High Durability Sapphire Crystal Optics For Short And Long Wavelength Applications
Sapphire is used for short and long wavelength applications (UV and IR) beyond the range where conventional optics performs adequately. High temperatures and hostile environments also necessitate the use of sapphire optics.
