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 collimating the light source they are using to affect the final performance. Hyperion Optics provides free design for custom collimators, no matter it is a singlet 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 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 own 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 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 fiber. 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 into. Contact our Sales engineers today and find out the best collimating solution for your current setup.
