Peb cov khoom

Band pass lim tuaj yeem cais ib pawg ntawm lub teeb monochromatic, qhov zoo tshaj plaws kev xa tawm ntawm band-pass lim los ntawm bandwidth yog 100%, thaum qhov tseeb band-pass lim dhau band tsis yog qhov zoo tagnrho square. Qhov tseeb band-pass lim feem ntau muaj qhov nruab nrab wavelength λ0, transmittance T0, ib nrab dav ntawm qhov hla band (FWHM, qhov kev ncua deb ntawm ob txoj haujlwm uas qhov kev xa tawm hauv qhov hla band yog ib nrab ntawm qhov siab tshaj transmittance), qhov kev txiav tawm thiab lwm yam tseem ceeb parameter piav.
Band-pass lim tau muab faib ua nqaim-band lim thiab broadband lim.
Nyob rau hauv dav dav, ib tug nqaim bandwidth los yog siab txiav-tawm steepness yuav ua rau cov khoom nyuaj rau txheej txheem; Meanwhile lub pass band transmittance thiab txiav-off qhov tob kuj yog ib tug contradictory qhia
Wuhan Especial Optics 'band-pass lim yog tsim los ntawm ib pawg ntawm qhov sib npaug ntawm qhov sib npaug dielectric txheej. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab tuab yog suav nrog kev txiav tawm qhov tob (feem ntau txog li OD5 lossis siab dua), kev sib tw zoo dua thiab kev xa tawm siab (70% nqaim band, 90% broadband).
