Ukuchazwa kwefilimu ebhityileyo ye-optical kubandakanya ukuchazwa kweempawu ze-optical, iiparameter ze-optical kunye neempawu ezingezizo ze-optical, iipropati ze-optical ikakhulu zibhekisa kwiimpawu ze-spectral reflectance, transmittance kunye ne-optical loss (ilahleko yokufunxa kunye ne-reflection loss) zefilimu ebhityileyo ye-optical. Ukudluliselwa kunye nokubonakaliswa zezona mpawu ziphambili ze-optical films, ngoko ke uvavanyo lokudluliselwa kwefilimu ebhityileyo kunye ne-reflection yindlela yokuvavanya esisiseko yeefilimu ezibhityileyo ze-optical. Iiparameter ze-optical zefilimu ebhityileyo ye-optical ziquka i-refractive index, i-absorption coefficient kunye ne-film thin film ye-optical. Ngenxa yokuphambuka kwe-stoichiometric kwiindawo eziphathekayo zefilimu ebhityileyo ye-optical elungiselelwe yinkqubo yokwenyani, isakhiwo asisafani kwaye sixinene, kodwa kukho izakhiwo ezincinci kunye neziphene ezahlukeneyo, umaleko wefilimu ye-dielectric awusabonakali ngokupheleleyo, kwaye kukho ukufunxa okubuthathaka, ngelixa kukho ukungahambelani kwendawo kunye ne-phase anisotropy kwi-refractive index yefilimu, kwaye ifilimu ayiseyiyo i-interface engapheliyo negudileyo. Okubaluleke ngakumbi, kwinkqubo yokulungiselela ngokwenene, iiparameter zenkqubo yokulungiselela ifilimu zinempembelelo enkulu kakhulu kwiiparameter ze-optical zefilimu, ngoko ke ukuqinisekiswa kwexesha langempela kweeparameter ze-optical zefilimu kubaluleke kakhulu. Ukongeza, ifilimu encinci ye-optical njengesixhobo esisetyenziswa kwindawo yokwenyani, ukongeza kwiimpawu ze-optical zesixhobo kufuneka zihlangabezane neemfuno, ifilimu kukho ezinye iimpawu ezininzi ezibalulekileyo ezingezizo ze-optical ezichaphazela ukusetyenziswa kwefilimu, ezinje ngokunamathela kwefilimu, uxinzelelo lwefilimu, ubulukhuni befilimu kunye noburhabaxa bomphezulu kunye nokukwazi kwefilimu ukumelana nendawo yokusingqongileyo njalo njalo. Ke ngoko, kubalulekile ukulinganisa ngokuchanekileyo zonke iiparameter ezahlukeneyo okanye iimpawu ezichaphazela ukusetyenziswa kwezixhobo zefilimu encinci.
Ukudluliselwa kunye nokubonakaliswa kweefilimu ezincinci kuvavanywa kakhulu kusetyenziswa ii-spectral test analyzers. Ii-Spectral analyzers zovavanyo lwefilimu ye-optical zinokwahlulwa zibe yi-UV-Vis spectrophotometers, i-infrared spectrophotometers kunye ne-infrared Fourier spectrometers ngokweebhendi zovavanyo ezahlukeneyo. Ezimbini zokuqala zisebenzisa umgaqo we-spectral spectroscopy wohlalutyo kunye nenkqubo yovavanyo, le yokugqibela isekelwe kumgaqo wenkqubo yohlalutyo lwe-spectral interference. Ngenxa yezakhiwo ezahlukeneyo zejometri kunye neemilo zezixhobo ze-thin-film, nangona zonke iimilinganiselo zokudluliselwa kunye nokubonakaliswa, kodwa kwiimilo ezahlukeneyo, ukuchaneka okwahlukileyo okanye iimfuno ezahlukeneyo ze-polarization, zinokufuna iindlela ezahlukeneyo zovavanyo kunye neendlela.
