Iilensi zePlano-Concave Umzobo wePDF

Iilensi ze-Optical zizinto ezibonakalayo ezibonakalayo ezineendawo ezigobileyo ezinokujika zize zigxile ekukhanyeni. Zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo ze-optical ukulawula imisebe yokukhanya, ukulungisa umbono, ukukhulisa izinto, nokwenza imifanekiso. Iilensi zizinto ezibalulekileyo kwiikhamera, iiteleskopu, iimayikroskopu, iiglasi zamehlo, iiprojektha, kunye nezinye izixhobo ezininzi ze-optical.

Kukho iintlobo ezimbini eziphambili zeelensi:

Iilensi ezidityanisiweyo (okanye ezidityanisiweyo): Ezi lensi zijiyile embindini kunasemaphethelweni, kwaye zidibana nemisebe yokukhanya ehambelanayo edlula kuzo iye kwindawo egxile kwelinye icala lelensi. Iilensi ezijiyileyo zisetyenziswa kakhulu ekukhuliseni iiglasi, iikhamera, kunye neeglasi zamehlo ukulungisa ukubona kude.

Iilensi ezigobileyo (okanye eziguquguqukayo): Ezi lensi zincinci embindini kunasemaphethelweni, kwaye zibangela ukuba imisebe yokukhanya ehambelanayo edlula kuzo yahlukane ngokungathi ivela kwindawo ebonakalayo kwicala elinye lelensi. Iilensi ezigobileyo zihlala zisetyenziswa ukulungisa ukubona okukufutshane.

Iilensi zenziwe ngokusekelwe kubude bazo obuphambili, obungumgama ukusuka kwilensi ukuya kwindawo ephambili. Ubude obuphambili bumisela ubungakanani bokugoba kokukhanya kunye nokwenziwa komfanekiso ophumayo.

Amanye amagama abalulekileyo anxulumene neelensi zokukhanya aquka:

Indawo yokujonga: Indawo apho imisebe yokukhanya idibana okanye ibonakala ngathi iyahlukana emva kokudlula kwilensi. Kwilensi engqukuva, yindawo apho imisebe ehambelanayo idibana khona. Kwilensi engqukuva, yindawo apho imisebe engqukuva ibonakala ngathi ivela khona.

Ubude befokhalthi: Umgama phakathi kwelensi nendawo ephambili. Yiparameter ebalulekileyo echaza amandla elensi kunye nobukhulu bomfanekiso owenziweyo.

Imbobo: Ububanzi belensi obuvumela ukukhanya ukuba kudlule. Imbobo enkulu ivumela ukukhanya okungakumbi ukuba kudlule, nto leyo ebangela umfanekiso oqaqambileyo.

I-axis yokubonisa: Umgca ophakathi odlula embindini welensi ngokuthe nkqo ukuya kumphezulu wayo.

Amandla eelensi: Xa ilinganiswa ngee-diopter (D), amandla elensi abonisa amandla okujika kwelensi. Iilensi ezingqukuva zinamandla amahle, ngelixa iilensi ezingqukuva zinamandla amabi.

Iilensi ze-optical ziye zatshintsha iinkalo ezahlukeneyo, ukusuka kwi-astronomy ukuya kwi-medical science, ngokusivumela ukuba sibone izinto ezikude, silungise iingxaki zokubona, kwaye senze imifanekiso echanekileyo kunye nokulinganisa. Ziyaqhubeka nokudlala indima ebalulekileyo ekuphuculeni ubuchwepheshe kunye nophando lwesayensi.
