I-IR Corrected lens, eyaziwa nangokuthi ilensi elungisiwe ye-infrared, iwuhlobo oluyinkimbinkimbi lwamalensi okubona olulungiswe kahle ukuze lunikeze izithombe ezicacile nezibukhali kukho kokubili ukukhanya okubonakalayo kanye ne-infrared light spectrum. Lokhu kubaluleke kakhulu kumakhamera agadayo asebenza ubusuku nemini, njengoba amalensi avamile evame ukulahlekelwa ukugxila lapho eshintsha kusukela emini (ukukhanya okubonakalayo) ukuya ekukhanyeni kwe-infrared ebusuku.
Uma i-lens evamile ivezwa ekukhanyeni kwe-infrared, amaza ahlukene okukhanya awahlangani endaweni efanayo ngemva kokudlula kulensi, okuholela kulokho okwaziwa ngokuthi i-chromatic aberration. Lokhu kuphumela ezithombeni ezingagxilile kanye nekhwalithi yesithombe eyonakele lapho sikhanyiswa ukukhanya kwe-IR, ikakhulukazi emaphethelweni.
Ukuze umelane nalokhu, amalensi Alungiswa Nge-IR aklanywe ngezinto ezikhethekile zokubona ezinxephezela ukushintsha kokugxilisa ingqondo phakathi kokukhanya okubonakalayo kanye ne-infrared. Lokhu kufinyelelwa ngokusetshenziswa kwezinto ezinezinkomba ezithile ezibonisa ukugqama kanye namalensi aklanywe ngokukhethekile asiza ukugxilisa ama-spectrum okukhanya endizeni efanayo, okuqinisekisa ukuthi ikhamera ingakwazi ukulondoloza ukugxila okubukhali kungakhathaliseki ukuthi isehlakalo sikhanyiswa ukukhanya kwelanga, ukukhanya kwangaphakathi, noma imithombo yokukhanya kwe-infrared.
Ukuqhathaniswa kwezithombe zokuhlolwa kwe-MTF phakathi nosuku (phezulu) nasebusuku (ngezansi)
Amalensi amaningana e-ITS athuthukiswe ngokuzimela yi-ChuangAn Optoelectronics nawo aklanywa ngokusekelwe kumgomo wokulungisa we-IR.
Kunezinzuzo ezimbalwa zokusebenzisa ilensi elungiswe yi-IR:
1. Ukucaca Kwesithombe Okuthuthukisiwe: Ngisho nangaphansi kwezimo zokukhanya ezihlukahlukene, ilensi ye-IR Corrected igcina ukucijile nokucaca kuyo yonke inkundla yokubuka.
2. Ukuqapha Okuthuthukisiwe: Lawa ma-lens enza amakhamera okuvikela akwazi ukuthatha izithombe zekhwalithi ephezulu ezimweni ezihlukahlukene zemvelo, kusukela ekukhanyeni kwasemini kuya ebumnyameni obuphelele esebenzisa ukukhanya kwe-infrared.
3. Ukuguquguquka: Amalensi alungisiwe e-IR angasetshenziswa kuhlu olubanzi lwamakhamera nezilungiselelo, okuwenza abe yinketho evumelana nezimo ngezidingo eziningi zokugada.
4. Ukwehliswa kwe-Focus Shift: Idizayini ekhethekile inciphisa ukushintsha kokugxila okuvame ukwenzeka lapho usuka ekukhanyeni okubonakalayo kuye kwe-infrared, ngaleyo ndlela yehlise isidingo sokuphinda ugxilise ikhamera ngemva kwamahora okukhanya kwasemini.
Amalensi alungisiwe e-IR ayingxenye ebalulekile ezinhlelweni zesimanje zokugada, ikakhulukazi ezindaweni ezidinga ukuqapha okungu-24/7 kanye nalezo ezihlangabezana nezinguquko ezinkulu ekukhanyeni. Baqinisekisa ukuthi amasistimu okuvikela angakwazi ukusebenza ngokuthembekile ngokusemandleni awo, kungakhathaliseki izimo zokukhanyisa ezikhona.
