Motorized goniometer DMS 903

6-axisfor large displays

The 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’’). Features • 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 Specifications DMS 903 : Goniometer / Positioning : 6 motorized axes (inclination, azimuth and height adjustment of the measuring head, x-y positioning, inclination of the reflective illumination device) Maximum sample size (L x W) : 1300 x 1600 mm (72″ diagonal for a 16:9 panel) for center measurement; 650 x 1100 mm (50″ diagonal for a 16:9 panel) for full x-y scanning range Maximum traverse : 600 x 450 mm Maximum sample thickness : 280 mm Alignment of the sample : Horizontal (no rotation of the sample during measurement) Detectors : Photometer PMT 3 (standard); Spectrometer (optional)
