Hona jwale, indasteri e ntse e ntshetsa pele dikobo tsa mahlo bakeng sa ditshebediso tse kang dikhamera tsa dijithale, di-scanner tsa khoutu ya bar, di-sensor tsa fiber optic le marangrang a puisano, le ditsamaiso tsa tshireletso ya biometric. Ha mmaraka o ntse o hola ka lebaka la dikarolo tsa polasetiki tsa mahlo tse theko e tlase le tse sebetsang hantle, ho hlahile mahlale a mang a matjha a ho kobo ho fihlela ditlhoko tsa ditshebediso tse ntjha.
Ha ho bapisoa le optic ea khalase, optic ea polasetiki e bobebe ka makhetlo a 2 ho isa ho a 5, e leng se etsang hore e be e loketseng haholoanyane bakeng sa lits'ebetso tse kang lihelmete tsa pono ea bosiu, lits'ebetso tsa ho nka litšoantšo tse nkehang habonolo, le lisebelisoa tsa bongaka tse ka sebelisoang hape kapa tse lahloang (mohlala, li-laparoscope). Ho phaella moo, optic ea polasetiki e ka bōptjoa ho latela litlhoko tsa ho kenya, ka hona ho fokotsa haholo palo ea mehato ea kopano le ho fokotsa litšenyehelo tsa tlhahiso.
Li-optics tsa polasetiki li ka sebelisoa lits'ebetsong tse ngata tsa leseli le bonahalang. Bakeng sa lits'ebetso tse ling tse haufi le UV le haufi le IR, lisebelisoa tse tloaelehileng tse kang acrylic (ponahalo e ntle haholo), polycarbonate (matla a tšusumetso e ntle ka ho fetisisa) le li-olefin tse potolohang (ho hanyetsa mocheso o phahameng le ho tšoarella, ho monya metsi a tlase) li na le sebaka sa bolelele ba phetisetso ea 380 ho isa ho 100 nm). Ho koahela ho eketsoa holim'a likarolo tsa polasetiki tsa optical ho ntlafatsa ts'ebetso ea tsona ea phetisetso kapa ponts'o le ho eketsa ho tšoarella. Li-optics tse teteaneng (hangata tse ka bang 1 μm botenya kapa bo botenya) li sebetsa haholo-holo e le mekhahlelo e sireletsang, empa hape li ntlafatsa ho khomarela le ho tiea bakeng sa li-optics tse latelang tse tšesaane. Li-optics tse tšesaane li kenyelletsa silicon dioxide (SiO2), tantalum oxide, titanium oxide, aluminium oxide, niobium oxide, le hafnium oxides (SiO2, Ta2O5, TiO2, Al2O3, Nb3O5, le HfO2); li-optics tse tloaelehileng tsa seipone sa tšepe ke aluminium (Al), silevera (Ag), le khauta (Au). Fluoride kapa nitride ha e sebelisoe hangata bakeng sa ho koahela, hobane ho fumana boleng bo botle ba ho koahela, ho hlokahala mocheso o phahameng, e leng se sa tsamaellaneng le maemo a tlase a ho boloka mocheso a hlokahalang bakeng sa ho koahela likarolo tsa polasetiki.
Ha boima, litšenyehelo le bonolo ba ho kopanya e le lintho tsa bohlokoa tsa ho nahana ka ho sebelisa likarolo tsa mahlo, likarolo tsa polasetiki tsa mahlo hangata ke khetho e ntle ka ho fetisisa.
Di-optics tse bonahatsang tse ikgethileng bakeng sa sekene se ikgethileng, tse nang le letoto la dikarolo tse chitja le tse seng chitja (Aluminium e manehilweng le tse sa manehwang).
Sebaka se seng se tloaelehileng sa ts'ebeliso bakeng sa likarolo tsa polasetiki tse koahetsoeng ke masela a mahlo. Hona joale masela a thibelang ho bonahatsa (AR) lilenseng tsa khalase ea mahlo a tloaelehile haholo, 'me likhalase tsohle tsa mahlo tse fetang 95% li sebelisa lilense tsa polasetiki.
Tšimo e 'ngoe ea ts'ebeliso bakeng sa likarolo tsa polasetiki tsa optical ke lisebelisoa tsa sefofane. Mohlala, ts'ebelisong ea ponts'o ea li-head-up (HUD), boima ba karolo ke ntho ea bohlokoa ho ela hloko. Likarolo tsa polasetiki tsa optical li loketse lits'ebetso tsa HUD. Joalo ka litsamaiso tse ling tse ngata tse rarahaneng tsa optical, li-coat tse thibelang khanya lia hlokahala ho li-HUD ho qoba leseli le hasaneng le bakoang ke mesi e lahlehileng. Le hoja lifilimi tsa tšepe tse bonahatsang haholo le tse ntlafatsang oxide tse nang le mekhahlelo e mengata le tsona li ka koaheloa, indasteri e hloka ho nts'etsapele mahlale a macha khafetsa ho ts'ehetsa likarolo tsa polasetiki tsa optical lits'ebetsong tse ntseng li hlaha.
