ib ,Lub lens UV yog dab tsi
Lub lens UV, tseem hu ua lub lens ultraviolet, yog lub lens kho qhov muag uas tsim tshwj xeeb los xa thiab tsom lub teeb ultraviolet (UV). Lub teeb UV, nrog rau qhov ntev ntawm 10 nm txog 400 nm, yog dhau ntawm qhov ntau ntawm lub teeb pom kev ntawm lub spectrum electromagnetic.
Cov tsom iav UV feem ntau siv rau hauv cov ntawv thov uas xav tau kev thaij duab thiab kev tshuaj xyuas hauv UV, xws li fluorescence microscopy, UV spectroscopy, lithography, thiab UV kev sib txuas lus. Cov tsom iav no muaj peev xwm xa tau lub teeb UV nrog qhov nqus thiab tawg tsawg kawg nkaus, ua rau muaj kev thaij duab meej thiab raug lossis kev tshuaj xyuas cov qauv lossis cov khoom.
Kev tsim thiab kev tsim cov iav UV txawv ntawm cov iav pom kev vim yog cov yam ntxwv tshwj xeeb ntawm lub teeb UV. Cov ntaub ntawv siv rau cov iav UV feem ntau suav nrog fused silica, calcium fluoride (CaF2), thiab magnesium fluoride (MgF2). Cov ntaub ntawv no muaj kev xa tawm UV siab thiab kev nqus UV qis, ua rau lawv haum rau kev siv UV. Tsis tas li ntawd, kev tsim cov iav yuav tsum xav txog cov txheej txheem kho qhov muag tshwj xeeb kom txhim kho kev xa tawm UV ntxiv.
Cov iav UV muaj ntau hom, suav nrog cov iav plano-convex, biconvex, convex-concave, thiab meniscus. Kev xaiv hom iav thiab cov lus qhia tshwj xeeb nyob ntawm qhov xav tau ntawm daim ntawv thov, xws li qhov ntev ntawm lub lens, qhov pom kev, thiab qhov zoo ntawm daim duab.
二,Tnws cov yam ntxwv thiab kev siv ntawm UV lenses
Muaj qee qhov nta thiab daim ntawv thov ntawm UV lenses：
Fcov yam ntxwv:
Kev Kis UV: Cov tsom iav UV yog tsim los xa cov teeb ultraviolet nrog qhov nqus thiab tawg tsawg kawg nkaus. Lawv muaj kev xa hluav taws xob siab hauv qhov ntau ntawm UV wavelength, feem ntau ntawm 200 nm txog 400 nm.
Kev Hloov Pauv Tsawg: Cov iav UV yog tsim los txo cov chromatic aberration thiab lwm yam kev cuam tshuam ntawm qhov muag kom ntseeg tau tias muaj cov duab raug thiab kev tshuaj xyuas hauv UV ntau yam.
Kev Xaiv Khoom Siv:Cov iav UV yog tsim los ntawm cov ntaub ntawv uas muaj kev xa tawm UV siab thiab kev nqus UV tsawg, xws li fused silica, calcium fluoride (CaF2), thiab magnesium fluoride (MgF2).
Cov Txheej Txheem Tshwj Xeeb: Cov tsom iav UV feem ntau xav tau cov txheej txheem kho qhov muag tshwj xeeb los txhim kho kev xa tawm UV, txo cov kev cuam tshuam, thiab tiv thaiv lub lens los ntawm cov yam ntxwv ib puag ncig.
Cov ntawv thov:
Kev Siv Lub Tshuab Microscopy Fluorescence:Cov iav UV feem ntau siv rau hauv kev siv lub tshuab fluorescence microscopy los ua kom muaj zog thiab sau cov teeb liab fluorescent uas cov fluorophores tso tawm. Lub teeb UV pab txhawb cov khoom siv fluorescent probes tshwj xeeb, ua rau pom cov duab ntxaws ntxaws ntawm cov qauv tsiaj txhu.
UV Spectroscopy:Cov iav UV siv rau hauv cov ntawv thov spectroscopy uas xav tau kev tshuaj xyuas ntawm UV absorption, emission, lossis transmission spectra. Qhov no muaj txiaj ntsig zoo rau ntau yam kev tshawb fawb, suav nrog chemistry, kev saib xyuas ib puag ncig, thiab cov ntaub ntawv science.
Kev kos duab:Cov iav UV yog cov khoom tseem ceeb hauv kev thaij duab photolithography, ib qho txheej txheem siv hauv kev tsim khoom semiconductor los luam cov qauv nyuaj rau ntawm cov silicon wafers. Kev raug lub teeb UV los ntawm lub lens pab xa cov qauv ntxaws ntxaws heev rau ntawm cov khoom siv photoresist.
Kev Sib Txuas Lus UV:Cov iav UV siv rau hauv cov kab ke sib txuas lus UV rau kev xa cov ntaub ntawv wireless luv luv. Lub teeb UV ua rau muaj kev sib txuas lus pom kev, feem ntau yog siv rau sab nraum zoov, qhov twg cov teeb meem xws li ntoo thiab tsev muaj kev cuam tshuam tsawg dua piv rau lub teeb pom kev.
Kev Tshawb Fawb Txog Kev Ua Txhaum Cai thiab Kev Tshawb Fawb Txog Cov Ntaub Ntawv:Cov iav UV siv rau hauv kev tshuaj xyuas thiab kev tshuaj xyuas cov ntaub ntawv kom pom cov ntaub ntawv zais lossis hloov pauv. Lub teeb UV tuaj yeem tshawb pom cov tshuaj uas ua rau UV ua haujlwm, qhia txog cov yam ntxwv kev ruaj ntseg, lossis nrhiav cov ntaub ntawv cuav.
Kev Ua Kom Tsis Muaj Kab Mob UV:Cov tsom iav UV siv rau hauv cov khoom siv tua kab mob UV los tua kab mob hauv dej, huab cua, lossis qhov chaw. Lub teeb UV uas tso tawm los ntawm lub tsom iav muaj txiaj ntsig zoo heev rau kev ua kom cov DNA ntawm cov kab mob me me tsis muaj zog, ua rau nws yog qhov kev xaiv nrov rau kev kho dej thiab kev tua kab mob.
Zuag qhia tag nrho, UV lo ntsiab muag pom tau tias siv tau rau ntau yam kev tshawb fawb, kev lag luam, thiab kev siv tshuab uas qhov tseeb UV imaging, spectral analysis, lossis UV light manipulation yog qhov tseem ceeb.
