Mamiriro emufirimu akaonda firimu anosanganisira maitiro e optical properties, optical parameters uye non-optical properties, iyo optical properties inonyanya kureva spectral reflectance, transmittance uye optical kurasikirwa (absorption loss uye reflection loss) zvimiro zveoptical thin film. Transmittance uye kutarisisa ndiwo akanyanya kukosha optical zvimiro zveoptical matete mafirimu, saka kuyedzwa kweiyo yakatetepa firimu transmittance uye kuratidza ndiyo yekutanga nzira yekuyedza yemafirimu matete. Optical parameters ye optical nhete firimu inosanganisira refractive index, absorption coefficient uye firimu ukobvu hweoptical nhete firimu. Nekuda kwekutsauka kwe stoichiometric muzvikamu zveiyo optical yakaonda firimu yakagadzirwa nemaitiro chaiwo, chimiro hachichina homogeneous uye dense, asi kune microstructures uye zvikanganiso zvakasiyana-siyana, iyo dielectric film layer haisati yanyatsojeka, uye kune kusimba kunyura, nepo kune nzvimbo isiri-uniformity muchikamu chemufirimu, uye indekisi ichiri kushanda. isingaperi uye yakatsetseka interface. Zvinotonyanya kukosha, mugadziriro chaiyo yekugadzirira, magadzirirwo ekugadzirisa firimu ane simba guru pane optical parameters yefirimu, saka iyo chaiyo-nguva kusimbiswa kweiyo optical parameters yefirimu inonyanya kukosha. Uye zvakare, iyo optical yakaonda firimu sechinhu chinoshandiswa munzvimbo chaimo, kunze kweiyo optical maitiro echishandiso chinoda kusangana nezvinodiwa, iyo firimu kune akawanda akawanda akakosha asiri e-optical maitiro anokanganisa kushandiswa kwefirimu, senge firimu adhesion, kushushikana kwefirimu, kuomarara kwefirimu uye kuoma kwepasi uye kugona kwefirimu kutsungirira zvakatipoteredza zvichingodaro. Naizvozvo, zvakakosha kuyera nemazvo ese akasiyana ma paramita kana maitiro anokanganisa kushandiswa kwemaonda emafirimu michina.
Transmittance uye kuratidzwa kwemafirimu matete anonyanya kuyedzwa uchishandisa spectral bvunzo analyzer. Spectral analyzers yeOptical film test inogona kukamurwa kuita UV-Vis spectrophotometers, infrared spectrophotometers uye infrared Fourier spectrometers zvinoenderana nemabhendi ebvunzo akasiyana. Iwo maviri ekutanga anoshandisa spectral spectroscopy nheyo yekuongorora uye yekuongorora system, iyo yekupedzisira yakavakirwa pamusimboti wekukanganisa spectral analysis system. Nekuda kweakasiyana maumbirwo ejometri uye maumbirwo emidziyo yakatetepa-firimu, kunyangwe ese ekufambisa uye kuyerwa kwezviyero, asi kune akasiyana maumbirwo, kurongeka kwakasiyana kana akasiyana polarization zvinodiwa, zvingada nzira dzakasiyana dzekuyedza uye hunyanzvi.
