For operation at a flash frequency of 100 Hz (mean value), the average illuminance ob-
tained is as indicated in Table 3.1.

These values are reduced if optical cables other than the B&K standard cable are used. For exposure
calculations consider reductions from additional optical systems

ble AE 6100 at the flash frequency of 100 Hz (mean value)
For use with other types of optic cable a Blank Coupler DP 0594 is supplied. The dimen-
sions of this Coupler are shown in Fig. 3.7., and when drilled with an appropriate sized
centre hole it can accommodate cables up to 17,5 mm in diameter. For optimal light
output it is important that the input face of the optic cable protrudes just under 40 mm
from the flange of the Coupler. See Fig. 3.7.
&
The end of the light cable must not protrude more than 40 mm from the flange of the
Coupler. The diameter of the optic cable at its far end must not exceed 8 mm.
