CMF Color Analyser PW0049

The module PW0049 is a stand-alone measuring device 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

  • Output of color values in X,Y,Z (Tristimulus) and x,y,Y (Chromaticity) according to CIE1931 2°
  • Output of color values in Lab according to CIELab - Reference illuminant to be selected
  • Output of color values in RGB
  • ΔE output against a definable reference
  • all results via PC-Interface and 3 analog channels 0-10V
  • Digital input Start Measurement and output Measurement Ready
  • 13 Bit resolution, Dynamic >120 db
  • Wavelength 400 - 700nm with synchronous sampling of all color channels
  • Temperature compensation in range 20-55 degree Celsius
  • Cycle time approx. 25ms per measurement
  • Indication of dominant wavelength in nanometers and color temperature in Kelvin in connection with PC tool
  • Interface USB 2.0
  • Power supply 24V DC, 500mA

Available variants:

PW0049 Interface USB 2.0 and analog outputs

Application range:

  • Optical measurement of color and intensity according to CIE 1931, e.g. LED´s, Lamps, Displays etc.

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.
