Maximum automation for quality control and lab

The DMS 903 is ideal for the photometric and colorimetric analysis of large-format displays. The measuring system is based on a 6-axis goniometer for determining the viewing angle-dependent properties of large displays.

It is used in quality control, as well as in research and development and permits the analysis of samples up to a diagonal of 1800 mm (approx. 72”) and a measurement surface diagonal of 1270 mm (approx. 50”).

Product details:

  • Characterization of emissive, transmissive, reflective and transflective displays
  • 6 motorized axes for viewing angle scan and surface scanning of samples, without rotation of the sample during measurement
  • Optional array spectrometer for precise radiometric and photometric measurements
  • Analysis of all photometric and colorimetric properties as a function of viewing angle, electrical control, time and temperature (optionally with 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 the simulation of ambient lighting conditions
  • Motorized microscope aperture and integral alignment camera
  • Extensive accessories for testing in varying lighting conditions and temperatures

DMS accessories

  • Combined light meters: microscope, photometer, spectrometer
  • Temperature control chamber
  • Light sources and illumination units
  • Unit for sample control

DMS software

  • Software packages DMSControl (controller) and ViPer (preparation and evaluation of readings)
