CM-26dG / CM-26d

Portable spectrophotometer with d:8° geometry and horizontal alignment

  • Portable Spectrophotometer
  • Wavelength range 360-740 nm
  • d:8° Sphere Geometry
  • Simultaneous SCI / SCE measurement
  • 2 Apertures SAV / MAV
  • UV calibration
  • CM-26dG:
  • As CM-26d with integrated 60° Gloss Sensor

The CM-26dG and CM-26d, are the successors to the widely used CM-2600d spectrophotometer.

Portable sphere type spectrophotometers with horizontal alignment, designed for maximum performance when measuring the colour of flat or large samples. These close tolerance devices perform measurement both including (specular component included - SCI) and excluding (specular component excluded - SCE) surface conditions in one measurement sequence, significantly faster than the previous generation.


  • 2 measurement apertures: choice of either medium aperture measurement (8mm) or small aperture measurement (3mm), to adapt to small or patterned samples
  • Integrated ISO compliant 60° gloss sensor (CM-26dG): gloss measurement data is captured and stored with colour data, greatly reducing the measurement and analysis time where both appearance characteristics are reported
  • Sample observation port: illuminated sample positioning window allows the operator to accurately and repeatably position the measurement aperture
  • Large colour display: simple user interface minimises the risk of operator errors and measurement data is displayed both numerically and graphically 
  • Rechargeable battery: lithium-ion battery is charged via USB bus power and additional batteries can be charged with external charger (optional)
  • Configuration Software: compatible with the CM-CT1 software that allows an administrator to quickly configure multiple instruments, lock device settings and perform remote troubleshooting and training over screensharing software
  • Close tolerance by default: maximise the accuracy and certainty of digital colour data throughout the supply chain, confident that all measurement data is traceable
