Color measurement

Color measurements are used to assess color changes induced by various stresses.

The following characteristics of a specimen are measured or calculated in an automatic spectral photometer with the help of the CIELAB table system:

  • Transmittance
  • Reflectance
  • Yellowness index
  • L*a*b* values
  • Standard color values XYZ
  • Delta E
  • Spectral analysis
