一,Yintoni ilensi ye-UV
Ilensi ye-UV, ekwaziwa ngokuba yilensi ye-ultraviolet, yilensi ye-optical eyenzelwe ngokukodwa ukudlulisa nokugxila ukukhanya kwe-ultraviolet (UV). Ukukhanya kwe-UV, okunee-wavelengths eziwela phakathi kwe-10 nm ukuya kwi-400 nm, kungaphaya kokukhanya okubonakalayo kwi-electromagnetic spectrum.
Iilensi ze-UV zisetyenziswa kakhulu kwizicelo ezifuna imifanekiso kunye nohlalutyo kuluhlu lwe-UV, njenge-fluorescence microscopy, i-UV spectroscopy, i-lithography, kunye nonxibelelwano lwe-UV. Ezi lensi ziyakwazi ukudlulisa ukukhanya kwe-UV ngokufunxa nokusasazeka okuncinci, okuvumela ukuba umfanekiso okanye uhlalutyo olucacileyo noluchanekileyo lweesampuli okanye izinto.
Uyilo kunye nokwenziwa kweelensi ze-UV kwahlukile kwezo zeelensi zokukhanya ezibonakalayo ngenxa yeempawu ezikhethekileyo zokukhanya kwe-UV. Izinto ezisetyenziselwa iilensi ze-UV zihlala ziquka i-fused silica, i-calcium fluoride (CaF2), kunye ne-magnesium fluoride (MgF2). Ezi zinto zinokudluliselwa okuphezulu kwe-UV kunye nokufunxwa okuphantsi kwe-UV, nto leyo eyenza ukuba zifaneleke ukusetyenziswa kwe-UV. Ukongeza, uyilo lwelensi kufuneka luqwalasele ukugqunywa okukhethekileyo kwe-optical ukuze kuphuculwe ukudluliselwa kwe-UV.
Iilensi ze-UV ziza ngeentlobo ezahlukeneyo, kuquka iilensi ze-plano-convex, biconvex, convex-concave, kunye ne-meniscus. Ukukhetha uhlobo lwelensi kunye neenkcukacha kuxhomekeke kwiimfuno ezithile zesicelo, ezifana nobude be-focal obufunekayo, indawo yokujonga, kunye nomgangatho womfanekiso.
二,TIimpawu kunye nokusetyenziswa kweelensi ze-UV
Kukho ezinye iimpawu kunye nokusetyenziswa kweelensi ze-UV：
Fukutya:
Ukuhanjiswa kwe-UV: Iilensi ze-UV zenzelwe ukuhambisa ukukhanya kwe-ultraviolet ngokunciphisa ukufunxa nokusasazeka. Zinokudlulisa okuphezulu kuluhlu lwamaza e-UV, ngesiqhelo phakathi kwe-200 nm ukuya kwi-400 nm.
Ukuphazamiseka okuphantsi: Iilensi ze-UV zenzelwe ukunciphisa ukuguquguquka kwe-chromatic kunye nezinye iintlobo zokuphazamiseka kwe-optical ukuqinisekisa ukwakheka komfanekiso ngokuchanekileyo kunye nohlalutyo kuluhlu lwe-UV.
Ukukhetha Izinto:Iilensi ze-UV zenziwe ngezinto ezinokuhanjiswa okuphezulu kwe-UV kunye nokufunxwa okuphantsi kwe-UV, ezifana ne-fused silica, i-calcium fluoride (CaF2), kunye ne-magnesium fluoride (MgF2).
Iingubo ezikhethekileyo: Iilensi ze-UV zihlala zifuna iingubo ezikhethekileyo zokukhanya ukuphucula ukuhanjiswa kwe-UV, ukunciphisa ukukhanya, kunye nokukhusela ilensi kwiimeko zokusingqongileyo.
Izicelo:
I-Mikroskopu yeFluorescence:Iilensi ze-UV zisetyenziswa kakhulu kwi-fluorescence microscopy ukuze kuvuselelwe kwaye kuqokelelwe imiqondiso ye-fluorescent ekhutshwa yi-fluorophores. Umthombo wokukhanya kwe-UV unceda ekuvuselelweni kwee-fluorescent probes ezithile, okuvumela ukuba kuthathwe imifanekiso eneenkcukacha zeesampuli zebhayoloji.
I-UV Spectroscopy:Iilensi ze-UV zisetyenziswa kwizicelo ze-spectroscopy ezifuna uhlalutyo lokufunxwa kwe-UV, ukukhutshwa kwayo, okanye ii-transmission spectra. Oku kuxabisekile kwiinkalo ezahlukeneyo zophando lwezenzululwazi, kubandakanya ikhemistri, ukujonga okusingqongileyo, kunye nesayensi yezinto.
I-Lithography:Iilensi ze-UV zizinto ezibalulekileyo kwi-photolithography, inkqubo esetyenziswa kwimveliso ye-semiconductor ukuprinta iipateni ezintsonkothileyo kwii-silicon wafers. Ukukhanya kwe-UV ngelensi kunceda ukuhambisa iipateni ezineenkcukacha ezininzi kwizinto ezikhusela ukukhanya.
Unxibelelwano lwe-UV:Iilensi ze-UV zisetyenziswa kwiinkqubo zonxibelelwano lwe-UV zokusasaza idatha engenazingcingo kwisithuba esifutshane. Ukukhanya kwe-UV kuvumela unxibelelwano oluhambelanayo, ngokuqhelekileyo kwiindawo zangaphandle, apho imiqobo efana nemithi nezakhiwo ingenasiphazamiso kangako xa ithelekiswa nokukhanya okubonakalayo.
Uhlalutyo lwe-Forensics kunye noXwebhu:Iilensi ze-UV zisetyenziswa kuvavanyo lwe-forensic kunye nohlalutyo lwamaxwebhu ukutyhila ulwazi olufihliweyo okanye olutshintshiweyo. Ukukhanya kwe-UV kunokutyhila izinto ezisebenza kwi-UV, kutyhile iimpawu zokhuseleko, okanye kufumane amaxwebhu angengowonyani.
Ukucoca nge-UV:Iilensi ze-UV zisetyenziswa kwizixhobo zokubulala iintsholongwane ze-UV ukubulala iintsholongwane emanzini, emoyeni, okanye kumphezulu. Ukukhanya kwe-UV okukhutshwa yilensi kusebenza kakhulu ekuthinteleni i-DNA yeentsholongwane, nto leyo eyenza ukuba ibe lukhetho oludumileyo lokunyanga amanzi kunye nokusetyenziswa kokubulala iintsholongwane.
Ngokubanzi, iilensi ze-UV zisetyenziswa kwiindawo ezahlukeneyo zesayensi, zoshishino, kunye nezobuchwepheshe apho imifanekiso ye-UV echanekileyo, uhlalutyo lwe-spectral, okanye ukuphathwa kokukhanya kwe-UV kubalulekile.
