The Konica Minolta Spectrophotometer CM-26d (dual aperture model) and Spectrophotometer CM-25d (single aperture model) are essential color measurement instruments for digital color data management within global supply chains. These advanced spectrophotometers offer accurate and consistent color measurements, ideal for various applications like automotive interiors, the exterior of smartphones and tablets, ceramics, and more.

Spectrophotometer CM-26d / CM-25d

The Konica Minolta Spectrophotometer CM-26d and Spectrophotometer CM-25d, with d:8° geometry and horizontal alignment, are designed for color measurement of various samples such as automotive interior parts and trims, small plastic parts, electronic devices, ceramics, and more. These spectrophotometers provide high accuracy and repeatability for consistent digital color data management within a supply chain.

With tight inter-instrument agreement levels of ∆E*ab< 0.12 (CM-26d) and high repeatability of σ∆E*ab 0.02 (CM-26d), the CM-26d and CM-25d ensure precise color measurement results. In addition, the CM-26d and CM-25d are designed with user-friendly features for easy and efficient operation. The viewfinder allows for precise positioning on small or difficult-to-measure samples, while the symmetrical and compact design makes it suitable for measuring in tight spaces, e.g., vehicle interior.

The Configuration Tool CM-CT1 software (standard accessory) further enhances the capabilities of these spectrophotometers by allowing users to create and share instrument settings among instruments. When used together with Spectramagic NX or Spectramagic NX2 software, the CM-26d and CM-25d enable users to create workflow instructions with images, streamlining the communication and standardization of color measurement processes.
