Optical Bandpass Filter

Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. 

An Optical Bandpass Filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the 254nm and 365nm mercury lines. IR filters are often used in nightvision and IR sensing systems.
