General Information
The
CD-LUX
Luminance/Illuminance Meter has been designed
for use in conducting the acceptance and constancy tests
according to DIN 6868/157 "Acceptance and constancy
testing for image display devices,” the constancy tests as well
as the corresponding testing of viewing boxes per DIN
6856/1+2.
The
CD-LUX
fulfills the requirements for luminance meters
according to DIN 5032/7 Class B.
Luminance meters which are placed in direct contact with the
monitor surface are not suitable for the evaluation of existing
viewing conditions as they do not measure the contrast
reducing, reflected ambient light.
Thanks to its spacer leg, the
CD-LUX
is able to include
reflected ambient light in its measurements.
The built-in laser positioning aid of the
CD-LUX
enables its
precise alignment over the desired measurement point on the
monitor surface as the laser beam is so aligned that it
intersects the optical axis of the optical measurement system
at the monitor surface. In addition, the laser, together with the
laser control window, helps to ensure a perpendicular
alignment of the optical measurement system vis-à-vis the
monitor surface.
