Kufotokozera kwa filimu yopyapyala ya kuwala kumaphatikizapo kufotokoza za mawonekedwe a kuwala, magawo a kuwala ndi mawonekedwe osakhala a kuwala, mawonekedwe a kuwala makamaka amatanthauza mawonekedwe a spectral reflection, transmittance ndi optical loss (absorption loss and reflection loss) a filimu yopyapyala ya kuwala. Kufotokozera ndi kuwunikira ndi mawonekedwe oyambira kwambiri a mafilimu opyapyala a kuwala, kotero kuyesa kwa transmittance ndi reflection ya filimu yopyapyala ya kuwala ndi njira yoyambira yoyesera mafilimu opyapyala a kuwala. Magawo a kuwala a filimu yopyapyala ya kuwala akuphatikizapo refractive index, absorption coefficient ndi film thin thin film ya filimu yopyapyala ya kuwala. Chifukwa cha stoichiometric deviation mu zigawo za filimu yopyapyala ya kuwala yokonzedwa ndi njira yeniyeni, kapangidwe kake sikali kofanana komanso kolimba, koma pali microstructures ndi zolakwika zosiyanasiyana, dielectric film layer siilinso yowonekera bwino, ndipo pali kufooka kwa kuyamwa, pomwe pali malo osagwirizana ndi phase anisotropy mu refractive index ya filimu, ndipo filimuyo siilinso mawonekedwe opanda malire komanso osalala. Chofunika kwambiri, mu ndondomeko yeniyeni yokonzekera, magawo a njira yokonzekera filimu amakhudza kwambiri magawo a kuwala a filimuyi, kotero kutsimikizira nthawi yeniyeni kwa magawo a kuwala a filimuyi ndikofunikira kwambiri. Kuphatikiza apo, filimu yopyapyala yowala ngati chipangizo chomwe chimagwiritsidwa ntchito m'malo enieni, kuwonjezera pa mawonekedwe a kuwala a chipangizocho imafunika kukwaniritsa zofunikira, filimuyi ili ndi makhalidwe ena ambiri osakhala a kuwala omwe amakhudza kugwiritsa ntchito filimuyi, monga kumatira filimu, kupsinjika kwa filimu, kuuma kwa filimu ndi kukhwima kwa pamwamba komanso kuthekera kwa filimuyi kupirira chilengedwe ndi zina zotero. Chifukwa chake, ndikofunikira kuyeza molondola magawo osiyanasiyana kapena makhalidwe omwe amakhudza kugwiritsa ntchito zida zopyapyala za filimuyi.
Kutumiza ndi kuwunika kwa mafilimu owonda kumayesedwa makamaka pogwiritsa ntchito ma spectral test analyzers. Ma spectral analyzers oyesera mafilimu owoneka amatha kugawidwa m'ma spectrophotometers a UV-Vis, ma infrared spectrophotometers ndi ma infrared Fourier spectrometers malinga ndi magulu osiyanasiyana oyesera. Awiri oyamba amagwiritsa ntchito mfundo ya spectral spectroscopy yowunikira ndi kuyesa, yomalizayi imachokera pa mfundo ya kusokoneza ma spectral analysis system. Chifukwa cha kapangidwe ndi mawonekedwe osiyanasiyana a zida zopyapyala, ngakhale kuti miyeso yonse ya transmittance ndi reflectionance, koma pa mawonekedwe osiyanasiyana, kulondola kosiyana kapena zofunikira zosiyanasiyana za polarization, zingafunike njira ndi njira zosiyanasiyana zoyesera.
