Color Sphere Spectrophotometer & Colorimeter

The color sphere spectrophotometer is a highly reliable device with 45° / 0° geometry and circular illumination. It measures with the same accuracy both rough, direction-dependent surfaces, granules or powders (such as plastic concentrates and resins), as well as smooth, uniform surfaces (such as varnish layers). A white standard or zero standard (black) serves as a reference.


Special Features of the Device:

  • Fast measurement without heating the samples
  • Interchangeable screens for samples of different sizes
  • Simultaneous determination of gloss and color
     

Application Examples:


Device Configuration:       

  • LIGHT SOURCE
    • Tungsten halogen lamp with a correlated color temperature of 2854 K
    • Add-on: Minimization of infrared heating by means of an infrared absorption filter
  • IRRADIATION
    • 45° all round
