Sapphire Windows（rectangular）

Sapphire rectangular windows are protective windows for sensors with excellent hardness and strength. They are rectangular in shape and can withstand greater pressure and stronger vibrations. It has the characteristics of high strength, high hardness, high temperature stability, corrosion resistance, and can resist the corrosion of various chemical substances. The main 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.
