The difference between three-stimulation instrument and spectrophotometric color measuring instrument

Definition of Three-Stimulation Instrument and Spectrophotometry Instrument

The advantages of tristimulus instruments are their small size and easy portability. They are used to measure color differences in production and inspection departments.

Spectrophotometric Colorimeters with low air pressure and the ability to measure absolute color, they are mainly used in scientific research departments

The difference between three-stimulation instrument and spectrophotometric color measuring instrument

The tristimulus values color difference meter has the characteristics of relatively low price, small size, outstanding flexibility and easy operation. It can easily measure tristimulus values. However, the color difference meter is not suitable for complex color analysis such as reflectance Light spectrum and color intensity.

Spectrophotometers have high accuracy and increasing versatility. Because it can measure reflectance Linear dispersion at each wavelength, it is more suitable for complex color analysis. Of course, Spectrophotometer s are also more expensive than color difference meters. Before choosing different types of instruments, you must consider how high the requirements for color accuracy are in the application field.
