Sapphire Step window have a wide transmission band and have good light transmission from UV to IR (0.15-5.5um) with low bubble and inclusion content, so it’s widely used in components, infrared devices, high intensity laser lens material and dome materials, it has high sound speed, high temperature resistance, corrosion resistance, high hardness, high light transmission, high melting point(2045℃) and other characteristic , it’s a very hard to material to processing.
Sapphire windows can resistance of higher temperatures, high pressure, strong vacuum or corrosive environments, because of these features sapphire windows can withstand harsh environmental conditions and provide good performance and reliability, therefore it can be used to make optical components, night vision cameras and other instruments, it can be seen that it has many advantages
