A wide range of accessories was developed to make maximum use of the test and measurement options offered by the DMS instruments. This means that the comprehensive electro-optical characterization of displays can be carried out using just one measurement system.
Spectrometer option
Alongside photometric data, all colorimetric and radiometric parameters of displays can be captured using the proven spectrometer CAS 140CT.
Forced-air temperature-control chambers
Chambers with air-flow temperature control permit measurement of the test specimen at stabilized temperatures in the range from -40° to +85°C.

Light sources and illumination units
A range of different illumination units is supplied to simulate the effect of ambient light (diffuse, specular, point-light source, etc.). A HEL-4 halogen light source is attached to each illumination unit as standard.

Software
All measuring instruments in the DMS Series are supplied as standard with the two software packages DMSControl for operating the instrument and ViPer for visual performance evaluation of the test results. A Report Generator Module is supplied as an option for exporting data into Excel. A DCS Device Control System is also supplied for controlling external devices (video generators, power sources, source meters, etc.).
