The effect of ambient light on display properties is gaining in importance. In addition to various light sources, five different illuminating devices can be connected to the DMS systems, reflecting all relevant ambient conditions for a display:
DHS diffusing hemisphere
SDR integrating sphere for diffuse reflectance
VADIS variable aperture diffuse source
PID parallel illumination device
PLS point light source
They simulate various different lighting conditions for the measurement of emissive, transmissive, reflective and transflective display properties
