A range of SCHOTT optical filter glasses in different shapes and colors

Optical Filter Glass

For more than 135 years, SCHOTT Optical Filter Glass has been known for its high quality, purity and outstanding properties. Offering selective absorption in certain wavelength ranges, our broad portfolio and experience in the field means we can find a bespoke spectral solution for your exact requirements.

Quality, reliability, long-term availability

The products in the SCHOTT Optical Filter Glass portfolio come in all shapes and sizes, but each offer high transmittance, high blocking and no polarization effects. Our experience with different surface qualities and thickness tolerances means we can confidently manufacture complex types of glass, with optical and protective coatings available.

Filter glass portfolio and custom-made components

Filter glass plays a crucial role in a number of applications, such as sensor systems, which depend on filters to operate in the correct range of the electromagnetic spectrum. You can select filters from our standard portfolio or we can provide custom-made solutions to satisfy your requirements. Special coatings or toughened filters are also available.
