• 5-angle color measurement for light/dark travel evaluation: 15° / 25° / 45° / 75° / 110°
• Additional color measurement behind the gloss for color flop analysis: -15°
• Detection and quantification of fluorescent light excited in the visible range (Intensity Emission)
• Excellent agreement between instruments allows use of digital standards among the supply chain
• Stable, long-term calibration – needed only every three months
• Temperature independent results (10 – 40° C) – without calibration
• Stable positioning due to 4 trigger pins on bottom plate – operator influence minimized
• 10 year warranty on LED light source – no lamp changes needed

Fluorescence is the spontaneous emission of light by a substance that has absorbed light. Part of the emitted light is released as heat. Therefore, the fluorescent light is typically of lower energy and thus, longer wavelength than the exciting light.

This phenomenon is called “Stokes Shift” and well known for optical brighteners that absorb light in the UV-range and emit the fluorescent light in the blue wavelength range.

But, it can also occur in the visible range e.g. light excited in the blue wavelength range can be shifted to the green, yellow or red wavelength range.

The instrument is operated with a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack in the instrument as well as a spare pack located in the docking station. Optionally the instrument can be operated with 4 standard mignon alkaline or rechargeable batteries. The docking station also transfers the measured data to a PC. For professional analysis, documentation and data management smart-chart software is included.
