一,Iyini i-lens ye-UV
Ilensi ye-UV, eyaziwa nangokuthi ilensi ye-ultraviolet, ilensi yokubona eklanyelwe ukudlulisa nokugxilisa ukukhanya kwe-ultraviolet (UV). Ukukhanya kwe-UV, okunamaza amaza awela phakathi kuka-10 nm kuya ku-400 nm, kungaphezu kobubanzi bokukhanya okubonakalayo ku-spectrum kagesi.
Amalensi e-UV avame ukusetshenziswa ezinhlelweni ezidinga ukuthwebula izithombe nokuhlaziya ebangeni le-UV, njenge-fluorescence microscopy, i-UV spectroscopy, i-lithography, nokuxhumana kwe-UV. Lawa ma-lens ayakwazi ukudlulisa ukukhanya kwe-UV ngokumunca okuncane nokuhlakazeka, okuvumela ukuthwebula okucacile nokunembile noma ukuhlaziya amasampula noma izinto.
Ukuklanywa nokwakhiwa kwamalensi e-UV kuhlukile kulawo amalensi okukhanya abonakalayo ngenxa yezakhiwo eziyingqayizivele zokukhanya kwe-UV. Izinto ezisetshenziselwa amalensi e-UV ngokuvamile zihlanganisa i-silica ehlanganisiwe, i-calcium fluoride (CaF2), ne-magnesium fluoride (MgF2). Lezi zinto zinokudluliselwa kwe-UV ephezulu kanye nokumuncwa okuphansi kwe-UV, okuzenza zilungele ukusetshenziswa kwe-UV. Ukwengeza, idizayini yelensi idinga ukucabangela ukumbozwa okukhethekile okubonakalayo ukuze kuthuthukiswe ukudluliswa kwe-UV.
Amalensi e-UV eza ngezinhlobo ezahlukene, okuhlanganisa i-plano-convex, i-biconvex, i-convex-concave, namalensi e-meniscus. Ukukhethwa kohlobo lwelensi nokucaciswa kuncike ezindingweni ezithile zohlelo lokusebenza, njengobude bokugxila obufunekayo, indawo yokubuka, nekhwalithi yesithombe.
二,Tizici kanye nokusetshenziswa kwamalensi e-UV
Kunezici ezithile kanye nokusetshenziswa kwamalensi e-UV:
Fizilwane:
I-UV Transmittance: Amalensi e-UV aklanyelwe ukudlulisa ukukhanya kwe-ultraviolet ngokumunca okuncane nokuhlakazeka. Zinokudluliselwa okuphezulu ebangeni le-UV wavelength, ngokuvamile phakathi kuka-200 nm kuya ku-400 nm.
I-Low Aberration: Amalensi e-UV aklanyelwe ukunciphisa ukuphuma kwe-chromatic nezinye izinhlobo zokuhlanekezelwa kokubona ukuze kuqinisekiswe ukwakheka nokuhlaziywa kwesithombe okunembile ebangeni le-UV.
Ukukhetha Okubalulekile:Amalensi e-UV akhiwe ngezinto ezinokudluliswa kwe-UV okuphezulu nokumuncwa kwe-UV okuphansi, njenge-silica ehlanganisiwe, i-calcium fluoride (CaF2), ne-magnesium fluoride (MgF2).
Izingubo Ezikhethekile: Amalensi e-UV ngokuvamile adinga ama-optical coating akhethekile ukuze athuthukise ukudluliswa kwe-UV, anciphise ukubonakaliswa, futhi avikele ilensi ezicini zemvelo.
Izicelo:
I-Fluorescence Microscopy:Amalensi e-UV avame ukusetshenziswa ku-fluorescence microscopy ukuze ajabule futhi aqoqe amasiginali we-fluorescent akhishwa ama-fluorophores. Umthombo wokukhanya we-UV usiza ekusaseni kwama-fluorescent probes athile, okuvumela ukuthwebula izithombe ezinemininingwane yamasampuli ebhayoloji.
UV Spectroscopy:Amalensi e-UV asetshenziswa ezinhlelweni ze-spectroscopy ezidinga ukuhlaziya ukumuncwa kwe-UV, ukukhishwa, noma i-spectra yokudlulisela. Lokhu kubalulekile emikhakheni eyahlukene yocwaningo lwesayensi, okuhlanganisa amakhemikhali, ukuqapha imvelo, kanye nesayensi yezinto.
I-Lithography:Amalensi e-UV ayizingxenye ezibalulekile ku-photolithography, inqubo esetshenziswa ekwenziweni kwe-semiconductor ukuphrinta amaphethini ayinkimbinkimbi kumawafa e-silicon. Ukuchayeka kokukhanya kwe-UV ngelensi kusiza ukudlulisa amaphethini anemininingwane eminingi kokubalulekile kwe-photoresist.
Ukuxhumana kwe-UV:Amalensi e-UV asetshenziswa ezinhlelweni zokuxhumana ze-UV ekudluliselweni kwedatha engenantambo yebanga elifushane. Ukukhanya kwe-UV kunika amandla ukuxhumana komugqa wokubona, ngokuvamile ezindaweni zokusebenza zangaphandle, lapho izithiyo ezifana nezihlahla nezakhiwo zinokuphazamiseka okuncane uma kuqhathaniswa nokukhanya okubonakalayo.
I-Forensics nokuhlaziywa kwedokhumenti:Amalensi e-UV asetshenziswa ekuhlolweni kwe-forensic kanye nokuhlaziywa kwemibhalo ukuze kwembulwe imininingwane efihliwe noma eshintshiwe. Ukukhanya kwe-UV kungembula izinto ezisebenza nge-UV, kuveze izici zokuphepha, noma kubone amadokhumenti omgunyathi.
Ukuvalwa kwe-UV:Amalensi e-UV asetshenziswa emishinini yokuvala inzalo ye-UV ukuze kubulawe amagciwane emanzini, umoya, noma izindawo ezingaphezulu. Ukukhanya kwe-UV okukhishwa nge-lens kuphumelela kakhulu ekwenzeni i-DNA yama-microorganisms ingabi namandla, okuyenza ibe ukukhetha okudumile ekuhlanzweni kwamanzi nasekubulaleni inzalo.
Sekukonke, amalensi e-UV athola ukusebenza emikhakheni ebanzi yesayensi, yezimboni, nezobuchwepheshe lapho ukuthwebula kwe-UV okunembile, ukuhlaziya okubonakalayo, noma ukukhohlisa kokukhanya kwe-UV kubalulekile.
