The CM-M6 is a portable multi-angle spectrophotometer especially designed for colour measurement of metallic and effect paints and plastics. It uses a new, patented double-path illumination system with directed 45° illumination and 6-angle observation (-15°/15°/25°/45°/75°/110° aspecular) from two sides to accurately measure painted parts at the automotive production floor.

This new, patented optical measurement system is optimized to give accurate and stable results even on curved surfaces. Therefore, samples such as front and rear bumpers, vehicle mirror bodies or door handles can be measured fast, accurately and repeatedly.
