Bandpass Filter


A bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. IR filters are often used in night vision and IR sensing systems.
