SCHOTT color glass filters

We keep more than a hundred different high-quality optical filter materials from SCHOTT in stock to ensure fast manufacturing and delivery. The SCHOTT filter program includes shortpass, longpass, bandpass, ND, color, notch, and conversion filters for various wavelengths. This type of optics works based on light absorption.

Neutral Density Filters – Grey Filters – Optical Density Filters

SCHOTT NG neutral density filters are a perfect choice for applications requiring damping of incident light with a defined degree of attenuation. The materials are mainly color neutral and offer broadband transmission. The NG-filter family from SCHOTT includes the NG 1, NG 3, NG 4, NG 9, NG 10, NG 11, and NG 12 materials representing an industry standard for neutral density filters. More details ...

 

Heat Reflection Filters – Heat Reflecting Hot Mirrors – SIR Series

Our SIR dielectric heat-reflection filters have a dichroic thin-film coating, which is highly transparent to visible light and effectively blocks the infrared wavelengths of a light beam up to around 1100 nm. This type of optical short pass filter is also called a hot mirror. The SIR also works in eye-tracking applications to reflect infrared laser beams while remaining transparent to the eye.

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

The SIR-IR filters feature a high optical transmission of the visible and a broadband blocking of the infrared wavelength band. This dichroic hot mirror represents the best possible compromise between maximum IR-blocking bandwidth and high visible transmittance.

Cold Light Filters – SHD-Series

Our dichroic SHD cold light filter efficiently reflects a visible light beam by 90° while simultaneously transmitting the infrared band up to 2500 nm at an incidence of 0°. Hence, it can be called a cold mirror, dichroic filter, longpass, or dichroic beamsplitter. Its dielectric thin-film coating also allows the separation of visible from infrared laser beams.

Heat-Absorbing Filters – SCHOTT KG1-KG5

SCHOTT KG heat-absorbing filters are bandpass filters that transmit the visible wavelength band while simultaneously absorbing the infrared heat radiation of a light source. Such so-called heat protection filters operate almost independently of the incidence angle and are ideal for lighting applications. View details ...
