Optical Glass Filters
made of SCHOTT Color Filter Glass

Technical color glass filters

Optical color glass filters made of SCHOTT optical filter glass are used for many applications in science and industry. SCHOTT filters Schott filters smallbecame an industrial standard a long time ago and are required for various technical applications and for professional research. Our delivery program of optical glass filters made by processing unpolished raw optical filter glass material, rolled glass sheets or block raw materials, contains all available SCHOTT optical glass filter types. This are more than 60 different types of optical glass filters at your constant disposal. In the following, you will find the basic transmission spectra of all optical glass filter materials.

NEW! Our SCHOTT-Filter Online 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.

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.
