Why Sapphire is an Excellent Choice for Optical Applications?

A synthetic sapphire crystal serves as the sapphire optical window’s substrate (Al2O3). The hardness of synthetic sapphire is second only to that of diamonds. It is a pristine, clear single crystal of Al2O3. Sapphire is a perfect material for high-performance system design and application because of its excellent mechanical, optical, physical, and chemical capabilities.Extreme abrasives like sand and particles can be applied to sapphire lenses without significantly affecting the optics’ clarity. As a result, sapphire optics are the perfect material for many different uses, including aircraft lenses, downhole and drilling vision system optics, inspection windows, watch crystals, and gun sights.
