Optical Filters

Coated filter optics and optical glass filters

Optical filters are used to block, transmit, reflect or to filter out a defined light wavelength range in an optical system. The principle of a filter optics can be dichroic, absorbent, reflective or permeable. Such optics can be designed as bandpass, short pass, long pass, notch, damping, or attenuation filters. Optical filter components are mainly found in illumination systems, laser applications, image processing, camera applications, spectroscopy, optical analysis systems, and similar applications. Whether you need colored glass filters, coated filters or custom optical filters, in most cases we can provide a solution for your individual optical task.

Our company manufactures and supplies all types of optical filters for industry, science and research. Below you will find the most popular and constantly available filters for various optical applications from our extensive manufacturing program. Please follow the links for more details and specifications:

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 short pass, long pass, bandpass, neutral density, color filters, as well as conversion filters. This type of filter optics are 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 density level. The filter materials are neutral in color and have a broadband transmission. SCHOTT NG-Filters represent a standard in neutral density filters. more...

 

Heat Reflection Filters (Heat Reflecting Hot Mirrors) SIR Series

Our SIR dielectric heat reflection filters have a dichroic filter coating. It is highly transparent to visible light and effectively blocks the infrared band up to a wavelength of approx. 1100nm. more...

 

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

The SIR-IR filters features a high transmission in the visible and a broadband blocking of infrared wavelengths. This dichroic filter system represents the best possible compromise in terms of 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 infrared radiation up to 2500 nm at i = 0°. This is the function principle of a dichroic beamsplitter. 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. view more...
