Plano sapphire device viewing window by customized rectangle 193x60x7mmt sapphire window lens ＆Sapphire optical Windows Manufacturers.High transmittance 99% at 635nm after coating 1/4lambda flatness dia50/dia60/dia100mm sapphire optical lens;Wearable Anti-High temperature high strength High transmittance Infrared sapphire optical window lens
Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. Sapphire optical windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. It is also resistant to UV radiation darkening.
Optical windows are applied for protecting fragile optical components inside an equipment or directly used for watching windows because of its very good physical property.
they are adopted to isolate two physical environments while allowing light to pass. Optical Sapphire windows refer to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel.
