Colour Analysis

UltraScan VIS

The UltraScan VIS color measurement benchtop spectrophotometer measures opaque, transparent, and translucent solids and liquids in the complete CIE recommended spectral range of 360 – 780 nm. It can be used in production and in the laboratory for inspecting raw materials, evaluating finished product or developing methods for color analysis.

  • Measures reflectance, transmittance and haze
  • Wavelength range 360 nm - 780 nm
  • 10 nm optical resolution and reporting interval
  • Two reflectance measurement areas
  • Exceptional inter-instrument agreement
  • Automated UV calibration and control
  • Large transmission compartment open on three sides
  • Includes EasyMatch QC software
