To determine the brightness on an acrylic surface (measured in cd/sqm), our field staff always carry the most modern measuring equipment "on their person".
In our in-house laboratory, high-tech equipment is also available to carry out special measurements:
For example, instruments from Zeiss, Minolta or Gossen are used to determine colour nuances. An integrating sphere with a diameter of 50 cm is used to measure the light output of an LED in lumens.
