Band pass fyuluta imatha kulekanitsa gulu la kuwala kwa monochromatic, njira yabwino yosinthira band-pass fyuluta kudzera pa bandwidth ndi 100%, pomwe band-pass fyuluta yodutsa simalo oyenera. Zosefera zenizeni za band-pass nthawi zambiri zimakhala ndi wavelength yapakati λ0, transmittance T0, theka la m'lifupi la pass band (FWHM, mtunda pakati pa malo awiri pomwe ma transmittance mu bandi yodutsa ndi theka la transmittance pachimake), magawo odulira ndi zina zofunika magawo kufotokoza.
Band-pass fyuluta imagawidwa kukhala yopapatiza-gulu fyuluta ndi burodibandi fyuluta.
Kawirikawiri, bandwidth yopapatiza kwambiri kapena kutsika kwapamwamba kumapangitsa kuti mankhwalawa akhale ovuta kwambiri; pakali pano transmittance pass band ndi kudulidwa-kuzama ndi chizindikiro chotsutsana
Zosefera za band-pass za Wuhan Especial Optics zimapangidwa ndi mulu wa magawo ofanana a dielectric. Kuchuluka kwa zigawo ndi makulidwe amawerengedwa ndikuya kodula kwambiri (nthawi zambiri mpaka OD5 kapena kupitilira apo), kutsetsereka bwino komanso kufalikira kwakukulu (70% narrowband, 90% broadband).
