Ang gitawag nga narrow-band filter gibahin gikan sa band-pass filter, ug ang kahulugan niini parehas sa band-pass filter, nga mao, ang filter nagtugot sa optical signal nga moagi sa usa ka piho nga wavelength band, ug motipas gikan sa band-pass filter.Ang mga optical signal sa duha ka kilid gibabagan, ug ang passband sa narrowband filter medyo pig-ot, kasagaran ubos sa 5% sa sentral nga wavelength nga bili.
Ang nag-unang function sa narrow-band filter mao ang pagpasa sa kahayag sa usa ka piho nga wavelength ug mopakita (o attenuate) optical nga mga bahin sa kahayag sa uban nga wavelengths.Ang katunga-nga-wave gilapdon kasagaran kontrolado sa 20nm o ubos pa, ug mahimong gamiton sa ultraviolet, makita nga kahayag, duol-infrared wavelengths, ug layo-infrared bands.Ang makitid nga banda nga mga filter sa among kompanya naporma pinaagi sa taas nga vacuum evaporation sa multi-layer hard films ug ion-assisted deposition sa nanomaterials.Maayo nga pagkakomplikado ug taas nga kahulugan sa imaging.
