Izihluzi zamehlo zidla ngokusetyenziswa izihluzo zamehlo, ezizizixhobo ezikhetha ukusasaza ukukhanya kobude obahlukeneyo, ngokuqhelekileyo iglasi ecaba okanye izixhobo zeplastiki kwindlela yokubona, ezidayiwe okanye ezinokuphazamiseka kokutyabeka.Ngokweempawu ze-spectral, yahlulwe ibe yi-pass-band filter kunye ne-cut-off filter;kuhlalutyo lwe-spectral, yahlulwe kwisihluzo sokufunxa kunye nesihluzo sokuphazamiseka.
1. Isithintelo sokucoca senziwe ngokuxuba idayi ezikhethekileyo kwi-resin okanye izinto zeglasi.Ngokokukwazi ukufunxa ukukhanya kobude obuhlukeneyo, kunokudlala umphumo wokucoca.Izihluzi zeglasi ezinemibala zithandwa kakhulu kwimarike, kwaye izibonelelo zazo zizinzo, ukufana, umgangatho olungileyo we-beam, kunye neendleko eziphantsi zokwenziwa, kodwa zinengxaki yokugqithiswa okukhulu, zihlala zingaphantsi kwe-30nm.ye.
2. Izihluzi zokuphazamiseka kweBandpass
Yamkela indlela yokugcoba i-vacuum, kwaye igqoke ifilimu ye-optical kunye nobukhulu obuthile phezu kweglasi.Ngokuqhelekileyo, iqhekeza leglasi lenziwa ngokuphakamisa iileya ezininzi zeefilimu, kwaye umgaqo wokuphazamiseka usetyenziselwa ukuvumela amaza okukhanya kuluhlu oluthile lwe-spectral ukuba ludlule.Kukho iintlobo ezininzi zezihluzi zokuphazamiseka, kwaye iindawo zabo zesicelo nazo zahlukile.Phakathi kwazo, ezona zihluzo zophazamiseko zisetyenziswa kakhulu zizihluzo ze-bandpass, izihluzi ze-cutoff, kunye nezihluzo ze-dichroic.
(1) Izihluzi ze-Bandpass zinokuhambisa kuphela ukukhanya kobude obuthile okanye ibhendi emxinwa, kwaye ukukhanya ngaphandle kwe-passband akukwazi ukudlula.Iimpawu eziphambili ze-optical zohluzo lwe-bandpass zezi: i-wavelength yeziko (CWL) kunye ne-half bandwidth (FWHM).Ngokobungakanani be-bandwidth, yahlulwe ibe: isihluzo esincinci esine-bandwidth<30nm;isihluzo sebroadband esine-bandwidth>60nm.
(2) Isihluzi esisikiweyo sinokwahlula i-spectrum ibe yimimandla emibini, ukukhanya kummandla omnye akukwazi ukudlula kulo mmandla kubizwa ngokuba ngummandla osikiweyo, kwaye ukukhanya komnye ummandla kunokudlula ngokupheleleyo kubizwa ngokuba ngummandla wokudlula, Izihluzo eziqhelekileyo ezisikiweyo zizihluzo ezidlula ixesha elide kunye nezihluzo zendlela emfutshane.Isihluzi se-wavepass yokukhanya kwe-laser: Kuthetha ukuba kuluhlu oluthile lwamaza amaza, indlela eya kumaza amade iyahanjiswa, kwaye umkhombandlela wamaza amafutshane uyanqunyulwa, odlala indima yokwahlula amaza amafutshane.Isihluzi esifutshane se-wave pass filter: Isihluzi esifutshane se-wave wave sibhekisa kuluhlu lwamaza obude obuthile, umkhombandlela omfutshane wamaza uyahanjiswa, kwaye umkhombandlela omde uyanqunyulwa, odlala indima yokwahlula amaza amaza.
3. Isihluzo seDichroic
I-Dichroic filter isebenzisa umgaqo wokuphazamiseka.Iileya zabo zenza uthotho oluqhubekayo lwemingxuma ekhanyayo ehambelana nobude obufunwayo.Xa iincopho kunye nemikhombe zidibana, amanye amaza amaza ayasuswa ngokutshabalalisayo okanye abonakaliswe.Izihluzi ze-Dichroic (ezaziwa nangokuthi "i-reflective" okanye "ifilimu encinci" okanye "ukuphazamisa" izihlungi) zinokwenziwa ngokugquma i-substrate yeglasi kunye noluhlu lwee-optical coatings.Izihluzi zeDichroic ngokubanzi zibonisa iindawo ezingafunekiyo zokukhanya kwaye zisasaze okunye.
Uluhlu lwemibala yohluzo lwe-dichroic lunokulawulwa ngobunzima kunye nomyalelo weengubo.Ngokuqhelekileyo zibiza kakhulu kwaye zibuthathaka kunezihluzo zokufunxa.Zingasetyenziswa kwizixhobo ezifana ne-dichroic prism kwiikhamera ukwahlula imiqadi yokukhanya ibe ngamacandelo emibala eyahlukeneyo.
