Collimating Lenses

  • Introduction

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:

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.


The collimating lens can transform the optical transmission of an optical fiber into a quasi-direct light (parallel light), or parallel (approximate parallel) light to a single mode fiber.

The design of collimating lens:

The collimating lenses of the reflector and transmission types are used in the beam transmission system to maintain the quasi-straightness of the beam between the laser resonator and the focusing optical element. The reflection type collimating lens is used in a copper full mirror, while the collimating lens of transmission type is used In zinc selenide lens.

Function of collimating lens:

The collimating lens is a common convex lens, where the diverging light enters, and the parallel light emits, and this convex lens acts as a straight line.

Adjustment of collimating lens:

1. The lens (mirror) with the appropriate focal length will be selected according to the required girdle radius of the small divergence Angle. The spot is basically the same size as it needs to be.

2. If the collimation lens refers to the alignment of the light, and adjusts the light path, then the near mirror frame is used to adjust the near field aperture and the far mirror frame is used to adjust the far field aperture. If there is a lens focusing, we should think about the relationship of the near field and far field imaging, otherwise, it will be further off.
