What are the parts of colourimeter?

A colorimeter typically consists of several key parts: a light source that emits specific wavelengths of light, a sample holder or cuvette where the solution is placed, and a detector that measures the intensity of light transmitted through the sample. Additionally, it may include a filter to isolate the desired wavelength and a display or output system to present the results. These components work together to determine the concentration of colored substances in a solution based on light absorption.
