Article No. 7049
BYK-mac i Pro
Multi-angle spectrophotometer with Sparkle index ANO
- Measuring area: 23 mm diameter
- 6-angle color measurement
- Graininess measurement with CCD camera
- Modified image analyzing algorithm to measure Sparkle index ANO
- Professional data documentation and analysis with Flake Analyzer and smart-chart software
Features
The surface finish of anodized products is influenced by its sandblasting and anodizing process. BYK-mac i Pro objectively evaluates process variations with multi-angle color, graininess and sparkle measurement.
- Total color impression of anodized surfaces:
- Multi-angle color to determine lightness and color flop: -15° / 15° / 25° / 45° / 75° / 110°
- Graininess to characterize very fine textures
- Sparkle index ANO to describe sparkling behavior
- 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

Multi-angle Color Measurement
Today effect finishes play a dominant role in many applications as they make an object distinctively appealing. In contrast to conventional solid colors, effect finishes change their appearance with viewing angle and lighting conditions. Interference finishes show not only a lightness change with different viewing angle, but also a change in chroma and hue. The latest developments are special effect pigments, which create sparkling effects when lighting conditions change from sunlight to cloudy sky.In order to describe these effects objectively instrumental measurement is performed with multi-angle spectrophotometers. The following article reviews visual evaluation of effect coatings, measurement principle of a multi-angle and effect spectrophotometer and illustrates data interpretation of sparkle and graininess values.
