4.2 Setting reflected-light illumination
• By pressing the knob ((Fig. 14/5), the reflected-
light illumination is switched ON or OFF (spot
illuminator or double spot illuminator).
• By turning the knob, the illumination intensity
of the switched-ON reflected light illumination
can be adjusted.
4.2.1 Spot illuminator
• Push spot illuminator in the guide to the
required height (Fig. 16/2).
In the lower positions, an oblique light
effect is created to produce cast
dows for enhancing surface
structures.
• Set the angle (Fig. 16/1) via the pivot of the
spot illuminator so that the object is optimally
illuminated.
• Set size and brightness of the spot by axially
shifting the focusing unit (Fig. 16/3)
(illumination zoom).
4.2.2 Double spot illuminator
• Move the microscope body to its uppermost
position via the focusing knob (Fig. 17/1).
• Push double spot illuminator (Fig. 17/2) to the
required level within the guide.
• Bend the two goose necks (Fig. 17/3) to adjust
the spots so that the specimen is optimally
illuminated.
Here again, an oblique light effect can
be produced in the lower positions with
the goose neck set horizontally.
