Izihlungi zamehlo zivame ukusetshenziswa izihlungi ezibonakalayo, okungamadivayisi adlulisa ngokukhetha ukukhanya kwamaza ahlukene ahlukene, ngokuvamile ingilazi eyisicaba noma imishini yepulasitiki esendleleni yokubona, edayiwe noma enezimbotshana eziphazamisayo.Ngokwezici ze-spectral, ihlukaniswe isihlungi se-pass-band nesihlungi esinqunyiwe;ekuhlaziyweni kwe-spectral, ihlukaniswe isihlungi sokumunca nesihlungi sokuphazamiseka.
1. Isihlungi se-Barrier senziwa ngokuxuba odayi abakhethekile ku-resin noma izinto zengilazi.Ngokuvumelana nekhono lokumunca ukukhanya kwamaza ahlukene, ingadlala umphumela wokuhlunga.Izihlungi zengilazi ezinombala zithandwa kakhulu emakethe, futhi izinzuzo zazo ukuzinza, ukufana, ikhwalithi enhle ye-beam, nezindleko eziphansi zokukhiqiza, kodwa zinobubi be-passband enkulu, ngokuvamile engaphansi kuka-30nm.kwe.
2. Izihlungi zokuphazanyiswa kwe-bandpass
Yamukela indlela yokugcoba i-vacuum, futhi igqoke ungqimba lwefilimu ye-optical enobukhulu obuthile ebusweni bengilazi.Ngokuvamile, ucezu lwengilazi lwenziwa ngokuphakamisa izingqimba eziningi zamafilimu, futhi isimiso sokuphazanyiswa sisetshenziselwa ukuvumela amaza okukhanya kububanzi obuthile bokubuka ukuba adlule.Kunezinhlobo eziningi zezihlungi zokuphazanyiswa, futhi izinkambu zabo zohlelo lokusebenza nazo zihlukile.Phakathi kwazo, izihlungi zokuphazanyiswa ezisetshenziswa kakhulu izihlungi ze-bandpass, izihlungi ze-cutoff, nezihlungi ze-dichroic.
(1) Izihlungi ze-Bandpass zingadlulisela kuphela ukukhanya kobude obuthile begagasi noma ibhande elincane, futhi ukukhanya okungaphandle kwebhande lokudlula akukwazi ukudlula.Izinkomba zokubona eziyinhloko zesihlungi se-bandpass yilezi: i-centre wavelength (CWL) ne-half bandwidth (FWHM).Ngokusho kobukhulu bomkhawulokudonsa, ihlukaniswe yaba: isihlungi se-narrowband esinomkhawulokudonsa<30nm;isihlungi se-broadband esinomkhawulokudonsa>60nm.
(2) Isihlungi esisikiwe singahlukanisa i-spectrum sibe izifunda ezimbili, ukukhanya endaweni eyodwa akukwazi ukudlula kulesi sifunda kubizwa ngokuthi isifunda esinqamuliwe, futhi ukukhanya kwesinye isifunda kungadlula ngokugcwele kubizwa ngokuthi isifunda sebhande lokudlula, Izihlungi ezisikiwe ezijwayelekile izihlungi zephasi ende nezihlungi ze-short-pass.Isihlungi se-wavepass yokukhanya kwe-laser: Kusho ukuthi ebangeni elithile le-wavelength, isiqondiso segagasi elide siyadluliselwa, futhi i-short-wave direction iyanqanyulwa, edlala indima yokuhlukanisa i-short-wave.Isihlungi se-wave pass esifushane: Isihlungi se-wave pass esifushane sibhekisela ebangeni elithile le-wavelength, isiqondiso segagasi elifushane siyadluliselwa, futhi isiqondiso segagasi elide siyanqanyulwa, esidlala indima yokuhlukanisa igagasi elide.
3. Isihlungi se-Dichroic
Isihlungi se-Dichroic sisebenzisa isimiso sokuphazanyiswa.Izendlalelo zazo zakha uchungechunge oluqhubekayo lwezimbotshana ezikhanyayo ezihambisana nobude obufunekayo.Uma iziqongo nemigodi kugqagqana, amanye amaza obude asuswa ngendlela elimazayo noma abonakale.Izihlungi ze-Dichroic (ezikwaziwa nangokuthi "i-reflective" noma "ifilimu elizacile" noma izihlungi "zokuphazamisa") zingakhiwa ngokumboza i-substrate yengilazi ngochungechunge lwezingubo zokukhanya.Izihlungi ze-Dichroic ngokuvamile zibonisa izingxenye ezingadingeki zokukhanya futhi zidlulisele okunye.
Uhlu lwemibala yezihlungi ze-dichroic lungalawulwa ubukhulu nokuhleleka kwezingubo.Ngokuvamile abiza kakhulu futhi athambile kunezihlungi zokumunca.Angasetshenziswa kumadivayisi afana nama-dichroic prism kumakhamera ukuze ahlukanise imishayo yokukhanya ibe izingxenye zemibala ehlukene.
