Collimation Optics : 38mm Series

In optics, a collimator may consist of a curved mirror or lens with some type of light source and/or an image at its focus. This can be used to replicate a target at infinity without parallax. Optical collimators can be used to calibrate other optical devices, to check if all elements are aligned on the optical axis, to set elements at proper focus, or to align two or more devices such as binoculars and gun barrels/gunsights. A surveying camera may be collimated by setting its fiduciary markers so that they define the principal point, as in photogrammetry.

Collimators may be used with laser diodes and CO2 cutting lasers. Proper collimation of a laser source with long enough coherence length can be verified with a shearing interferometer.

Thermal Lensing Compensation(TLC) Optics

Thermal Lensing Compensation TLC OpticsThe TLC (Thermal Lensing Compensation) patent pending (USPTO 12/756,642) optic design passively compensates thermal lensing for high power collimators and focusing lenses. Through the use of special optical materials and optic design, thermal lensing for lasers with powers in excess of 1KW is reduced to less than the Rayleigh range of the lens design.

The Haas Laser Technologies TLC Objective™ incorporate a balancing of the dn/dT between two high power laser optical materials, the thicknesses, air spacing and curvatures to minimize the thermal lensing between 20°C and 250°C using a proprietary optical design merit function. This means your application will be in focus from the moment the laser is first turned on to when it is turned off.

  • For use up to 20KW.
  • Available in 25mm, 38mm and 50mm diameter optic sets.
  • No thermal stabilization time needed.
  • Custom configurations available.
