Fully automatic display analysis with extensive accessories

Based on a fully motorized 6-axis goniometer, the DMS 803 is used for convenient determination of the luminance, contrast and color properties of small to medium-sized displays at different viewing angles with variable electrical control.

Its scope of use embraces multiple applications in research & development and quality control. A wide range of lighting accessories and temperature control chambers make the DMS 803 particularly suitable for the characterization of displays for mobile applications (smartphone, tablet PC).
