CVD ZnSe Anamorphic Prisms

Zinc Sulphide (ZnS) is a widely used IR transmitting material in windows, lenses and prisms. The material transmits at about 50% between 0.4 -12μm before dropping off to zero transmission around 15μm. Its low absorbance in the IR spectrum makes it desirable for CO2 lasers operating at 10.6μm. Zinc Sulphide has a pale yellow to clear appearance and a hardness of HK160. Although the material is resistant to thermal shock, it is not recommended for harsh environments.

Lasers usually feature an elliptical beam profile. While, mostly a circular beam shape is required, like mode-matching to an external resonator, adapting beam size to pass a small aperture of an isolator, and etc. Anamorphic Prism Pairs are used to transform elliptical laser diode beams into nearly circular beams by magnifying the elliptical beam in one dimension.
