  • notch filter

Also referred to as a band-stop or band rejection filter; a notch filter is a filter that is designed to screen out a very narrow band of radiation by transmitting most wavelengths with little intensity loss while attenuating light within a narrow and specific wavelength range to a very low level. This range of attenuated light is the stop band. Notch filters are in essence the opposite of a bandpass filter which only transmit light within a narrow wavelength range while rejecting (or attenuating) over most wavelengths.
