Colorimeter

A colorimeter is a light-sensing device that is used to measure the absorbance and transmittance of light as it moves through a sample of liquid.

​The main components of a colorimeter include:

Illuminant: A specific, fixed light source that passes through the object.

Cuvette: A sample holder where the liquid is placed.

Standard observer: A two-degree standard observer, which is a small and specific field of view.

Photocell: A system that detects light passing through the sample.

Tristimulus absorption filter: A filter that isolates specific wavelengths to be applied to the sample.

​There are two different types of colorimeters:

Color densitometers: Measure the density of primary colors.

Color photometers: Measure color transmission and reflection.

Colorimeters may also be compact and portable to use on the go or larger for benchtop use in a lab.

What is a Color Spectrophotometer ? A color spectrometer is a color measurement device used to capture and evaluate color. As part of a color control program, brand owners and designers use spectrophotometers to specify and communicate color, and manufacturers use them to monitor color accuracy throughout production.
