Sapphire Step Window

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
