An absorption spectrophotometer is a device used to measure absorbed light intensity as a function of wavelength. In UV–visible spectrophotometers, a beam of light from a suitable UV and/or visible light source is passed through a prism or diffraction grating monochromator.The light then passes through the sample to be analyzed before reaching the detector (Fig. 4.2).
