Place the specimen on the stage, focus on it
and rotate the control wheel (4-129
) on the
C-DIC slider

1
) until the specimen detail of interest is
visible at maximum contrast. Rotating the stage
is no longer necessary. If both line marks are
facing each other (4-130/
3
), this corresponds to
the mid-position. Rotation by 45° in both
directions is possible).
•
The contrast can be optimized by turning
setscrew (4-129/
2
) on the C-DIC slider or on the
modulator turret (4-130/
2
). If triangular and line
mark are facing each other (4-130/
3
), this
corresponds approximately to the extinction
position (best contrast).
