Light filters
Up to max. 3 light filters can be inserted in the filter holder (1.16). They can be switched in and out
the light path as required.
Filter Use
Grey filter Grey filters (neutral density filters) are used to
attenuate the light without influencing the
colour temperature. The engraved value, e. g.
N16, indicates the attentuation value. So N16
means reduction to 1/16 = 6.3 % transmission.
