Class leading color matching sensor for LED illumination inspection. Identify RGB composition values and brightness with high resolution. Differentiate the variation of white LEDs in brightness and color composition.

  • Identifies the color proportion and brightness of LEDs by analysing light into three primary colors; red, green and blue
  • Equipped with two seperate outputs for RGB composition values and brightness
  • Resolving power: 0.01% color proportion and 0.1% brightness
