CM-3700A Benchtop Spectrophotometer
Konica Minolta



  • Konica Minolta's advanced optical, sensing, and signal processing technology provide excellent repeatability.
  • Illumination/viewing geometry conforms to CIE, ISO, ASTM, DIN, and JIS requirements for di:8°, de:8° (diffuse  illumination/8° viewing) geometry for reflectance and to CIE, ASTM, DIN, and JIS requirements for transmittance.
  • Strictly selected high quality parts ensure long-term stability and reliability.
  • Strict accuracy control traceable to national standards ensures high quality with high inter-instrument agreement.
  • Selectable measurement areas: Measurement areas of Ø25.4mm, Ø8mm, and 3×5mm (rectangular) can be selected according to the application.
  • Switchable between SCI and SCE measurements
  • Side less transmittance chamber for unlimited sample length (Maximum thickness: Approx. 50 mm)
  • Long sample holder arm enables sample measurement at center of A4-size 
  • Sample holder arm stays open when opened fully for easy positioning of thick samples.
  • USB communication  interface for easy connection and high speed communication
  • Frame around power switch prevents switching power off by mistake.
