Spectrophotometer CM-M6

The Konica Minolta Multi-Angle Spectrophotometer CM-M6 is specifically designed to provide fast and precise color evaluation of measurement of metallic and pearlescent paints on automotive exteriors. Utilizing its patented double-path illumination system with 45° illumination and 6 aspecular viewing angles (-15°/15°/25°/45°/75°/110°) as described in ASTM E2194 or DIN 5033-7 from two sides, it provides stable and accurate results even on curved surfaces (R=300 radius).

The CM-M6 comes with high resolution back-illuminated color display that is easy to read under low ambient lighting condition. With a new ergonomic designed for easy handling and positioning, the CM-M6 is ideal for repeated use over long periods of time on the production line.
