Band pass filter inogona kupatsanura bhendi remonochromatic mwenje, iyo yakanakisa transmittance yebhendi-pass sefa kuburikidza nebandwidth i100%, nepo iyo chaiyo bhendi-pass sefa pass bhendi isiri iyo yakakodzera sikweya. Iyo chaiyo bhendi-pass sefa kazhinji ine yepakati wavelength λ0, transmittance T0, hafu yehupamhi yepasi bhendi (FWHM, chinhambwe pakati pezvinzvimbo zviviri uko kufambiswa mubhendi rekupfuura iri hafu yepamusoro yekufambisa), iyo cutoff siyana uye zvimwe zvakakosha parameters kutsanangura.
Band-pass sefa yakakamurwa kuita nhete-bhendi sefa uye Broadband sefa.
Muzhinji, bandwidth yakatetepa kwazvo kana kukwira-kureba kwakadzika kuchaita kuti chigadzirwa chiomerwe kugadzira; Zvichakadaro iyo pass band transmittance uye yakachekwa-kudzika kudzika zvakare chiratidzo chinopokana
Wuhan Especial Optics 'bhendi-pass mafirita anoumbwa nestack yakaenzana yakaenzana dielectric layer. Huwandu hwematanho uye ukobvu hunoverengerwa nekudzika kwakanakisa kwekucheka-kudzika (kazhinji kusvika kuOD5 kana kupfuura), kukwira kuri nani uye kutenderera kwepamusoro (70% narrowband, 90% Broadband).
