Ultraviolet lub teeb meter yog ib qho cuab yeej tshwj xeeb rau kev ntsuas luminosity thiab brightness.
Nws yog los 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.
Ultraviolet light meter tseem hu ua ultraviolet light meter, ultraviolet siv meter, thiab lwm yam.;
Nws tsuas yog ntsuas qhov kev siv ntawm ultraviolet hluav taws xob;
Nws yog siv rau kev ntsuas hluav taws xob ultraviolet hauv thaj chaw ntawm photochemistry, cov khoom siv polymer aging, nrhiav pom qhov tsis haum, ultraviolet lub teeb qhov chaw, cog cog, loj-scale integrated circuit lithography, thiab lwm yam.
Lub hauv paus ntsiab lus ntawm UV teeb meter yog:
Photovoltaic cells yog cov khoom siv hluav taws xob 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 photocell, qhov teeb meem tshwm sim dhau los ntawm cov yeeb yaj kiab hlau 4 thiab mus txog qhov sib cuam tshuam ntawm cov semiconductor selenium txheej 2 thiab cov yeeb yaj kiab hlau 4, thiab cov nyhuv photoelectric yog tsim los ntawm lub interface.
Qhov loj ntawm qhov muaj peev xwm sib txawv yog proportional rau lub illuminance ntawm lub teeb-tau txais nto ntawm lub cell photovoltaic.
Lub sijhawm no, yog tias ib qho kev sib txuas sab nraud txuas nrog, qhov tam sim no yuav ntws los ntawm, thiab tus nqi tam sim no yuav qhia rau ntawm microammeter nrog lux (Lx) raws li qhov ntsuas.
Qhov loj ntawm photocurrent nyob ntawm qhov siv ntawm qhov teeb meem teeb meem thiab qhov tsis kam nyob rau hauv lub voj.
Lub illuminance meter muaj ib qho kev hloov khoom siv, yog li nws tuaj yeem ntsuas qhov siab illuminance thiab qis illuminance.
