Product description
Parameters

Zinc selenide has low absorption on infrared wavelength and can transmit visible light. It is the first-choice material to make infrared lens, windows, output coupling mirrors and beam expanders. In high power applications, it is critical to strictly control the absorption and internal defects of the material. Therefore, it not only needs the optical polishing technology that brings minimal damage to the optical components, but also the optical thin film coating of the highest quality is needed. The absorption rate of the material is tested by CO2 laser vacuum heat measurement technology. Our quality assurance department will provide testing according to customer requirements, and carry out certification on the specific optical components. Generally, the polishing diameter of zinc selenide optical components is 5 to 300 mm. According to customer requirements, we can produce optical components within 300 mm in diameter, and less than 25 mm in thickness. Zinc selenide has no hygroscopicity and it has stable chemical properties (unless treated with strong acid).
