Anti-reflection effect of SiO2 film in sapphire windows

PanRachel 0 Comments

Sapphire windows demonstrate high transmittance in ultraviolet, infrared and visible wavelengths, thus meeting the requirements of multi-mode composite guidance. Additionally, the sapphire light filter exhibits exceptional mechanical properties, chemical stability, and high temperature resistance. It displays excellent performance, including high strength and hardness, which also renders it well-suited for utilization as a wave-transmitting plate.
