Ib yaam nyuag ntawm Spectrophotometer

Spectrophotometer, kuj hu ua spectrometer (spectrometer), yog lub teeb uas muaj pes tsawg leeg txoj, yog decomposed ua cov kab spectral cov kev pab li sawv daws. Xab ntau feem ntau muaj wavelength ntau yam ntawm 380 ~ 780 nm pom lub teeb thaj av thiab wavelength nyob rau hauv lub chav 200 ~ 380 nm uv lub teeb cheeb tsam. Qhov ntau hom teeb ci tau nws cov xeeb ceem ntawm cov emission spectrum, li no thiaj yuav sib txawv raws li yog lub teeb qhov ntsuas tau. Tungsten lub teeb emission spectrum: tungsten hom teeb ci los ntawm tus spectra ntawm cov 380 ~ 780 nm wavelength lub teeb ntawm plaub refraction, yuav ua li cas yog liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab ntshav kev nruam chromatography; Tus chromatography tswj tau ib lub teeb nyob hauv qhov pom lub teeb spectrophotometer.
