Iilensi ezarahliweyo ziilensi ezivumela kuphela ukukhanya kwindawo ethile yokugcwala kwendalo ekukhanyiseni kwendalo ukudlula. Ngenxa yesiphumo sayo sokucoca, sinxibe izinto ezimnyama izinto xa uzijonga. Ukwenzela ukucoca ukukhanya kwelanga kwigumbi elinye kunye nomphezulu wamanzi, umhlaba okanye ikhephu, ukudibanisa okukhethekileyo kongezwa kwilensi, ebizwa ngokuba yilensi ye-len.
Impembelelo ekhethekileyo ye-lenser ekhethekileyo ukuba ayibandakanyi kwaye icebo lokucoca isibane esivela kumqadi. Ukukhanya kunokubekwa kumfanekiso wombono wamehlo kwi-axis yodluliselo lwendlela elungileyo, ukuze intsimi yombono icacile kwaye yendalo. Njengomgaqo wemfama, ukukhanya kulungiswa ukuba ungene kwigumbi elikwindlela efanayo, ngokwemvelo kwenza imeko ijongeka ityhafile kwaye ingakhathali.
Iilensi ezarahliweyo zisetyenziswa kakhulu kwizicelo zokuphumla, ezizixhobo ezifanelekileyo kubanini bemoto kunye nenzondelelo yokuloba, enokunceda abaqhubi abaziincamsanga eziphezulu kwaye bavumele inzondelelo yokuloba ukuze babone intlanzi emanzini.
I-polarization inokwahlulwa yahlulwe yaba ziindidi ezintathu, ezizezisi-mgca kwi-colarization, i-elliptical polilization, kunye nokulinganisa okujikelezayo. Ngokubanzi, oko kwabizwa ngokuba kukungaqondakali kubhekisa kwindalo ekumgangatho, okwabizwa ngokuba nguPolization weRhafu. Ukuntywila kwale phunga lokukhanya kumiselwa kwicala elithile, indlela yokusasazeka kwindawo ye-sinsussoidal, kunye nokuqikelelwa kwindiza yendlela yokuhamba ngokuthe nkqo ngumgca othe nkqo. UMGAQO-NKQUBO kwaye icacile.
Iilensi zethu ezichithwayo zisebenzisa izixhobo ezikhethiweyo kunye neenkqubo ezigqibeleleyo zefilimu, ezidibeneyo zefilimu edibeneyo ngomdibaniso wesithamo. I-fildional yefilimu, efana ne-shutter yocingo, iya kuthatha konke ukukhanya okungagungqiyo. Ngokukhanya okuthe nkqo, icebo lokucoca, banokuvimba i-ultraviolet ray ukuqinisekisa umbono okhululekileyo. Iilensi eziphalazelayo zinokufanelekela ukuqhuba, i-Seaside, ukhenketho, ibhayisikile, imidlalo yebhola kunye nezinye iimeko. Qala umbono okhululekileyo apha.
