Txheej txheem cej luam ntawm UV Teeb Meters
Ultraviolet illuminance meter, tseem hu ua ultraviolet hluav taws xob ntsuas, ultraviolet siv lub ntsuas ntsuas, thiab lwm yam, feem ntau ntsuas cov hluav taws xob siv hluav taws xob ntawm ultraviolet rays, thiab yog siv hauv photochemistry, polymer cov khoom laus, kev kuaj pom qhov tsis zoo, ultraviolet lub teeb qhov chaw, cog cog, loj-scale. integrated circuit lithography thiab lwm qhov chaw UV hluav taws xob ntsuas kev ua haujlwm.
UV lub teeb ntsuas siv 35 lub taub hau sib txawv los ntsuas UVA, UVB, UVC, pom lub teeb thiab lub teeb infrared. Kev ntsuas wavelength ntawm lub ntsuas hluav taws xob ultraviolet tau muab faib ua UVA (320nm-380}nm), UVB (280nm-320}nm), UVC (200nm-280}nm), thiab qee cov khoom tuaj yeem ntes tau Muaj ntau yam bands, humanized lag luam, me me thiab saj zawg zog, tuaj yeem ua haujlwm nrog ib txhais tes, kev sojntsuam yog cais tawm ntawm lub cev, yooj yim thiab yooj yim, nrog kev nco tsis siv neeg, tuaj yeem khaws 20 cov ntaub ntawv, tuaj yeem siv dav hauv kev noj qab haus huv, kev kho mob, tshuaj lom neeg, kev tu cev, khoom noj khoom haus, hluav taws xob, aerospace thiab lwm yam lag luam, haum rau ultraviolet lub teeb, physiotherapy, fluorescence tsom xam, Kev ntsuas ntawm UV irradiance hauv UV lithography, kev kho dej, kev yug me nyuam thiab lwm yam.
Lub hauv paus ntsiab lus ntawm UV teeb meter
Ultraviolet illuminance meter yog ib qho cuab yeej tshwj xeeb hauv kev ntsuas luminosity thiab brightness. Nws yog ntsuas lub teeb siv (illuminance) yog qhov degree uas cov khoom yog illuminated, uas yog, qhov piv ntawm cov luminous flux tau nyob rau saum npoo ntawm cov khoom mus rau qhov chaw illuminated. Lub ntsuas hluav taws xob feem ntau yog tsim los ntawm selenium photocell lossis silicon photocell thiab microammeter. Lub hauv paus ntsiab lus yog: Photovoltaic cells yog cov khoom siv hluav taws xob photoelectric uas ncaj qha hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob. Thaum lub teeb tsoo rau saum npoo ntawm selenium photovoltaic cell, qhov teeb meem teeb dhau los ntawm cov hlau nyias zaj duab xis 4 thiab mus txog qhov sib cuam tshuam ntawm semiconductor selenium txheej 2 thiab cov hlau nyias zaj duab xis 4, tsim cov nyhuv photoelectric ntawm lub interface. Qhov loj ntawm qhov generated muaj peev xwm sib txawv muaj ib tug proportional kev sib raug zoo nrog lub illuminance ntawm lub teeb-tau txais nto ntawm lub photocell. Lub sijhawm no, yog tias ib qho kev sib txuas sab nraud txuas nrog, qhov tam sim no yuav ntws, thiab tus nqi tam sim no yuav qhia rau ntawm microammeter nrog qhov ntsuas ntawm lux (Lx). Qhov loj ntawm photocurrent nyob ntawm qhov siv ntawm qhov teeb meem teeb meem thiab qhov tsis kam nyob rau hauv Circuit Court. Lub illuminance meter muaj ib qho kev hloov khoom siv, yog li nws tuaj yeem ntsuas qhov siab illuminance lossis qis illuminance.
