Narrow-Band Lim-Subdivided los ntawm Band-Pass Lim
Product Description
Lub ncov transmittance yog hais txog qhov siab tshaj plaws transmittance ntawm bandpass lim hauv passband. Cov kev xav tau rau lub siab tshaj plaws transmittance txawv nyob ntawm daim ntawv thov. Nyob rau hauv qhov yuav tsum tau ntawm lub suab nrov suppression thiab teeb liab loj, yog tias koj them ntau xim rau lub teeb liab loj, koj cia siab tias yuav ua rau kom lub teeb liab zog. Nyob rau hauv cov ntaub ntawv no, koj xav tau ib tug siab siab transmittance. Yog tias koj them nyiaj ntau dua rau kev txwv lub suab nrov, koj cia siab tias yuav tau txais lub teeb liab-rau-suab nrov dua, koj tuaj yeem txo qee qhov kev xav tau ntawm qhov siab tshaj plaws, thiab nce qhov kev txiav tawm qhov tob.
Qhov kev txiav tawm yog hais txog lub wavelength ntau yam uas yuav tsum tau txiav tawm ntxiv rau qhov passband. Rau cov ntxaij lim dej nqaim, muaj ib ntu ntawm kev txiav tawm pem hauv ntej, uas yog, ib feem uas muaj qhov txiav tawm wavelength me dua qhov nruab nrab wavelength, thiab ntu ntu txiav tawm ntev, nrog rau ntu nrog lub cutoff wavelength siab tshaj qhov nruab nrab wavelength. Yog hais tias nws yog subdivided, ob lub cut-off bands yuav tsum tau piav qhia nyias, tab sis feem ntau, qhov kev txiav tawm ntawm lub lim tuaj yeem paub tsuas yog los ntawm kev qhia qhov luv tshaj wavelength thiab qhov ntev wavelength uas lub nqaim-band lim yuav tsum tau txiav. tawm.
Qhov kev txiav tawm qhov tob yog hais txog qhov siab tshaj plaws transmittance uas tso cai rau lub teeb hla mus rau hauv qhov chaw txiav tawm. Cov ntawv thov sib txawv muaj cov kev xav tau sib txawv rau qhov kev txiav tawm qhov tob. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm excitation lub teeb fluorescence, qhov txiav tawm qhov tob feem ntau yuav tsum tau nyob rau hauv qab T.<0.001%. Hauv kev saib xyuas thiab kev txheeb xyuas qhov zoo tib yam, kev txiav tawm qhov tob T<0.5% qee zaum txaus.
