SCHOTT Filters

Optical glass filters made of SCHOTT color glass

Color glass filters made of SCHOTT optical filter glass are used for many applications in science and industry. SCHOTT filters became an industrial standard a long time ago. Schott filters smallThey are required for various technical applications and as wellused 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 types from SCHOTT. More than 100 different types of optical glass filters 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.

NEW! Our SCHOTT-Filter Calculator

With immediate effect, our online SCHOTT-filter calculator for the calculation of the transmittance spectra of all available optical glass filters made of SCHOTT color glass filter material, is online and at your disposal. By using our calculator, you can compute custom filter transmission curves. You can choose to analyze the internal transmittance, or the external transmittance which consider the surface reflection losses. You can zoom to a specified wavelength range or view the full transmission spectrum of the filters.
