Display Measurement Systems Model DMS 903

Tailor-made for large displays

Instrument Systems display measurement systems Model DMS 903 is ideal for photometric and colorimetric analysis of large displays. The measurement system is based on a 6-axis goniometer for determining angle-dependent characteristics and is used in quality control, as well as research and development. It permits analysis of test specimens up to a diagonal of 1500 mm (approx. 60’’), and measurement-area of 750 mm (approx. 30’’).


  • Characterization of emissive, transmissive, reflective, and transflective displays
  • 6 motorized axes for viewing-angle scan and surface scanning of samples, without rotation of the test specimen during the measurements
  • Optional array spectrometer for precise radiometric and photometric measurements
  • Analysis of all photometric and colorimetric characteristics as a function of viewing angle, electrical driving, time and temperature (optionally with forced-air temperature-control chamber)
  • Optional specular illumination for evaluation of the reflectance characteristics (e.g. BRDF) and diffuse light source with adjustable diameter (1° to 15°) for simulation of ambient illumination
