一,Iyini ilensi ye-UV
Ilensi ye-UV, eyaziwa nangokuthi ilensi ye-ultraviolet, ilensi yokukhanya eyenzelwe ngqo ukudlulisa nokugxila ukukhanya kwe-ultraviolet (UV). Ukukhanya kwe-UV, okunama-wavelength aphakathi kuka-10 nm kuya ku-400 nm, kungaphezu kokukhanya okubonakalayo ku-spectrum ye-electromagnetic.
Amalensi e-UV avame ukusetshenziswa ezinhlelweni zokusebenza ezidinga ukuthwebula izithombe nokuhlaziywa kububanzi be-UV, njenge-fluorescence microscopy, i-UV spectroscopy, i-lithography, kanye nokuxhumana kwe-UV. Lawa malensi ayakwazi ukudlulisa ukukhanya kwe-UV ngokumunca okuncane nokusabalala, okuvumela ukuthwebula izithombe noma ukuhlaziywa kwamasampula noma izinto okucacile nokunembile.
Ukwakheka kanye nokukhiqizwa kwamalensi e-UV kuhlukile kulawo amalensi okukhanya abonakalayo ngenxa yezakhiwo ezihlukile zokukhanya kwe-UV. Izinto ezisetshenziswa kumalensi e-UV zivame ukufaka i-fused silica, i-calcium fluoride (CaF2), kanye ne-magnesium fluoride (MgF2). Lezi zinto zinokudluliswa okuphezulu kwe-UV kanye nokumuncwa kwe-UV okuphansi, okwenza zifanele ukusetshenziswa kwe-UV. Ngaphezu kwalokho, ukwakheka kwamalensi kudinga ukucabangela izembozo ezikhethekile zokukhanya ukuze kuthuthukiswe ukudluliswa kwe-UV.
Amalensi e-UV afika ngezinhlobo ezahlukene, kufaka phakathi amalensi e-plano-convex, biconvex, convex-concave, kanye ne-meniscus. Ukukhetha uhlobo lwelensi kanye nokucaciswa kuncike ezidingweni ezithile zohlelo lokusebenza, njengobude obufunwayo bokugxila, indawo yokubuka, kanye nekhwalithi yesithombe.
二,Tizici kanye nokusetshenziswa kwamalensi e-UV
Kukhona ezinye izici kanye nokusetshenziswa kwamalensi e-UV：
Fukudla:
Ukudluliswa kwe-UV: Amalensi e-UV aklanyelwe ukudlulisa ukukhanya kwe-ultraviolet ngokumunca okuncane nokusabalala. Ane-transmittance ephezulu ebangeni lamaza e-UV, ngokuvamile aphakathi kuka-200 nm kuya ku-400 nm.
Ukuphambuka Okuphansi: Amalensi e-UV aklanyelwe ukunciphisa ukuphambuka kwe-chromatic kanye nezinye izinhlobo zokuphambuka kokukhanya ukuqinisekisa ukwakheka kwesithombe okunembile kanye nokuhlaziywa kobubanzi be-UV.
Ukukhethwa Kwezinto:Amalensi e-UV enziwe ngezinto ezinokudluliswa okuphezulu kwe-UV kanye nokumuncwa okuphansi kwe-UV, njenge-fused silica, i-calcium fluoride (CaF2), kanye ne-magnesium fluoride (MgF2).
Izembozo Ezikhethekile: Amalensi e-UV avame ukudinga izembozo ezikhethekile zokukhanya ukuze kuthuthukiswe ukudluliselwa kwe-UV, kuncishiswe ukubonakaliswa, futhi kuvikelwe ilensi ezicini zemvelo.
Izicelo:
I-Microscopy ye-Fluorescence:Amalensi e-UV avame ukusetshenziswa ku-microscopy ye-fluorescence ukuze kushukunyiswe futhi kuqoqwe izimpawu ze-fluorescent ezikhishwa yi-fluorophores. Umthombo wokukhanya kwe-UV usiza ekushukumiseni ama-probe athile e-fluorescent, okuvumela ukuthwebula izithombe ezinemininingwane yamasampula ebhayoloji.
I-UV Spectroscopy:Amalensi e-UV asetshenziswa ezinhlelweni ze-spectroscopy ezidinga ukuhlaziywa kokumuncwa kwe-UV, ukukhishwa kwayo, noma ama-spectra okudlulisela. Lokhu kuwusizo emikhakheni eyahlukene yocwaningo lwesayensi, okuhlanganisa i-chemistry, ukuqapha imvelo, kanye nesayensi yezinto ezibonakalayo.
I-Lithography:Amalensi e-UV ayizingxenye ezibalulekile ku-photolithography, inqubo esetshenziswa ekukhiqizweni kwe-semiconductor ukuphrinta amaphethini ayinkimbinkimbi kuma-silicon wafers. Ukuvezwa kokukhanya kwe-UV ngelensi kusiza ukudlulisa amaphethini anemininingwane eminingi ezintweni ezivikela ukukhanya.
Ukuxhumana kwe-UV:Amalensi e-UV asetshenziswa ezinhlelweni zokuxhumana ze-UV ukuze kudluliselwe idatha engenantambo yebanga elifushane. Ukukhanya kwe-UV kwenza ukuxhumana komugqa wokubona, ngokuvamile ezindaweni zokusebenza zangaphandle, lapho izithiyo ezifana nezihlahla nezakhiwo zingenakuphazamiseka okuncane uma kuqhathaniswa nokukhanya okubonakalayo.
Ukuhlolwa Kwezinsolo Nokuhlaziywa Kwemibhalo:Amalensi e-UV asetshenziswa ekuhlolweni kwezomthetho kanye nasekuhlaziyweni kwemibhalo ukuze kwembulwe ulwazi olufihliwe noma olushintshiwe. Ukukhanya kwe-UV kungaveza izinto ezisebenza nge-UV, kwembulwe izici zokuphepha, noma kutholakale amadokhumenti angewona.
Ukuhlanza nge-UV:Amalensi e-UV asetshenziswa kumadivayisi okubulala amagciwane e-UV ukuze abulale amagciwane emanzini, emoyeni, noma ezindaweni. Ukukhanya kwe-UV okukhishwa ngaleli kusebenza kahle kakhulu ekuqedeni i-DNA yama-microorganisms, okwenza kube ukukhetha okuthandwayo kokwelashwa kwamanzi kanye nokusetshenziswa kokubulala amagciwane.
Sekukonke, amalensi e-UV asetshenziswa emikhakheni eminingi yesayensi, yezimboni, kanye nezobuchwepheshe lapho ukuthwebula izithombe ze-UV okunembile, ukuhlaziywa kwe-spectral, noma ukuphathwa kokukhanya kwe-UV kubalulekile khona.
