Ukubonakaliswa kwefilimu encinci ye-optical ibandakanya ukubonakaliswa kweempawu ze-optical properties, iiparameters ze-optical kunye ne-non-optical properties, iipropathi ze-optical zibhekiselele kwi-spectral reflectance, transmittance and optical loss (i-absorption loss and reflection loss) iipropati zefilimu encinci ye-optical. Ukuhanjiswa kunye nokubonakalisa ezona mpawu zisisiseko zeefilim ezibhityileyo, ngoko ke ukuvavanywa kokuhanjiswa kwefilimu ebhityileyo kunye nokubonakaliswa yeyona ndlela isisiseko yovavanyo lweefilimu ezibhityileyo. Iiparamitha ze-Optical optical optical optical film ibandakanya isalathiso se-refractive, i-absorption coefficient kunye nobukhulu befilimu yefilimu encinci ye-optical. Ngenxa yokuphambuka kwe-stoichiometric kumacandelo ezinto zefilimu ebhityileyo elungiselelwe yinkqubo yokwenyani, ulwakhiwo alusekho homogeneous kwaye luxinene, kodwa kukho i-microstructures kunye neziphene ezahlukeneyo, umaleko wefilimu ye-dielectric ayisekho elubala ngokupheleleyo, kwaye kukho ukufunxa obuthathaka, ngelixa kukho indawo engafaniyo neyokubumbana kwifilimu kunye ne-filimi esebenzayo kunye ne-filimi. ujongano olungenasiphelo nolugudileyo. Okubaluleke ngakumbi, kwinkqubo yokulungiswa kwangempela, iiparitha zenkqubo yokulungiselela ifilimu zinempembelelo enkulu kakhulu kwiiparamitha ze-optical zefilimu, ngoko ke ukuqinisekiswa kwexesha langempela leepharamitha ze-optical zefilimu kubaluleke kakhulu. Ukongeza, ifilimu ebonakala ibhityile njengesixhobo esisetyenziswa kwindawo eyiyo, ukongeza kwiimpawu zokukhanya zesixhobo kufuneka zihlangabezane neemfuno, ifilimu kukho ezinye iimpawu ezibalulekileyo ezingezizo ezichaphazela ukusetyenziswa kwefilimu, njengokuncamathela kwefilimu, uxinzelelo lwefilimu, ubulukhuni befilimu kunye noburhabaxa bomphezulu kunye nokukwazi kwefilimu ukumelana nokusingqongileyo njalo njalo. Ngoko ke, kubalulekile ukulinganisa ngokuchanekileyo zonke iiparitha ezahlukeneyo okanye iimpawu ezichaphazela ukusetyenziswa kwezixhobo zefilimu ezincinci.
Ukuhanjiswa kunye nokubonakaliswa kweefilimu ezincinci zivavanywa ikakhulu kusetyenziswa abahlalutyi bovavanyo lwe-spectral. Abahlalutyi be-Spectral kuvavanyo lwefilim yamehlo banokohlulwa babe yi-UV-Vis spectrophotometers, i-infrared spectrophotometers kunye ne-infrared i-Fourier spectrometers ngokweebhendi zovavanyo ezahlukeneyo. Ababini bokuqala basebenzisa umgaqo we-spectral spectroscopy wokuhlalutya kunye nenkqubo yokuvavanya, le yokugqibela isekelwe kumgaqo wokuphazamiseka kwenkqubo yohlalutyo lwe-spectral. Ngenxa yolwakhiwo olwahlukileyo lwejometri kunye neemilo zezixhobo zefilim ebhityileyo, nangona zonke imilinganiselo yokudlulisa kunye nembonakalo, kodwa kwiimilo ezahlukeneyo, ukuchaneka okwahlukileyo okanye iimfuno ezahlukeneyo zepolarization, kunokufuna iindlela ezahlukeneyo zovavanyo kunye nobuchule.
