Konica Minolta CM-M6 Multi-Angle Spectrophotometer

Konica Minolta CM-M6 Multi-Angle Spectrophotometer

The Konica Minolta CM-M6 is a multi-angle spectrophotometer featuring a breakthrough design that delivers rapid and precise color analysis for inspecting metallic paints and pearlescent effect pigments on automotive exterior parts. Incorporating proprietary patented double-path illumination technology—illuminating at a 45° angle paired with six aspecular viewing angles (-15°/15°/25°/45°/75°/110°) complying with ASTM E2194 and DIN 5033-7 specifications from both sides—the instrument guarantees highly reliable and accurate measurement results even on curved surfaces with a 300mm radius.

The Konica Minolta CM-M6 is equipped with a high-resolution backlit color LCD display, ensuring excellent readability even under low-light conditions. Designed with an ergonomic vertical form factor, it is easy to hold and position, making the CM-M6 an ideal tool for continuous, long-term deployment on busy production lines.
