Narrow-Band Sefa-Yakakamurwa Kubva Mubhendi-Pass Sefa
Product Description
Iyo peak transmittance inoreva iyo yakanyanya kutapurirana yebhendi sefa mupassband. Zvinodiwa zvepeak transmittance zvinosiyana zvichienderana nekushandisa. Mune zvinodiwa zvekudzvinyirira ruzha uye saizi yechiratidzo, kana iwe ukabhadhara zvakanyanya kuhukuru hwechiratidzo, unotarisira kuwedzera simba rechiratidzo. Mune ino kesi, iwe unoda yakakwira peak transmittance. Kana iwe ukanyanya kutarisisa kudzvinyirira ruzha, iwe unotarisira kuwana yakakwira chiratidzo-kune-ruzha Ratio, unogona kuderedza zvimwe peak transmittance zvinodiwa, uye kuwedzera kudzika-kudzika zvinodiwa.
Mutsara wekuchekwa (cut-off range) unoreva huwandu hwewavelength hunoda kuchekwa-chekwa kuwedzera kubhendi. Kune ma filters e narrowband, pane chikamu chemberi cutoff, kureva, chikamu chine cutoff wavelength diki pane yepakati wavelength, uye yakareba cutoff chikamu, ine chikamu chine cutoff wavelength yakakwirira kupfuura yepakati wavelength. Kana yakakamurwa, mabhendi maviri akachekwa anofanirwa kutsanangurwa akaparadzana, asi kazhinji, iyo yakachekwa-yekusiyana yesefa inogona kuzivikanwa chete nekutsanangura ipfupi wavelength uye kureba kwewavelength iyo yakatetepa-bhendi sefa inoda kucheka. off.
Kudzika-kudzika kunoreva iyo yakanyanya transmittance inobvumira mwenje kuti ipfuure munzvimbo yakachekwa. Akasiyana masisitimu ekushandisa ane zvakasiyana zvinodiwa pakudzika-kudzika. Semuyenzaniso, kana ari excitation light fluorescence, iyo yekucheka-kudzika kudzika kunowanzo kudiwa kuve pazasi T.<0.001%. Mune akajairwa ekutarisa uye ekuzivikanwa masisitimu, iyo yakachekwa-kudzika kudzika T<0.5% dzimwe nguva yakakwana.
