bandpass filter
A filter that transmits a continuous
range (band) of wavelengths but reflects
or absorbs wavelengths above and below this range. Bandpass filters are
specified by the full width at half maximum (FWHM) of their
transmission peak: wideband (greater than 60 nm FWHM), medium band (20 to
60 nm FWHM), and narrowband (less than 20 nm FWHM). Related
