Znse Plano Convex Lens CO2 Laser Output Lens Zinc Selenide Collimation Lens

Product Description

Product Description Zinc selenide is similar in many ways to zinc sulfide. Its refractive index is slightly higher than that of zinc sulfide, and its structure is not as strong as that of zinc sulfide. Therefore, for environmental durability reasons, a thin layer of zinc sulfide is sometimes deposited onto a thick zinc selenide substrate. Compared with zinc sulfide, the most significant advantage of zinc selenide is its extremely small absorption coefficient, so zinc selenide is often used in high-energy CO2 laser systems.
