(3) Polarisation contrast in transmitted light
•
Insert the polariser (2-7/7) in the rotary stage
(2-7/9) from below so that the dot marking on
the polariser agrees with the line marking on the
stage mount and secure it with two 2.0 mm
hexagon socket screws (2-7/4).
•
Take the glass plate
∅
84 out of the option for
transmitted light illumination (2-7/5). Insert the
rotary stage in the mount (2-7/6) so that the dot
markings of the polariser agree in the x direc-
tion.
•
Fix the rotary stage with the eccentric clamp
(2-7/3).
•
Fit the glass plate
∅
72 (2-7/10).
•
Secure the specimen guide (2-7/11) with the
2.5 mm hexagon socket screw (2-7/12) or insert
stage springs (2-7/2).
•
Secure the analyser slide (2-7/14) on the dust
glass (2-7/1) or on the attachment system.
•
Slide in the slide (2-7/13) completely and adjust
the graspball to y-direction.
•
Slide in the -plate slide (2-7/8) with free
passage in the beam path.
•
In this position, the analyser and polariser are
aligned to each other at 90
°
(dark setting).
•
Fine orientation of the dark setting is possible
by undoing the eccentric clamp (2-7/3) and by
turning the rotary stage slightly.
•
The polarisation-optical ”Red I” function setting
can be selected by sliding in the
plate slide
(2-7/8).
