What Does a Colorimeter Do?

Colorimeters are used to detect colour and determine the solutions concentration, i.e. when a wavelength is passed through a sample, some of the light is absorbed and some passes through. It is the wavelengths of light that pass through that are detected.

How does a colorimeter work?

In a colorimeter, a beam of light with a specific wavelength is passed through a solution via a series of lenses, which navigate the colored light to the measuring device. This analyzes the color compared to an existing standard. A microprocessor then calculates the absorbance or percent transmittance.

What two things does a colorimeter measure?

Colorimetry, measurement of the wavelength and the intensity of electromagnetic radiation in the visible region of the spectrum.
