Optical Coatings System    :  Bespoke automated system that measures and assesses the optical characteristics and average thickness of coating samples

Optical Coatings System

The optical coatings system is a bespoke piece of equipment designed for the Centre for Process Innovation (CPI). The system is designed to measure and assess the optical characteristics and average thickness of drawn-down samples on substrates.

Samples are loaded onto a vacuum bed of calibrated flatness and presented to a range of measurement devices using high precision ball-screw axes. Fully configurable workflows allow an image analysis camera to detect areas of interest and define regions for measurement using a Zeiss Spectrophotometer, Laser Profilometer with sub-micron measurement capability and a Tri-Gloss IQ Goniophotometer.


  • User friendly software interface.
  • Compatible with a range of substrate types & sizes.
  • User configurable workflows.
  • Automated image analysis of defect free regions for measurement.
  • Optional user defined regions for measurement
  • Automated calibration of measurement devices.
  • Measurement of: Colour, Reflectance, Gloss (20°/60°/85°), RSPEC Gloss, Haze, Distinctness of Image (DOI) Reflected Image Quality (RIQ) and Full colour image capture.
  • Calculation of: Tristimulus XYZ, Scatter coefficient, ΔE2k, ΔECMC and contrast ratio.
  • Barcode reading.
  • Onscreen data representation
  • MS Excel compatible export data.
