CENTRAL ILLUMINANCE

Ec

illuminance at a 1000 mm distance (or a measurement distance specified by the MANUFACTURER if the specified working range does not include 1 000 mm) from the light-emitting area of the ME EQUIPMENT in the LIGHT FIELD CENTRE without any obstruction of the light beam DEPTH OF ILLUMINATION ABOVE 60%

working distance around the 1 000 mm distance (or a measurement distance specified by the MANUFACTURER if the specified working range does not include 1 000 mm) below the emitting surface of the ME EQUIPMENT, in which the illuminance reaches at least 60 % of CENTRAL ILLUMINANCE (Ec)
