Isici sefilimu elincanyana le-optical lihlanganisa ukubonakaliswa kwezakhiwo ze-optical, imingcele ye-optical kanye nezakhiwo ezingezona ezibonakalayo, izakhiwo ze-optical ikakhulukazi zibhekisela ekukhanyeni kwe-spectral, ukudlulisa kanye nokulahlekelwa kwe-optical (ukulahlekelwa ukumuncwa kanye nokulahlekelwa kokucabangela) izakhiwo zefilimu elincanyana le-optical. I-Transmittance and reflectance yizona zinto eziyisisekelo kakhulu ze-optical optical films ezacile, ngakho-ke ukuhlolwa kokudluliswa kwefilimu emincane nokubukeka kuyindlela eyisisekelo yokuhlola amafilimu amancane abonakalayo. Imingcele yokubona yefilimu elizacile ihlanganisa inkomba ye-refractive, i-coefficient yokumuncwa kanye nogqinsi lwefilimu yefilimu elikhanyayo elincanyana. Ngenxa yokuphambuka kwe-stoichiometric ezingxenyeni ezibonakalayo zefilimu elincanyana elikhanyayo elilungiselelwe inqubo yangempela, isakhiwo asisafani futhi siminyene, kodwa kukhona ama-microstructures namaphutha ahlukahlukene, ungqimba lwefilimu ye-dielectric alusabonakali ngokuphelele, futhi kukhona ukumuncwa okubuthakathaka, kuyilapho kukhona indawo engafani nenye futhi ifilimu ye-afractive ifilimu, futhi ifilimu ye-index esebenzayo. isikhombikubona esingapheli nesibushelelezi. Okubaluleke nakakhulu, ohlelweni lwangempela lokulungiselela, imingcele yenqubo yokulungiselela ifilimu inomthelela omkhulu kakhulu kumingcele ye-optical yefilimu, ngakho-ke ukuqinisekiswa kwesikhathi sangempela kwemingcele ye-optical yefilimu kubaluleke kakhulu. Ngaphezu kwalokho, ifilimu elikhanyayo elincanyana njengethuluzi elisetshenziswa endaweni yangempela, ngaphezu kwezici zokubona zedivayisi idinga ukuhlangabezana nezidingo, kunezinye izici eziningi ezibalulekile ezingezona ezibonakalayo ezithinta ukusetshenziswa kwefilimu, njengokunamathela kwefilimu, ukucindezelwa kwefilimu, ubulukhuni befilimu nobulukhuni bobuso kanye nekhono lefilimu lokumelana nemvelo nokunye. Ngakho-ke, kubalulekile ukulinganisa ngokunembile yonke imingcele ehlukahlukene noma izici ezithinta ukusetshenziswa kwamadivayisi wefilimu emincane.
Ukudluliswa nokubonakaliswa kwamafilimu amancane kuhlolwa ikakhulukazi kusetshenziswa abahlaziyi bokuhlola okubonwayo. Izihlaziyo ze-Spectral zokuhlolwa kwefilimu ebonakalayo zingahlukaniswa zibe ama-spectrophotometers e-UV-Vis, ama-spectrophotometers e-infrared kanye nama-infrared Fourier spectrometers ngokuya ngamabhendi ahlukene okuhlola. Amabili okuqala asebenzisa isimiso se-spectral spectral sokuhlaziya nohlelo lokuhlola, lesi sakamuva sisekelwe esimisweni sohlelo lokuhlaziya i-spectral yokuphazamiseka. Ngenxa yezakhiwo ezihlukene zejiyomethri kanye nokwakheka kwemishini yefilimu emincane, nakuba zonke izilinganiso zokudlulisela nokubonisa, kodwa ngomumo ohlukene, ukunemba okuhlukile noma izidingo ezihlukene ze-polarization, zingadinga izindlela nezindlela zokuhlola ezihlukene.
