Detailed Product Description

High Transmittance Calcium Fluoride Infrared Optics Used For Special Optical Windows

 

The calcium fluoride(CaF2) crystal has a high transmittance in the range of 0.13~11.3 um, can reach 95%, with low stress birefringence (no obvious intrinsic birefringence in above 200nm), high refractive index uniformity, mechanical properties are stable, not deliquent, strong resistance to radiation damage etc. CaF2 crystal is an ideal material for making optical components such as optical windows, prisms and lenses.
