Sapphire Round Windows

Sapphire Windows（round）

Sapphire round windows have excellent hardness and strength as protective windows for sensors. They are circular in shape and can withstand greater pressure and stronger vibrations. It has the characteristics of high strength, high hardness, high temperature stability, and corrosion resistance, and can resist the corrosion of various chemical substances. Its applications include wear-resistant components, window materials, and MOCVD epitaxial substrate materials. UM OPTICS can provide different types of window sheets such as circular, rectangular, wedge-shaped, perforated, and stepped sheets.
