Ilensi ye-IR eLungisiweyo, eyaziwa ngokuba yi-infrared corrected lens, luhlobo oluphucukileyo lwelensi yokukhanya elungiswe kakuhle ukuze inike imifanekiso ecacileyo nebukhali kuzo zombini iispectrum zokukhanya ezibonakalayo kunye ne-infrared. Oku kubaluleke ngakumbi kwiikhamera zokucupha ezisebenza imini yonke, njengoko iilensi eziqhelekileyo zidla ngokuphulukana nokugxila xa zitshintsha ukusuka ekukhanyeni kwemini (ukukhanya okubonakalayo) ukuya kukukhanya kwe-infrared ebusuku.
Xa i-lens yesiqhelo ibonakaliswe kukukhanya kwe-infrared, amaza okukhanya ahlukeneyo awahlangani kwindawo enye emva kokudlula kwi-lens, ekhokelela kwinto eyaziwa ngokuba yi-chromatic aberration. Oku kuphumela kwimifanekiso engaphandle kwengqwalasela kunye nokuthotywa komgangatho womfanekiso xa ukhanyiswa sisibane se-IR, ngakumbi kwiiperipheries.
Ukuchasana noku, iilensi eziLungisiweyo ze-IR ziyilwe ngezinto ezikhethekileyo zamehlo ezihlawulela ukutshintshwa kogxininiso phakathi kokukhanya okubonakalayo kunye ne-infrared. Oku kuphunyezwa ngokusetyenziswa kwemathiriyeli enezalathisi ezithile ezibonisa ukugqabhuka kunye neelensi eziyilwe ngokukodwa iilensi ezinceda ekugxininiseni imibhobho yokukhanya kwinqwelomoya enye, eqinisekisa ukuba ikhamera inokugcina ugxininiso olubukhali nokuba indawo ilayitiwe kukukhanya kwelanga, ukukhanya kwangaphakathi, okanye imithombo yokukhanya ye-infrared.
Ukuthelekiswa kwemifanekiso yovavanyo lwe-MTF emini (phezulu) nasebusuku (ezantsi)
Iilensi ezininzi ze-ITS ezizimeleyo eziphuhliswe nguChuangAn Optoelectronics nazo ziyilwe ngokusekelwe kumgaqo wokulungisa we-IR.
Kukho iingenelo ezininzi zokusebenzisa ilensi eLungisiweyo ye-IR:
1. Ukucaciswa koMfanekiso okongeziweyo: Naphantsi kweemeko zokukhanya ezahlukeneyo, i-IR eLungisiweyo ilensi igcina ubukhali kunye nokucaca kuyo yonke indawo yokujonga.
2. ULungelo oluPhuculweyo: Ezi lensi zenza ukuba iikhamera zokhuseleko zithathe imifanekiso ekumgangatho ophezulu kwiimeko ezahlukeneyo zokusingqongileyo, ukusuka ekukhanyeni kwemini ukuya kubumnyama obupheleleyo kusetyenziswa ukukhanya kwe-infrared.
3. I-Versatility: Iilensi ezichanekileyo ze-IR zinokusetyenziswa kwiikhamera ezininzi kunye nezicwangciso, ezizenza zibe lukhetho oluguquguqukayo kwiimfuno ezininzi zokucupha.
4. Ukucuthwa kwe-Focus Shift: Uyilo olukhethekileyo lunciphisa ukutshintshwa kwengqwalasela eyenzeka ngokuqhelekileyo xa utshintshela ekukhanyeni okubonakalayo ukuya kwisibane se-infrared, ngaloo ndlela kuncitshiswa imfuno yokujolisa kwakhona ikhamera emva kweeyure zokukhanya.
Iilensi eziLungisiweyo ze-IR ziyinxalenye ebalulekileyo kwiinkqubo zanamhlanje zokucupha, ngakumbi kwiindawo ezifuna ukubekwa esweni kwe-24/7 kunye nezo zithi zibe notshintsho olukhulu ekukhanyeni. Baqinisekisa ukuba iinkqubo zokhuseleko zinokusebenza ngokuthembekileyo ngokusemandleni abo, kungakhathaliseki ukuba iimeko zokukhanyisa ezikhoyo.
