Ukusetyenziswa kweefilimu ezithambileyo ze-optical kwiimveliso ze-elektroniki zabathengi ezifana neefowuni eziphathwayo kuye kwatshintsha ukusuka kwiilensi zekhamera zemveli ukuya kwicala elahlukeneyo, njengeelensi zekhamera, izikhuseli zelensi, izihluzi ze-infrared cutoff (IR-CUT), kunye ne-NCVM coating kwizigqubuthelo zebhetri zefowuni.
Isihluzo se-IR-CUT esikhethekileyo sekhamera sibhekisa kwisihluzo esihluza ukukhanya kwe-infrared phambi kwento ethambileyo ye-semiconductor (i-CCD okanye i-CMOS), okwenza umbala wokuphinda uvele womfanekiso wekhamera uhambelane nombala okwindawo. Esona sisetyenziswa kakhulu sisihluzo esinqunyiweyo se-650 nm. Ukuze sisetyenziswe ebusuku, kusetyenziswa izihluzo ezinqunyiweyo ze-850 nm okanye ze-940 nm, kwaye kukwakho nezihluzo ezisetyenziswa kabini emini nasebusuku okanye ezisetyenziswa ebusuku.
Itekhnoloji yokuqaphela ubuso ngokukhanya okucwangcisiweyo (i-Face ID) isebenzisa ii-laser ze-940 nm, ngoko ke ifuna izihluzi ze-940 nm narrowband, kwaye ifuna utshintsho oluncinci kakhulu lwee-engile.
Ilensi yekhamera yefowuni ephathwayo igqunywe kakhulu ngefilimu yokuthintela ukukhanya ukuze kuphuculwe umgangatho womfanekiso, kuquka ifilimu yokuthintela ukukhanya ebonakalayo kunye nefilimu yokuthintela ukukhanya kwe-infrared. Ukuze kuphuculwe ukucoceka komphezulu ongaphandle, ifilimu yokuthintela ukungcola (AF) idla ngokugqunywa kumphezulu ongaphandle. Umphezulu weefowuni eziphathwayo kunye nezibonisi zephaneli ezisicaba zihlala zisebenzisa unyango lomphezulu we-AR+AF okanye we-AF ukunciphisa ukukhanya kunye nokuphucula ukufundeka elangeni.
Ngokufika kwe-5G, izixhobo zokugquma ibhetri zaqala ukuguquka ukusuka kwisinyithi ukuya kwi-non-metallic, njengeglasi, iplastiki, iiseramikhi, njalo njalo. Itekhnoloji yefilimu ebhityileyo ye-Optical isetyenziswa kakhulu ekuhombiseni izigqubuthelo zebhetri kwiifowuni eziphathwayo ezenziwe ngezi zinto. Ngokwethiyori yeefilimu ezibhityileyo ze-optical, kunye nenqanaba lophuhliso lwangoku lwezixhobo kunye netekhnoloji yokugquma ye-optical, phantse naluphi na ubonakaliso kunye naluphi na umbala lunokufezekiswa ngeefilimu ezibhityileyo ze-optical. Ukongeza, inokudityaniswa nee-substrates kunye ne-textures ukuze kulungiswe iziphumo ezahlukeneyo zokubonakala kombala.
