Thaum lub teeb teeb hla dhau ntawm cov qauv xim, lub zog nrog ib lub wavelength tshwj xeeb yog absorbed los ntawm cov tshuaj ntsuam xyuas. Lub photometer txiav txim siab cov xim ntawm cov qauv los ntawm kev ntsuas qhov sib kis lossis nqus ntawm lub teeb ntawm qhov wavelength(hauv lwm lo lus, lub teeb monochromatic).
Yuav ua li cas yog 2 hom kev yees duab?
Qhov sib txawv photometry thiab meej photometryyog ob hom kev yees duab. Lub radiant flux, luminous flux, luminous siv thiab efficiency, thiab illuminance yog cov ntsiab lus siv nyob rau hauv photometric.
Photometer siv los ntsuas dab tsi?
Photometers, uas ntsuas kho qhov muag ci ntsa iab hauv ib qhov chaw pom, yog cov cuab yeej kho qhov muag yooj yim tshaj plaws rau ntsuas lub airglow. Cov ntawv thov photometer feem ntau suav nrog cov lim nqa nqaim, kom cais tawm ib qho kev tso tawm spectral.
Lub hauv paus ntsiab lus ntawm kev cuam tshuam photometry yog dab tsi?
In reflectance photometry, diffused light illuminates a reaction mix in a carrier, and the reflected light is measured. Xwb, tus cab kuj yog illuminated, thiab cov tshuaj tiv thaiv sib tov generates ib diffuse reflected lub teeb uas ntsuas.
Koj txhais li cas los ntawm kev yees duab?
: ib ceg ntawm kev tshawb fawb uas cuam tshuam nrog kev ntsuas qhov siv ntawm lub teebkuj: kev xyaum siv lub photometer.
