Oblique illumination*
To obtain a relief-like contrast; push DF slide
(CL/PH and CLP/PH condenser; 7.7) in part way
or rotate condenser disc (18.15) slightly out of
the DF position (open aperture diaphragm).

Assembly of polarizers*
Push the
analyser
(32.6) into the microscope
stand (33.1). The engraving
λ
must be on the
underneath. When incident light illumination is
switched on, the analyser must be pushed into
the slot of the illuminator (on the left side). The
rotatable analyser* (not illustrated) is turned to
the zero position.
There is also an optional intermediate tube Pol*
(Pol module A/BL) with switchable analyser and
Bertrand lens (not illustrated).
