395 nm vs . 365nm UV Teeb
Hauv qhov tshwj xeebUV teeb pom kev zookev ua lag luam, cov lus nug tshwm sim thiab tseem ceeb tshwm sim: Dab tsi yog qhov tiag -lub ntiaj teb sib txawv ntawm 395 nm thiab 365nm wavelengths? Thaum ob qho tib si poob rau hauv UV-Ib lub spectrum thiab siv rau cov teebmeem fluorescence, lawv cov kev sib txawv ntawm cov tsos thiab kev ua tau zoo yog qhov tseem ceeb. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev nrhiav cov khoom tsim nyog rau koj daim ntawv thov, txawm tias kev tshawb nrhiav cuav, kev kho vaj tse, lossis kev ua yeeb yam.
1. Qhov txawv ntawm qhov tseem ceeb: Qhov sib thooj rau qhov pom kev pom
Tus yuam sij rau kev nkag siab qhov sib txawv yog nyob rau hauv electromagnetic spectrum. Wavelength yog ntsuas hauv nanometers (nm), thiab tib neeg lub qhov muag feem ntau pom lub teeb ntawm li 380 nm (violet) txog 750 nm (liab).
395nm UV teeb:Qhov wavelength no ze heev rau qhov pom violet spectrum. Yog li ntawd, ib feem tseem ceeb ntawm nws lub teeb emitted yog perceived los ntawm tib neeg lub qhov muag raws li ib tugvivid, sib sib zog nqus ntshav los yog violet glow.
365nm UV teeb:Qhov no yog "qhov tob" UV wavelength, deb ntawm qhov pom spectrum. Lub siab -zoo 365 nm LED emits ntau dua pom lub teeb liab doog. Nws glow tshwm raws li ib tug heevdim, tsaus xiav lossis greyish-liab, tej zaum yuav luag tsis pom.
Vim li cas qhov no tseem ceeb?Lub teeb liab liab ntawm lub teeb 395 nm tsis yog lub teeb UV nws tus kheej - nws yog ib qho khoom lag luam. Qhov tseeb, siv tauUV-Ahluav taws xob uas ua rau fluorescence tsis pom. Nrog lub teeb 365 nm, koj tau txais kev cuam tshuam tsawg dua qhov pom kev thiab qhov feem ntau ntawm "active" UV tivthaiv uas ua rau cov khoom ci.
2. Visual Xim thiab "Perceived Brightness"
Qhov sib txawv tam sim ntawd tus neeg yuav khoom yuav pom yog xim ntawm lub teeb tawm los ntawm lub teeb nws tus kheej.

|
365nm ua |
Tsaus, dim xiav / ntshav lossis ze li tsaus |
Tswb los yog tsausraws li nws emits qhov pom tsawg kawg nkaus. |
Kev nkag siab tseem ceeb:Qhov no "pom ci ntsa iab" yog kev dag ntxias. Lub teeb 395nm zoo li ci ntsa iab rau koj ob lub qhov muag vim koj pom nws lub teeb pom kev zoo nkauj. Txawm li cas los xij, rau cov haujlwm uas vam khom raufluorescence(ua rau lwm yam khoom ci), 365nm wavelength feem ntau siv tau zoo dua, vim tias tsis tshua pom lub teeb los ntxuav tawm cov nyhuv ci.
3. "Lumen" tso zis: Ib qho kev ntsuas yuam kev rau UV
Nws yog ib qho tseem ceeb kom nkag siab tias tus qauvLumen (Lim)yog ib qho kev ntsuas tsis zoo rau kev ntsuas cov teeb pom kev ntshiab UV. Lub lumen yog ib chav ntsuas hnyav los ntawm qhov rhiab heev ntawm tib neeg lub qhov muag (cov lus teb photopic), uas yog tsawg heev nyob rau hauv UV ntau. Lub teeb 395nm yuav ib txwm muaj siab duantsuas lumen tso zisdua li lub teeb 365nm ntawm tib lub zog vim tias lub teeb 395nm nyob ze rau qhov peb qhov muag pom tau [1].
Ib qho kev ntsuas tseeb ntawm aUV teeb"lub zog" rau nws lub hom phiaj yogradiant flux,ntsuas hauvWatts (W)los yogmilliWatts (mW). Qhov no ntsuas tag nrho cov hluav taws xob kho qhov muag tawm, tsis hais nws qhov pom kev.
Rau Fluorescence Efficiency:Thaum ob lub wavelengths excite phosphors, 365nm feem ntau ua haujlwm zoo dua. Ntau cov khoom siv fluorescent muaj qhov siab tshaj plaws ntawm 350-370nm. Lub 365nm qhov chaw xa ntau ntawm nws lub zog ncaj qha mus rau qhov zoo tshaj plaws excitation band, ua rau muajbrighter thiab ntau vibrant fluorescencelos ntawm lub hom phiaj khoom, txawm tias lub teeb nws tus kheej zoo li dim [2].
4. Daim ntawv thov -Raws li cov lus pom zoo
Kev xaiv ntawm 395nm thiab 365nm yog nyob ntawm daim ntawv thov thiab qhov xav tau sib npaug ntawm cov nyhuv thiab tus nqi.
Xaiv 395nm UV Teeb rau:
Kev lom zem thiab Blacklight teebmeem:Party, clubs, thiab kho kom zoo nkauj teeb pom kev zoo. Lub zog ntshav liab ci yog ib feem ntawm qhov xav tau zoo nkauj.
Tus nqi -Sensitive Applications: 395nm LED teebfeem ntau tsis tshua kim los tsim thiab txaus rau cov haujlwm yooj yim xws li ua cov ntawv tshaj tawm yooj yim ci.
Cov ntawv thov uas qee qhov pom lub teeb tsis muaj teeb meem.
Xaiv 365nm UV Teeb rau:
Kev Tshawb Fawb Tseem Ceeb & Kev Tshawb Fawb Txog Kev Tshawb Fawb:Tshawb xyuas cov nyiaj cuav, cov ntaub ntawv, lossis pov thawj forensic. Lub teeb pom kev tsawg tsawg tiv thaiv qhov tsis pom kev, tso cai rau cov cim fluorescent tshwm nrog qhov sib txawv siab tshaj plaws thiab pom tseeb.
Industrial Curing:Qee cov nplaum thiab cov resins tau tsim los kho cov txiaj ntsig zoo tshaj plaws nrog kev sib sib zog nqus UV wavelengths.
Mineralogy thiab High -Quality Fluorescence Art:Txhawm rau ua tiav qhov ci ntsa iab tshaj plaws thiab qhov tseeb los ntawm cov zaub mov, cov nyiaj muas, lossis cov xim tsis muaj cov pa paug daj daj ntawm 395nm lub teeb.
Data Point:Ib txoj kev tshawb fawb sib piv cov fluorescence siv ntawm ib qho kev ruaj ntseg nta pom tau hais tias thaum illuminated los ntawm ib tug filtered 365nm qhov chaw, lub teeb liab - mus rau - suab nrov piv yog mus txog 50% siab dua thaum siv ib tug 395nm qhov chaw, vim qhov txo nyob rau hauv kev sib tw pom lub teeb [3].
Xaus: Pom vs. Ua
Qhov kev xaiv ntawm 395nm thiab 365nm yog kev lag luam -tawm ntawm kev nkag siab thiab kev ua haujlwm.
395nm uayog cov"saib-lub-teeb"kev xaiv. Lub teeb nws tus kheej zoo li ci ntsa iab thiab ntshav, ua rau nws haum rau kev lom zem thiab qis - daim ntawv thov nqi.
365nm uayog cov"saib-qhov -effect"kev xaiv. Lub teeb pom kev dim, tab sis nws muab lub teeb pom kev zoo UV uas feem ntau ua rau lub ntsej muag zoo dua thiab ci ntsa iab ntau dua, ua rau nws txoj kev xaiv rau kev siv tseem ceeb.
Thaum muab khoomUV teeb, tsis txhob dag los ntawm qhov pom ntshav ci. Rau siab - cov txiaj ntsig kev ua tau zoo, ua qhov tseem ceeb ntawm qhov tseeb 365nm nrog cov teeb pom kev tsawg tsawg.
