. Unfortunately, brand-name aspherical lenses are not the most budget-friendly. Hyperion Optics provides reverse engineering services to help you maintain a competitive edge in the global market, oftentimes with even better system performance since our redesign aimed at optimizing the aspherical lens for your specific application. Please refer to our reverse engineering and aspherical surface production pages for more information.

 

How to Design Your Custom Laser Collimating Lens

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 optics can be assumed so that the beam will be the “clear” aperture of the laser collimating lens. If a fiber is attached to the collimation 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 or singlet collimator lens?

 

For applications such as absolute irradiance, the use of achromatic lenses can offer the maximum benefits. An achromatic lens helps to eliminate the unexpected “contamination” of the spectrum caused by wavelengths outside of the optimal FOV.

 

Further, hyp design offers free consultation on your mechanical design, including lens mount, barrel, and assembly housing. Contact our technical sales team today to find out the best collimating solution for your optical system.

Beam Expander

 beam expansion or reduction is a common application requirement in most labs using lasers or light sources and optics. Users always find there are so many off-the-shelf laser expander, however, hard to find one exactly fit their needs in terms of spectral range or expansion ratio. In most cases, the plug and play solution may not be the answer.

 

Hyperion Optics helps customers with their unique expander development project, from optical design, mechanical design and responsible for the application performance. It is critical to communicate with our engineers your input and output beam diameter ratio requirement. For simple expanders, such as telescopes, consists of two lenses, the magnification of a 2 lens system is equal to the ratio of the focal lengths of the lenses, which is also equal to the ratio of the radii of curvatures of the lenses.

 

M= the magnification of the beam expander

 

F2= effective focal length of exit lens

 

F1= effective focal length of entry lens

 

R2= radius of curvature of exit lens

 

H2=radius of exit spot (image height)

 

H1=radius of entry spot (object height)

 

At Hyperion Optics, we offer rapid optical design and prototyping, in most expander cases, we offer 6 weeks delivery, means when we study your application, expansion ratio and input output parameters, we are able to deliver assembled expander within 6 weeks. Or we can work on your existing off-the-shelf solution to improve your application’s performance.

 

We also offer off-the-shelf expanders, please refer to following products for your requirement, or contact our engineer for further information.
