Color Matcher PR0049

The module PW0049 is a stand-alone measuring device for the operation in production environment which is conceived for the absolute measurement of self-illuminating objects.

Its function is to reproduce the CIE 1931 2° CMF's as precisely as possible. The resulting Tristimulus measuring values X, Y, Z form the basis of most of the common color spaces used today.

By means of the integrated three-sector color sensor and additional procedures, the visional sensation of the human eye is imitated with an accuracy that can be compared to decidedly more elaborate spectrometric procedures.

The scope of delivery contains a comfortable and intuitive software tool for setup, parameterization and output of color values in different modes.

Special optimizations for the following light sources are contained in the scope of delivery:

  • CCFL
  • LED white
  • LED colored
  • Rot optimized LED´s
  • RGB Backlight
  • White LED Backlight
  • RGB light source
  • RGB and white

Software Tool

The software tool shows all actual status and color values continuously.

In addition the function „Color Controller" can be activated. With that the color and intensity can be output via the 3 analog outputs for the control of a external light source.

The module automatically controls the given values and keeps them constant.

A WIN 32 Low Level DLL is available for the integration in own written software.
