TLC optics incorporates a balancing of the dn/dT between two high power laser optical materials. Using a proprietary optical design merit function, thicknesses, air spacing and curvatures are optimised to minimise thermal lensing between 20°C and 250°C.
Using TLC optics will eliminate the need to wait for minutes for a system to become thermally stable. The laser will be in focus from the moment it is turned on.
