The instrument used to measure the amount of light of a specific wavelength absorbed or transmitted by a substance is called a spectrophotometer. In a spectrophotometer, a sample of the substance is placed across the path of a light beam of a chosen specific wavelength. The spectrophotometer determines the intensity of the light entering the sample and the intensity of the light leaving the sample, then calculates the amount of light transmitted and absorbed by the substance.
