II-Teecentric LensIyilelwe ikakhulu ukulungisa i-palax yelensi yezamashishini lemizi-mveliso, kwaye inokuba kwinqanaba lomgama oluthile, ukuze amandla omdlalo ofunyenweyo akazukutshintsha, esi sicelo sibaluleke kakhulu kwityala alikho kwi umphezulu ofanayo.

Nge-Lens ekhethekileyo, ubude bayo obujolise kuyo bude, kwaye ubude belensi buhlala buhlala buncinci kunobude obugxile.

Iimpawu zeI-lenses yeTeecentric

Iimpawu zayo kukuba zinokwenza izinto ezikude zibonakala zikhulu kunobukhulu bawo, indawo ekude kakhulu okanye izinto zinokufotwa zicocekile kwaye zichazwe ngakumbi.

Iilensi zeTeecentric zizisa i-quatititity yovavanyo oluchanekileyo olusekwe kwimpawu zabo ezikhethekileyo zokungakhetheli: Ukusonjululwa okuphezulu, ubunzulu bendawo ye-ultra ebanzi, kunye noyilo olukhethekileyo olukhanyisiweyo.

I-lenserriccecric lenserric isetyenziswe ngokubanzi kwiminyhadala yemidlalo, izilwanyana zasendle kunye nefoto yendalo, kunye nokujonga iinkwenkwezi, kuba ezi zinto zihlala zifuna ukudubula okanye ukuqaphela izinto ukusuka kumgama omde. Iilensi zeTeecentric zinokuzisa izinto ezikude "kufutshane" ngelixa zigcina ingcaciso kunye neenkcukacha zomfanekiso.

Ukongeza, ngenxa yobude obunqabileyo beelensi zeTeecentric, banokufumana imvelaphi ebunzi kwaye bunzulu sentsimi, ukwenzela isifundo sibe sibalaseleyo xa kubhadula ukufota.

Ukuhlelwa kwesiseko se-lenserric yeTeectionric

Iilensi zeTeecricpic ikakhulu zahlulwe zangaphambi kwento ye-tendentheric ye-teacenthel, i-telecentral ye-tendacentrals kunye neelebhu zecala lasecaleni.

I-lens yento

I-telocentric lens yindawo yokumisa i-aperture ibekwe kwinqwelo moya yokugxila kwenkqubo yenkqubo, xa i-aperture ifakwe kwindiza yesikwere esijolise kuyo, nokuba umgama womgama uyatshintsha, kodwa ukuphakama komfanekiso kuyatshintsha ungatshintshi, oko kukuthi, ubungakanani bento yokulinganiswa ayitshintshi.

I-Lens yeNdawo yeTeacentric isetyenziselwa umlinganiso obonakalayo wemizi-mveliso, ukugqwetha kuncinci kakhulu, kwaye ukusebenza okuphezulu kungakwazi ukufezekisa ukugqwetha.

Imifanekiso yesikwere

I-lens yecala leTececentric ibeka i-adretrogm kwindiza egxile kwinqwelomoya ukuze i-ray yecala lecala lecala ihambelana ne-Axis ye-Axis. Ke ngoko, nangona indawo yokufaka yeCCD ye-CCD iguqukile, ubungakanani bomfanekiso oqikelelweyo kwi-CCD chip zihlala zingaguqukanga.

I-Bilateral Lens

Iilensi zeTelateral zidibanisa izibonelelo zezinto ezimbini ezingezantsi. Kumsebenzi wokulungisa umfanekiso, kuphela kuphela i-teectionric lenses isetyenzisiwe. Ngamaxesha athile, iilensi zefowuni kumacala omabini zisetyenziswa (ngokuqinisekileyo ixabiso liphezulu).

Kwicandelo lemifanekiso yokulungisa imizi-mveliso / umbono womatshini, i-teecceric lenses ngokubanzi ayisebenzi, ke lo mzi mveliso awuzisebenzisi.
