Hauv cov teb uas muaj kev ntsuas siab xws li optoelectronics, thev naus laus zis tso saib, thiab cov cuab yeej siv kho qhov muag, lo lus "optical thin film" feem ntau tshwm sim. Cov txheej txheej no cuam tshuam ncaj qha rau cov cim qhia kev ua tau zoo xws li kev xa tawm, kev cuam tshuam, thiab kev ua xim, thiab thaum kawg ua rau pom kev pom thiab kev ua haujlwm ntawm cov khoom kawg. Tab sis cov yeeb yaj kiab optical thin films yog dab tsi, thiab lawv ua li cas thiaj ua tiav kev tswj lub teeb meej los ntawm cov thev naus laus zis siab heev? Tsab xov xwm no muab kev piav qhia txog kev siv tshuab.
Cov Yeeb Yaj Kiab Optical Thin Films Yog Dab Tsi?
Cov yeeb yaj kiab nyias nyias uas pom tau yog hais txog cov txheej txheej uas muaj qhov tuab txij li nanometers mus txog micrometers, feem ntau yog muab tso rau ntawm iav, yas, lossis hlau siv cov txheej txheem nqus tsev xws li thermal evaporation, magnetron sputtering, lossis electron beam deposition. Cov yeeb yaj kiab no yuav muaj ib txheej lossis ntau txheej sib dhos, txhua txheej muaj cov ntsuas refractive thiab thicknesses sib txawv, tsim los ua kom tiav cov teebmeem pom kev tshwj xeeb.
Cov Ntsiab Cai Tseem Ceeb: Kev Cuam Tshuam thiab Kev Refraction
Lub hauv paus tseem ceeb tom qab cov yeeb yaj kiab nyias nyias yog kev cuam tshuam ntawm qhov muag. Thaum lub teeb ntsib qhov chaw ntawm cov yeeb yaj kiab nyias nyias, nws raug cuam tshuam ib nrab thiab refracted ntawm txhua qhov interface. Vim yog qhov tuab ntawm cov yeeb yaj kiab tswj tau thiab qhov sib txawv ntawm cov ntsuas refractive ntawm cov khaubncaws sab nraud povtseg, cov teeb ci ntsa iab tuaj yeem cuam tshuam lossis rhuav tshem, nyob ntawm lawv qhov sib txawv ntawm theem.
Piv txwv li:
Thaum lub thickness ntawm zaj duab xis raug tsim kom cov nthwv dej reflected tshem tawm ib leeg, cov teebmeem antireflective raug ua tiav - feem ntau siv rau hauv cov iav lens lossis photovoltaic npog iav.
Ntawm qhov tod tes, thaum cov nthwv dej cuam tshuam nyob rau hauv theem, lawv txhawb nqa ib leeg, tsim cov kev cuam tshuam siab lossis cov lim dej xaiv wavelength - raws li pom hauv cov beam splitters, laser iav, lossis optical lim dej.
Qhov kev hloov kho qhov ntev ntawm txoj kev kho qhov muag no yog lub hauv paus ntawm kev tsim cov yeeb yaj kiab nyias, qhov twg qhov tuab feem ntau yog ib feem plaub ntawm lub hom phiaj wavelength (λ / 4) lossis nws cov lej, ua kom muaj kev tswj hwm meej rau cov kab spectral tshwj xeeb.
Cov Hom Phiaj Xwm ntawm Optical Coatings
Cov Txheej Txheem Tiv Thaiv Kev Cuam Tshuam (AR Coatings): Tswj kev cuam tshuam ntawm qhov chaw thiab txhim kho kev xa mus. Siv dav rau cov iav tsom iav, cov koob yees duab optics, thiab cov vaj huam sib luag kov.
Cov Txheej Txheem Muaj Kev Cuam Tshuam Siab (HR Coatings): Ua kom muaj kev cuam tshuam ntau ntxiv ntawm cov wavelengths uas tau tsom mus rau, siv rau hauv cov iav laser, teeb pom kev zoo ntawm theem, thiab cov khoom siv kho qhov muag raug.
Cov Txheej Txheem Lim Pom Kev: Xaiv xa lossis thaiv cov kab ke wavelength tshwj xeeb. Pom muaj nyob rau hauv cov sensors, cov cuab yeej siv kho qhov muag, thiab cov khoom siv sib txuas lus.
Cov Yeeb Yaj Kiab Sib Cais/Polarizing: Cais lub teeb los ntawm qhov ntev ntawm lub teeb lossis lub xeev polarization, siv rau hauv cov zaub, cov projectors, thiab cov zaub taub hau tsheb (HUDs).
Tsim thiab Ua Cov Yeeb Yaj Kiab Optical Thin Films
Cov yeeb yaj kiab nyias nyias uas ua tau zoo tsis yog tsuas yog xav tau kev xaiv cov khoom siv kom raug xwb tab sis kuj xav tau kev tsim cov txheej txheem thiab kev tswj cov txheej txheem zoo heev. Cov thev naus laus zis tso tawm tam sim no suav nrog:
Kev Ua Kom Sov Los Ntawm Thermal
Kev Ua Pa Hluav Taws Xob (E-Beam)
Magnetron Sputtering
Kev Pab Txhawb Nqa Ion (IAD)
Cov txheej txheem no tso cai rau qhov tseeb ntawm nanometer-scale thickness thiab xyuas kom meej cov khoom siv kho qhov muag sib xws thoob plaws cov substrates loj.
Hauv paus ntsiab lus, cov yeeb yaj kiab nyias nyias ua haujlwm los ntawm kev hloov kho qhov kev nthuav dav ntawm lub teeb los ntawm kev cuam tshuam, ua rau muaj kev txhim kho, kev txo qis, kev lim dej, lossis kev tswj hwm polarization. Cov txheej txheem no sib xyaw ua ke cov khoom siv kho qhov muag, cov ntaub ntawv tshawb fawb, thiab kev tso dej nqus tsev rau hauv ib qho thev naus laus zis sib koom ua ke, ua lub luag haujlwm tseem ceeb hauv kev lag luam photonic niaj hnub thiab kev tsim khoom siab. Thaum qhov kev thov loj hlob rau cov txheej txheem kho qhov muag ua tau zoo, qis-kev poob, thiab compact, kev tsim kho tshiab hauv cov thev naus laus zis nyias nyias yuav txuas ntxiv tsav kev nce qib hauv kev lag luam.
