IiLensi zePlano-Concave PDF uMzobo

Iilensi zamehlo zizinto ezibonakalayo ezibonisa ukukhanya kunye nemigangatho egobileyo enokuthi i-refract kwaye igxile ekukhanyeni. Zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zamehlo ukuze zilawule imitha yokukhanya, ukulungisa umbono, ukukhulisa izinto, kunye nokwenza imifanekiso. Iilensi zizinto ezibalulekileyo kwiikhamera, iiteleskopu, iimikroskopu, iindondo, iiprojektha nezinye izixhobo zamehlo ezininzi.

Kukho iindidi ezimbini eziphambili zeelensi:

Iilensi zeConvex (okanye eziguqukayo).: Ezi lens zijiyile embindini kunasezincamini, kwaye zidibanisa imitha yokukhanya ehambelanayo edlula kuzo iye kwindawo ekugxilwe kuyo kwelinye icala lelensi. Iilensi zeconvex zidla ngokusetyenziswa ekwenzeni iindondo zokukhulisa, iikhamera, neendondo zamehlo ukulungisa ukubona kude.

Iilensi zeConcave (okanye diverging).: Ezi lensi zibhityile embindini kunasemiphethweni, kwaye zenza imitha yokukhanya ehambelanayo edlula kuzo ijike ngokungathi ivela kwindawo ekugxilwe kuyo enenyani kwicala elinye lelensi. Iilensi zeconcave zidla ngokusetyenziswa ekulungiseni ukubona kufutshane.

Iilensi ziyilwe ngokusekwe kubude bazo obujongisiweyo, obungumgama ukusuka kwilensi ukuya kwindawo ekugxilwe kuyo. Ubude bokujongwa bumisela iqondo lokugoba kokukhanya kunye nokwakheka komfanekiso okubangelwayo.

Amanye amagama aphambili anxulumene neelensi zamehlo abandakanya:

Indawo yokujonga: Indawo apho imitha yokukhanya idibana khona okanye ibonakala iyaphambuka emva kokudlula kwilensi. Kwilensi yeconvex, yindawo apho imitha ye-parallel idibana khona. Kwilensi yeconcave, yindawo apho imitha ehlukeneyo ibonakala ivela khona.

Ubude bojoliso: Umgama phakathi kwelensi kunye nendawo ekugxilwe kuyo. Yiparameter ebalulekileyo echaza amandla elensi kunye nobukhulu bomfanekiso owenziweyo.

Umngxuma wokuvula: Ubukhulu be-lens obuvumela ukukhanya ukuba kudlule. Imbobo enkulu ivumela ukukhanya okungakumbi ukuba kudlule, okukhokelela kumfanekiso oqaqambileyo.

Umgca we-Optical: Umgca osembindini odlula embindini welensi ethe gqolo ukuya kumphezulu wayo.

Amandla eLens: Ilinganiswe kwi-diopters (D), amandla e-lens abonisa amandla okuhlaziya i-lens. Iilensi zeconvex zinamandla alungileyo, ngelixa iilensi zeconcave zinamandla angalunganga.

Iilensi zamehlo ziye zaguqula imimandla eyahlukahlukeneyo, ukusuka kwinzululwazi ngeenkwenkwezi ukuya kwinzululwazi yezonyango, ngokusivumela ukuba sijonge izinto ezikude, silungise iingxaki zokubona, size senze umfanekiso-ngqondweni kunye nemilinganiselo echanekileyo. Baqhubeka bedlala indima ebalulekileyo ekuqhubeleni phambili iteknoloji kunye nokuhlola kwenzululwazi.
