Illuminated Symbol Testing
A ProMetric system (comprised of an imaging colorimeter and ProMetric Software) is a simple and accurate solution for testing illuminated characters. The software features a powerful tool (Auto-POI, or Automatic Points-of-Interest) that allows users to automatically select points of interest based on location or color and luminance values (Lv and CIE x,y thresholds). You can then run calculations on a single character, or a group of like-characters, to ensure uniformity within or between symbols regardless of location, shape, size, or color. The Auto-POI system provides comprehensive data through ProMetric Software, including average luminance across characters, points of minimum and maximum luminance, color value, and dominant wavelength.
