Optical Substrates made of Glass

Glass substrates made of various glass types

Optical substrates are often used as coating substrates for filters, mirrors and other optics. But also many scientific applications require optical substrates. In many cases, only one side of a substrate must have a high surface quality or flatness, because a substrate usually is not used in transmittance. All of our glass substrates can be polished for special custom surface quality or flatness requirements. They also can be custom coated, provided the quantity is large enough for a custom coating run. We manufacture high quality optical substrates of nearly any suitable glass material that is available on the market. Below, please find a list with links to our respective stock materials:
