Maximum flexibility for quality control and lab analysis

The DMS 904 was developed for photometric and colorimetric analysis of very long, curved displays. The measuring system is based on a 7-axis goniometer. Its additional X-axis ensures maximum freedom of movement, enabling the measurement of all display types for modern automotive cockpits and determination of their viewing angle-dependent properties.

The DMS 904 is used in both quality control and research & development. Its spacious interior is designed for specimens up to a size of 1800 mm x 1200 mm (about 85”).

Product details:

  • Characterization of emissive, transmissive, reflective and transflective displays
  • 7 motorized axes for visual direction scan and flat scanning of samples, without rotation of the specimen during measurement
  • Examination of all photometric and colorimetric properties as a function of viewing direction, electrical control, time and temperature
  • Optional temperature control chamber for measurements on long, curved displays (XZ scan)
  • Optional array spectrometer for precise radiometric and photometric measurements
  • Optional directional lighting for the evaluation of reflective properties (e.g. BRDF). Diffuse light source with adjustable diameter (1°–15°) for the simulation of ambient lighting
  • Motorized microscope aperture and integrated viewfinder camera
  • Extensive range of accessories for testing under varying lighting and temperature conditions

DMS accessories

  • Combined light meters: microscope, photometer, spectrometer
  • Temperature control chamber HCS-7 (-40 °C to +105 °C) for lateral moving measuring heads
  • Light sources and illumination units
  • Unit for sample control

DMS software

  • Software packages DMSControl (control) and ViPer (preparation and evaluation of measurement results)
