Single aperture version of Konica Minolta Sensing's top of the range portable spectrophotometer with the same simple, modern user interface and built-in sample viewer.

  • Portable Spectrophotometer
  • Wavelength range 400-700 nm
  • d:8° Sphere Geometry
  • Simultaneous SCI / SCE measurement
  • Rechargeable Lithium-ion battery

Medium aperture portable spectrophotometer

d:8° geometry instrument with 8mm measuring aperture and horizontal alignment, ideal for flat samples or measurements in narrow spaces.

The CM-25d is the direct successor to the CM-2500d, measuring colour data for specular component included (SCI) and specular component excluded (SCE) in a single measurement.

The CM-25d benefits from the same user friendly interface as the CM-26dG with improved sample viewer, large colour screen, simple ambidextrous control panel, and lithium-ion battery (removable) with the option to charge additional batteries in an external charger.


A cost effective portable for customers who do not require the unmatched accuracy and close tolerance performance of the CM-26d. The CM-25d uses the same firmware and user interface to deliver a simple, modern colour measurement experience.
  • Built-in Display: greatly improved usability and reduced risk of operator errors, measurement data is shown graphically and numerically.
  • Illuminated Sample Viewer: seamlessly align the instrument with the measurement area and preview the sample to ensure that the correct area is measured.
  • Updated design: lightweight instrument designed for ambidextrous operation via intuitive control pad.
  • Rechargeable Battery: lithium-ion battery (removable) charged via USB bus power can be backed up by additional batteries and external charger (optional).
  • Compatible with CM-CT1 configuration tool: allowing configuration of multiple devices via config file, device administrator to prevent operator settings and remote support/training via screensharing.
