Amalensi e-UV, njengoba igama lisho, amalensi angasebenza ngaphansi kokukhanya kwe-ultraviolet. Ubuso bamalensi anjalo buvame ukumbozwa ngesembozo esikhethekile esingamunca noma sibonise ukukhanya kwe-ultraviolet, ngaleyo ndlela sivimbele ukukhanya kwe-ultraviolet ekukhanyeni ngqo ku-sensor yesithombe noma ifilimu.
1,Izici eziyinhloko zamalensi e-UV
Ilensi ye-UV ilensi ekhethekile kakhulu engasisiza "sibone" umhlaba esingakwazi ukuwubona ngokujwayelekile. Ngamafuphi, amalensi e-UV anezici ezilandelayo eziyinhloko:
(1)Iyakwazi ukuhlunga imisebe ye-ultraviolet futhi isuse imiphumela ebangelwa imisebe ye-ultraviolet
Ngenxa yesimiso sayo sokukhiqiza, amalensi e-UV anomsebenzi othile wokuhlunga imisebe ye-ultraviolet. Angahlunga ingxenye yemisebe ye-ultraviolet (ngokuvamile, ahlunga imisebe ye-ultraviolet ephakathi kuka-300-400nm). Ngesikhathi esifanayo, anganciphisa futhi aqede ngempumelelo ukufiphala kwesithombe kanye nokusabalala okuluhlaza okwesibhakabhaka okubangelwa imisebe ye-ultraviolet emkhathini noma ukukhanya kwelanga okweqile.
(2)Kwenziwe ngezinto ezikhethekile
Ngenxa yokuthi ingilazi evamile nepulasitiki azikwazi ukudlulisa ukukhanya kwe-ultraviolet, amalensi e-UV ngokuvamile enziwa nge-quartz noma izinto ezithile zokukhanya.
(3)Iyakwazi ukudlulisa ukukhanya kwe-ultraviolet nokudlulisa imisebe ye-ultraviolet
Amalensi e-UVidlulisela ukukhanya kwe-ultraviolet, okuwukukhanya okunobude be-wavelength obuphakathi kuka-10-400nm. Lokhu kukhanya akubonakali emehlweni omuntu kodwa kungathathwa yikhamera ye-UV.

(4)Yiba nezidingo ezithile zemvelo
Amalensi e-UV ngokuvamile adinga ukusetshenziswa ezindaweni ezithile. Isibonelo, amanye amalensi e-UV angasebenza kahle kuphela endaweni ngaphandle kokuphazamiseka kokukhanya okubonakalayo noma ukukhanya kwe-infrared.
(5)Ilensi iyabiza kakhulu
Njengoba ukukhiqizwa kwamalensi e-UV kudinga izinto ezikhethekile kanye nezinqubo zokukhiqiza ezinembile, lawa malensi ngokuvamile abiza kakhulu kunamalensi avamile futhi kunzima ngabathwebuli bezithombe abavamile ukuwasebenzisa.
(6)Izimo ezikhethekile zohlelo lokusebenza
Izimo zokusetshenziswa kwamalensi e-ultraviolet nazo zikhethekile impela. Ngokuvamile zisetshenziswa ocwaningweni lwesayensi, ophenyweni lwendawo yobugebengu, ekutholakaleni kwemali mbumbulu, ekuthathweni kwezithombe zezokwelapha kanye neminye imikhakha.
2,Izinyathelo zokuphepha zokusebenzisa amalensi e-UV
Ngenxa yezici ezikhethekile zelensi, kufanele kuthathwe izinyathelo zokuphepha ezithile uma usebenzisaIlensi ye-UV:
(1) Qaphela ukuthi ugweme ukuthinta ubuso belensi ngeminwe yakho. Ukujuluka kanye namafutha kungase kugqwalise ilensi futhi kwenze ingasetshenziswa.
(2) Qaphela ukuthi ungadubuli ngemithombo yokukhanya enamandla njengesihloko, njengokudubula ngqo ukuphuma kwelanga noma ukushona kwelanga, ngaphandle kwalokho ilensi ingase yonakale.
Gwema ukudubula elangeni eliqondile
(3) Qaphela ukuthi ugweme ukushintsha amalensi njalo endaweni enezinguquko ezinkulu zokukhanya ukuze uvimbele ukwakheka kwesikhunta ngaphakathi kwelensi.
(4)Qaphela: Uma amanzi engena kulensi, nqamula ngokushesha ugesi bese ucela ukulungiswa kochwepheshe. Ungazami ukuvula ilensi bese uyihlanza wena.
(5) Qaphela ukufaka nokusebenzisa ilensi ngendlela efanele, futhi ugweme ukusebenzisa amandla amaningi, okungase kubangele ukuguguleka kwelensi noma isikhombikubona sekhamera.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
