Optical filters made from SCHOTT colored filter glasses

More than 100 different high-quality optical color glass filters from SCHOTT for various applications and wavelengths from stock. Our extensive SCHOTT-filter program includes shortpass, longpass, bandpass, neutral- and color filters, as well as conversion filters. This type of filter optics is based on absorption. More...

 

Neutral Density Filters, Grey Filters, Optical Density Filters

NG 1, NG 3, NG 4, NG 9, NG 10, NG 11 & NG 12 SCHOTT-filters attenuate incident light with a defined level. The filter materials are neutral in color and have a broadband transmission. SCHOTT NG-Filters represent a standard for neutral density filters. More...

 

Heat Reflection Filters (Heat Reflecting Hot Mirrors) SIR Series

Our SIR-dielectric heat reflection edge filters have a dichroic filter coating which is highly transparent to visible light and effectively blocks the infrared band up to a wavelength of approx. 1100nm. This filter is often used used to reflect the laser beam in eye-tracking systems while being transparent to the eye. More...

 

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

The SIR-IR filters feature a high transmission in the visible and a broadband blocking of infrared wavelengths. This dichroic filter system represents the best possible compromise regarding maximum blocking bandwidth 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 transmits the infrared band up to 2500 nm at i = 0°. The function principle is that of a dichroic beamsplitter. It can also be used to split visible from infrared lasers. View more...

 

Heat-Absorbing Filters KG1-KG5

Heat-absorbing filters made of SCHOTT KG filter materials allow the transmission of the visible wavelength range and absorb the heat radiation of a light source. Such heat protection filters operate largely independently of the angle of incidence. KG-filters are visible bandpass filters. View more...
