Minolta CM-M6 Multi-Angle Spectrophotometer for color measurement of pearlescent coatings metallic or effect paints
The model CM-M6 is a portable multi-angle spectrophotometer especially designed for color measurement of metallic or effect paints, such as pearlescent coatings, which can exhibit a noticeable visual change with specific angles of view. 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. Its compact and lightweight vertical shape is easy to hold by one or two hands and enables easy positioning, while the high-resolution back-illuminated colour display is easy to read even in the lowest ambient lighting conditions.
Features
- Double-path illumination/observation system for stable measurements on curved surfaces
- Compact and lightweight vertical design allows fast and accurate QC in production line
- Large high-resolution, back-illuminated color display
- Optional Bluetooth®
