Spectrophotometer, tseem hu ua spectrometer (spectrometer), yog lub teeb ci ntawm cov muaj pes tsawg leeg ua ke, yog decomposed rau hauv kab ntawm cov khoom siv hluav taws xob. Kev ntsuas ntau yam feem ntau muaj xws li wavelength ntau ntawm 380 ~ 780 nm pom lub teeb pom kev thiab thaj tsam ntawm thaj tsam 200 ~ 380 nm uv teeb pom kev. Qhov sib txawv lub teeb muaj nws cov xeeb ceem ntawm cov duab hluav taws xob, yog li tuaj yeem txais yuav lub teeb sib txawv raws li lub teeb ci ntawm qhov ntsuas. Tungsten lub teeb tawm emission: tungsten lub teeb ci los ntawm lub teeb pom kev ntawm 380 ~ 780 nm wavelength lub teeb los ntawm prism refraction, tuaj yeem tau txais los ntawm liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab ntshav ntawm cov chromatography txuas ntxiv; Cov chromatography tuaj yeem ua lub teeb ci hauv qhov pom lub teeb pom kev zoo spectrophotometer.
