Fast Photometer For Analysis Of Temporal Luminance Variations

DMS 505 Display Measurement Systems is built to characterize small to mid-sized flat panel displays with a 6 axis goniometer with 3 motorised axes.

Instrument Systems DMS 505 is ideal for determining the characteristics of displays for mobile applications (smartphones, tablet PCs) with the comprehensive range of accessories including illumination devices and temperature control chambers.

DMS 505  measurement system permits angle-dependent analysis of all electro-optical characteristics of displays, including luminance, contrast, and color properties of displays at different viewing angles and variable electrical driving.


  • Angular scan: variation of luminance, contrast and chromaticity with viewing direction for evaluation of directional uniformities and BRDF
  • EOC: variation of luminance, contrast and chromaticity with electrical driving for evaluation of EOTF-characteristics (e.g. gamma)
  • Transients: luminance versus time for e.g. response time evaluation
  • Reflectance characteristics under diffuse and directional illumination
  • Customer specific measurements defined with DCI scripting sequences
