Iilensi ze-Optical zezinto ezibonakalayo zezinto ezibonakalayo ezinomgangatho ojiweyo onokuphinda ucofe kunye nokujonga ukukhanya. Zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo ze-optical ukunciphisa imitha yokukhanya, umbono olungisayo, izinto zokwenza amandla, kunye nokwenza imifanekiso. Iilensi zizinto ezibaluleke kakhulu kwiikhamera, iiteleskopu, i-microscopes, iiglasi zamehlo, iprojeki, kunye nezinye izixhobo ezininzi zamehlo.

Zimbini iintlobo zeelensi:

I-Convex (okanye i-covertive) iilensi: Ezi selses ziqaqambile embindini kunemiphetho, kwaye ziguqulela imitha yokukhanya ekhanyayo edlula kuyo ukuya kwindawo ekugxilwe kuyo kwilensi. Iilensi ze-convex zihlala zisetyenziswa kwiglasi enkulu, iikhamera, kunye neeglasi zamehlo ukuze zilungiselele ukubaluleka.

I-cocave (okanye i-wipering) iilensi: Ezi len zithambile embindini kunakwimiphetho, kwaye zibangela ukuba imitha yokukhanya ehambelana nayo idlula ngokungathi zivela kwinqaku elibonakalayo kwilensi. I-cocaule lenses ihlala isetyenziswa ekulungiseleleni uxinzelelo.

Iilensi zenziwe ngokusekwe kubude babo bokugxila, nto leyo kumgama ukusuka kwilensi ukuya kwindawo ekugxilwe kuyo. Ubude obugxile kwinqanaba lokukhanya kokukhanya kunye nokuqulunqwa komfanekiso okhokelela.

Amanye amanani aphambili ahambelana neelensi yokwakheka ziquka:

Indawo yokujonga: Inqaku apho kukhanya khona imitha okanye ukubonakala kuyinto yokuphambuka emva kokudlula kwilensi. I-lens ye-convex, yindawo apho kudibana khona. Kwilensi ye-concave, yindawo apho imigca ye-divergent ibonakala ivela khona.

Ubude obujolise kuyo: Umgama phakathi kwelensi kunye nendawo ekugxilwe kuyo. Yiparamitha ebalulekileyo echaza amandla e-len kunye nobungakanani bomfanekiso.

I-aperture: Ububanzi beelensi ezivumela ukukhanya. I-aperture enkulu ivumela ukukhanya okungakumbi ukuba kudlule, kukhokelela kumfanekiso okhaphukhaphu.

I-Axis ye-Optis: Umgca ophakathi udlula embindini weelensi kumphezulu wayo.

Amandla eLensi: Ukulinganiswa kwi-Diopters (d), amandla elensi abonisa amandla okuphikisana kwelensi. I-lenses yeConvex inamagunya aqinisekileyo, ngelixa iilensi ze-concave zinamandla amabi.

Iilensi ze-Optical ziguqukele kwiindawo ezahlukeneyo, ukusuka kwi-Istronomy kwiSayensi yoNyango, ngokusivumela ukuba sigcine izinto ezikude, kwaye senze iingxaki zombono, kwaye senze ingcinga kunye nemilinganiselo. Baqhubeka bedlala indima ebalulekileyo ekuqhubeni itekhnoloji kunye nokuhlolwa kwenzululwazi.
