Optical Filter Glasses & Coated Filter Optics

Optical filters are used to block, transmit, reflect or to cut out a defined light wavelength range. The principle of a filter optic can be dichroic, absorbing or transmitting. They can work as bandpass, short pass, long pass or as attenuation filters. Below you will find a selection of the most popular filters from our extensive filter delivery program. Please follow the links for more details:

Optical filters made from SCHOTT colored glasses

More than 100 different color glass filters for various applications and wavelengths from stock. Our extensive SCHOTT-filter program includes short pass filters, long pass filters, bandpass filters, neutral density filters and color filters as well as conversion filters. more...

 

Neutral Density Filters, Grey Filters, OD-Filters

NG 1, NG 3, NG 4, NG 9, NG 10, NG 11 & NG 12 filters neutrally attenuate incident light with a defined level. more...

 

Heat Reflection Filters (Heat Reflecting Hot Mirrors) SIR Series

Our dielectric heat reflection filter SIR is a coated, dichroic filter. It is transparent to visible light and effectively blocks the infrared band up to approx. 1100nm. more...

 

Heat Reflecting Filters with extended blocking range, SIR-IR Series

The SIR-IR filter features a good transmission in the visible and a broad band blocking of infrared wavelengths. The dichroic filter represents the best possible compromise in terms of maximum blocking range width and high visible transmission. view more...

 

Cold Light Filters, SHD-Series

Our dichroic SHD cold light filter reflects the visible light of a light beam by 45° while it simultaneously lets infrared radiation up to 2500 nm pass at i = 0°. This is the function principle of dichroic beamsplitters. view more...

 

Heat-Absorbing Filters KG1-KG5

Heat-absorbing filters from SCHOTT KG-filter glasses allow the visible wavelength range to pass through and absorb the heat radiation of a light source. Such heat protection filters operate largely independently of the angle of incidence. view more...
