Kutsanangurwa kwefirimu rakatetepa re optical kunosanganisira kutsanangurwa kwehunhu hwe optical, ma optical parameters uye hunhu husiri hwe optical, hunhu hwe optical hunonyanya kureva hunhu hwe spectral reflectance, transmittance uye optical loss (absorption loss and reflection loss) hwefirimu rakatetepa re optical. Transmittance uye reflection ndizvo hunhu hwe optical hwakakosha hwema optical thin films, saka kuyedzwa kwe transmittance uye reflection yefirimu rakatetepa ndiyo nzira yekutanga yekuedza ma optical thin films. Ma optical parameters efirimu rakatetepa re optical anosanganisira refractive index, absorption coefficient uye film thin thin film. Nekuda kwe stoichiometric deviation muzvikamu zve optical thin film zvakagadzirwa nemaitiro chaiwo, chimiro hachisisina homogeneous uye dense, asi kune microstructures uye disadvantages dzakasiyana-siyana, dielectric film layer haisisina kujeka zvachose, uye kune weak absorption, nepo paine spatial non-uniformity uye phase anisotropy mu refractive index yefirimu, uye firimu harisisina interface isingaperi uye yakatsetseka. Zvinonyanya kukosha ndezvekuti, mukugadzirira chaiko, maparamita ekugadzirira firimu ane simba guru paparamita dzeoptical dzefirimu, saka kusimbiswa kweparamita dzeoptical dzefirimu panguva chaiyo kwakakosha zvikuru. Pamusoro pezvo, firimu rakatetepa reoptical semudziyo unoshandiswa munzvimbo chaiyo, pamusoro pehunhu hweoptical hwemudziyo unofanirwa kusangana nezvinodiwa, firimu kune zvimwe zvinhu zvakawanda zvakakosha zvisiri zveoptical zvinokanganisa kushandiswa kwefirimu, zvakaita sekunamatira kwefirimu, kushushikana kwefirimu, kuomarara kwefirimu uye kuomarara kwepamusoro uye kugona kwefirimu kutsungirira nharaunda nezvimwewo. Saka, zvakakosha kuyera nemazvo maparamita ese akasiyana-siyana kana hunhu hunokanganisa kushandiswa kwemidziyo yefirimu yakatetepa.
Kufambiswa kwemifananidzo nekuratidzira kwemafirimu matete kunoedzwa zvakanyanya uchishandisa maspectral test analyzers. Maspectral analyzers ekuongorora mafirimu e optical anogona kukamurwa kuita maUV-Vis spectrophotometers, infrared spectrophotometers uye infrared Fourier spectrometers zvichienderana nemabhendi akasiyana ekuyedza. Maviri ekutanga anoshandisa spectral spectroscopy principle yekuongorora nekuyedza system, yekupedzisira yakavakirwa pa principle yeinterference spectral analysis system. Nekuda kwemaumbirwo akasiyana ejometri uye maumbirwo emidziyo ye thin-film, kunyangwe zviyero zvese zve transmittance ne reflectance, asi kune maumbirwo akasiyana, kurongeka kwakasiyana kana zvinodiwa zvakasiyana zve polarization, zvinogona kuda nzira dzakasiyana dzekuyedza uye matekiniki.
