Spectrophotometry - Latest research and news | Nature
Spectrophotometry is a method that measures the amount of light that a sample or object absorbs or reflects as a functional of wavelength using an instrument known as a spectrophotometer.
Principle of Spectrophotometer and its Applications| Chemistry| Byjus
The spectrophotometer is an instrument which measures the amount of light that a sample absorbs. The spectrophotometer works by passing a light beam through a sample to measure the light intensity of a sample. These instruments are used in the process of measuring colour and used for monitoring colour accuracy throughout production.
