A colour measuring device for measuring/comparing colours.
It is often used to calibrate monitors or in biology/chemistry for analyses. More sophisticated devices, such as the spectrophotometer, can measure colours spectrally and are also used for proofing to verify or calibrate printers.
The aim of colour management is to ensure that colours are reproduced as similarly as possible across different devices such as cameras, scanners, monitors, laser, inkjet, offset printers and many more.
Colour measurement is used to determine the exact colour location of a colour in a colour system.
In order to describe colors accurately and avoid metamerism, modern color measurement is increasingly no longer carried out via colorimeter that can measure one color spot in the 3-dimensional colorspace LAB, but by spectral measurement, ie the recording of the complete emission spectrum or reflection spectrum of a color.
Spectral photometers (or spectrophotometers) are high-quality colorimeters that can measure and accurately describe any colour.
