The multi-angle Spectrophotometer CM-M6 features a patented double-path illumination system that combines 45° illumination with 6 viewing angles (-15°/15°/25°/45°/75°/110° aspecular). This portable multi-angle color measurement instrument is designed for meticulous color measurement of effect paints, such as metallic and pearlescent finishes, commonly found in automotive, electronic enclosures, and more.

Spectrophotometer CM-M6

The Konica Minolta Multi-Angle Spectrophotometer CM-M6 is an innovative color measurement instrument that is designed to provide quick and precise color measurement of complex metallic and pearlescent paints. It is an ideal tool for professionals in industries like automotive, consumer electronics, etc., who need to ensure that the colors of their products meet high standards of quality and consistency.

One of the standout features of the Multi-Angle Spectrophotometer CM-M6 is its patented double-path illumination system. This system incorporates a 45° illumination and six viewing angles (-15°/15°/25°/45°/75°/110°) from two sides, which enables the color measurement instrument to deliver accurate and stable color measurements on curved surfaces (R=300 radius). This feature is especially important when measuring the color of automotive parts, such as side mirrors, which have complex shapes. In addition to its double-path illumination system, the Multi-Angle Spectrophotometer CM-M6 also boasts a small measuring area of Ø6mm, which makes it capable of measuring the color of small surfaces or parts such as automotive shark fin antennas and door handles.

The Multi-Angle Spectrophotometer CM-M6 provides data in various color spaces and indexes, including color difference, FF value (Flop value), and more. The color measurement instrument comes equipped with a high-resolution back-illuminated color display that is legible even under low ambient lighting conditions. Its ergonomic design facilitates easy handling and positioning, making it suitable for repeated use over long periods of time on the production line.
