Iilensi ze-UV, njengoko igama lisitsho, ziilensi ezinokusebenza phantsi kokukhanya kwe-ultraviolet. Umphezulu weelensi ezinjalo uhlala ugqunywe ngengubo ekhethekileyo enokufunxa okanye ibonise ukukhanya kwe-ultraviolet, ngaloo ndlela ithintela ukukhanya kwe-ultraviolet ekukhanyeni ngokuthe ngqo kwisenzi somfanekiso okanye ifilimu.
1,Iimpawu eziphambili zeelensi ze-UV
Ilensi ye-UV yilensi ekhethekileyo enokusinceda "sibone" ihlabathi esingenakulibona ngokuqhelekileyo. Ngamafutshane, iilensi ze-UV zineempawu eziphambili ezilandelayo:
(1)Iyakwazi ukucoca imisebe ye-ultraviolet nokususa iziphumo ezibangelwa yimisebe ye-ultraviolet
Ngenxa yomgaqo wayo wokwenziwa, iilensi ze-UV zinomsebenzi othile wokucoca imitha ye-ultraviolet. Zingahluza inxalenye yemitha ye-ultraviolet (ngokuvamile, zihluza imitha ye-ultraviolet ephakathi kwe-300-400nm). Kwangaxeshanye, zinokunciphisa kwaye zisuse ukufiphala komfanekiso kunye nokusasazwa okuluhlaza okwesibhakabhaka okubangelwa yimitha ye-ultraviolet emoyeni okanye ukukhanya kwelanga okugqithisileyo.
(2)Yenziwe ngezinto ezikhethekileyo
Ngenxa yokuba iglasi eqhelekileyo kunye neplastiki azikwazi ukudlulisa ukukhanya kwe-ultraviolet, iilensi ze-UV zihlala zenziwe nge-quartz okanye izinto ezithile ze-optical.
(3)Iyakwazi ukudlulisa ukukhanya kwe-ultraviolet kunye nokudlulisa imisebe ye-ultraviolet
Iilensi ze-UVidlulisela ukukhanya kwe-ultraviolet, okukukhanya okunobude bomda obuphakathi kwe-10-400nm. Oku kukhanya akubonakali emehlweni omntu kodwa kunokubanjwa yikhamera ye-UV.
Ukukhanya kwe-ultraviolet akubonakali emehlweni omntu
(4)Yiba neemfuno ezithile zokusingqongileyo
Iilensi ze-UV zihlala zifuna ukusetyenziswa kwiindawo ezithile. Umzekelo, ezinye iilensi ze-UV zinokusebenza ngokufanelekileyo kuphela kwindawo ngaphandle kokuphazamiseka kokukhanya okubonakalayo okanye ukukhanya kwe-infrared.
(5)Ilensi ibiza kakhulu
Ekubeni ukwenziwa kweelensi ze-UV kufuna izixhobo ezikhethekileyo kunye neenkqubo ezichanekileyo zokuvelisa, ezi lensi zihlala zibiza kakhulu kuneelensi eziqhelekileyo kwaye kunzima ukuba abafoti abaqhelekileyo bazisebenzise.
(6)Iimeko zesicelo esikhethekileyo
Iindlela zokusetyenziswa kweelensi ze-ultraviolet nazo zikhethekile. Zihlala zisetyenziswa kuphando lwezenzululwazi, uphando lwendawo yolwaphulo-mthetho, ukufunyanwa kwemali engeyonyani, imifanekiso yezonyango kunye neminye imimandla.
2,Amanyathelo okuphepha xa usebenzisa iilensi ze-UV
Ngenxa yeempawu ezikhethekileyo zelensi, kufuneka kuthathwe amanyathelo athile okhuseleko xa usebenzisaIlensi ye-UV:
(1) Lumka ungachukumisi umphezulu welensi ngeminwe yakho. Ukubila kunye negrisi kunokuyidlalisa ilensi kwaye kuyenze ingasetyenziswa.
(2) Lumka ungadubuli ngemithombo yokukhanya enamandla njengesixhobo, njengokudubula ngqo ukuphuma kwelanga okanye ukutshona kwelanga, kungenjalo ilensi ingonakalisa.
Kuphephe ukudubula elangeni ngqo
(3) Lumka ungatshintshi iilensi rhoqo kwindawo enotshintsho olukhulu lokukhanya ukuze uthintele ukwakheka kombungu ngaphakathi kwilensi.
(4)Qaphela: Ukuba amanzi angena kwilensi, yicime ngoko nangoko i-power supply uze ufune ukulungiswa kobuchwephesha. Musa ukuzama ukuyivula lensi uze uyicoce ngokwakho.
(5) Lumka ukufaka nokusebenzisa ilensi ngokuchanekileyo, kwaye uphephe ukusebenzisa amandla agqithisileyo, anokubangela ukuguguleka kwelensi okanye ujongano lwekhamera.
Iingcinga Zokugqibela:
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
