SCHOTT Filters

Optical glass filters made of SCHOTT color glass

Color glass filters made of SCHOTT optical filter glass are used as optics for many applications in science and industry. The filters became an industrial standard a long time ago. Schott filter optics smallSCHOTT filters are required for various technical applications and are as well used in science and research. Our delivery program of optical glass filters which we make by processing unpolished filter glass material, rolled filter glass sheets, or block glass materials contains all available optical glass filter materials from SCHOTT. More than 100 different types of high quality optical glass filters for various applications therefore are at your constant disposal. In the following you will find the basic transmission spectra of most of these optical glass filter materials.

Our large assortment contains the following SCHOTT filter types:

The color glass filter types marked with an asterix (*) have been discontinued. New serial products should not be based on these glass filter materials unless there is a very high volume demand. It is possible that we have some remaining stock of these discontinued optical glass filter materials though. Please send us your inquiry in such cases.
