Amalensi we-UV, njengoba igama lisho, amalensi angasebenza ngaphansi kokukhanya kwe-ultraviolet. Ingaphezulu lamalensi anjalo livame ukuhlanganiswa ngenhlamba ekhethekile engadonsa noma ibonise ukukhanya kwe-ultraviolet, ngaleyo ndlela kuvikele ukukhanya kwe-ultraviolet kusuka ekukhanyisweni kwesithombe noma ifilimu.
1,Izici eziyinhloko ze-UV lens
Ilensi ye-UV iyilensi ekhetheke kakhulu engasisiza ukuba 'sibone' umhlaba esingeke sivame ukubona. Ukufingqa, amalensi we-UV anezici eziphambili ezilandelayo:
(1)Uyakwazi ukuhlunga imisebe ye-ultraviolet futhi ususe imiphumela ebangelwa imisebe ye-ultraviolet
Ngenxa yomgomo wayo wokukhiqiza, amalensi we-UV anomsebenzi othile wokuhlunga wemisebe ye-ultraviolet. Bangakwazi ukuhlunga ingxenye yemisebe ye-ultraviolet (ngokuvamile ekhuluma, bahlunga imisebe ye-ultraviolet phakathi kuka-300-400nm). Ngasikhathi sinye, banganciphisa ngempumelelo futhi baqede ukufiphala kwesithombe kanye nokuhlakazeka okuluhlaza okwesibhakabhaka okubangelwa imisebe ye-ultraviolet emkhathini noma elanga elangeni.
(2)Yenziwe ngezinto ezikhethekile
Ngoba ingilazi evamile nepulasitiki ngeke kudlulise ukuhambisa ukukhanya kwe-ultraviolet, amalensi we-UV ngokuvamile enziwa nge-quartz noma ngezinto ezithile ezibonakalayo.
(3)Uyakwazi ukudlulisa ukukhanya kwe-ultraviolet futhi udlulise imisebe ye-ultraviolet
Amalensi we-UVDlulisa ukukhanya kwe-ultraviolet, okulula nge-wavelength phakathi kuka-10-400mm. Lokhu kukhanya akubonakali esweni lomuntu kodwa kungadonswa yikhamera ye-UV.
Ukukhanya kwe-ultraviolet akubonakali ngamehlo somuntu
(4)Ube nezidingo ezithile zemvelo
Amalensi we-UV ajwayele ukusetshenziselwa ezindaweni ezithile. Isibonelo, amanye amalensi e-UV angasebenza kahle endaweni engenayo ngaphandle kokuphazamiseka kokukhanya okubonakalayo noma okukhanyayo.
(5)Ilensi iyabiza
Njengoba ukwakhiwa kwamalensi we-UV kudinga izinto ezikhethekile nezinqubo zokukhiqiza eziqondile, la ma-lens ajwayele ukubiza kakhulu kunama-lens ajwayelekile futhi anzima ukuthi abathwebuli bezithombe abajwayelekile basebenzise.
(6)Izimo ezikhethekile zesicelo
Izimo zohlelo lokusebenza ze-Ultraviolet lens nazo zikhethekile. Imvamisa isetshenziswa ocwaningweni lwesayensi, uphenyo lwesehlakalo sobugebengu, ukutholwa kwe-reatfeit basengnote, ukucabanga kwemvelo kanye nezinye izinkambu.
2,Izindlela zokuphepha zokusebenzisa ama-UV lens
Ngenxa yezici ezikhethekile zelensi, ezinye izinyathelo zokuphepha kufanele zithathwe lapho zisebenzisaIlensi ye-UV:
(1) Qaphela ukugwema ukuthinta indawo ye-lens ngeminwe yakho. Ukujuluka namafutha kungalungisa ilensi futhi kwenze kungabonakali.
(2) Qikelela ukuthi ungadubuli ngemithombo eqinile yokukhanya njengesihloko, njengokudubula ngokuqondile ukuphuma kwelanga noma ukushona kwelanga, ngaphandle kwalokho amalensi angalimala.
Gwema ukudubula ngokukhanya kwelanga okuqondile
.
(4) Qaphela: Uma amanzi engena ku-lens, anqunywe ngokushesha ukunikezwa kwamandla futhi afune ukulungiswa kochwepheshe. Ungazami ukuvula ilensi futhi uzihlanze.
(5) Qikelela ukufaka futhi usebenzise i-lens ngendlela efanele, futhi uvikele ukusebenzisa amandla ngokweqile, okungadala ukugqoka nokuklebhula ku-lens noma isikhombimsebenzisi sekhamera.
Imicabango yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukahlukene zamalensi zokubhekwa, ukuskena, ama-drones, ekhaya elihlakaniphile, noma okunye ukusetshenziswa, sinakho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngama-lens ethu nezinye izesekeli.
