Single Crystal Sapphire window’s optical, electrical, chemical resistance, high thermal conductivity, and mechanical properties make it a superior choice over quartz, alumina and other ceramic materials for hundreds of applications ranging from optical sapphire windows for aerospace sensor systems, chamber windows for semiconductor wafer processing, industrial systems/tools, and even in medical applications.
Frequently it is the combination of two or more properties that make sapphire windows the only material available to solve complex engineering design problems.
