Up to 4 positions can be occupied by rotating
the turret.
In combination with incident light darkfield, a
neutral filter (Fig. 21) can be slotted onto the
BF reflector (for brightfield, polarized light and
interference contrast) to avoid glare when
switching between illumination techniques.
The adjusting reflector, Smith reflector and DF
reflector can only be placed at
opposite
positions. The 4 turret positions are each
marked on the left of the dovetail guide with the
numbers 1 – 4 (20.3). In addition the position
currently in the light path is indicated on the
outside of the turret (20.1). Self-adhesive labels
indicating the positions 1 2 3 4 and the
abbreviations for the filter blocks and the
reflectors (e.g. D) are enclosed with the filter
systems and reflectors. Stick the label 1 2 3 4
.
in its place in the upper line on the front
plate (Fig. 19).
Then stick the labels with the abbreviations in
the corresponding fields underneath according
to the marking on the systems (20.2) and the
number indicated on the left on the filter wheel
(20.3). The Smith reflector (with two reflecting
surfaces and lenses, Fig. 18.4) and the DF
reflector (with ring mirror, Fig. 18.3) do not have
a label.
Push the front cover hard until it locks back into
place.
