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.
Sapphire optics are the preferred transparent material for high-pressure vessels, deep sea windows, and sight glasses, as sapphire lenses and prisms can withstand pressure unlike any other transparent substance and has remarkable thermal and chemical properties.
Sapphire optical windows are excellent choices for applications involving high pressure, vacuum, or corrosive environments. In difficult situations, sapphire windows will outperform all other optical materials and offer a stronger defence against the elements. Sapphire is also used for medical and dental tools in which UV sterilization and curing and IR thermal processing is required.
Many reputed optics specialise in creating a variety of sapphire optical windows. These optical windows feature high-precision polished surfaces, surface accuracy and parallelism. One can choose from an array of sapphire windows, lenses, prisms and blanks. They offer both standard and custom-made solutions to suit individual specifications. One can choose from random polarisation sapphire for any application other than UV, or C-cut or Z-cut for UV applications.
