), remove the halogen illuminator
3
) which is ready for use from the
microscope stand.
•
Switch on the microscope.
•
Direct the light beam to a projection surface
(wall) at a distance of at least 3 m.
Do not look into the light exit aperture
of the illuminator.
•
Using a 3 mm ball-headed screwdriver, turn the
adjusting screw (Fig. 51/
3
) until both images of
the lamp filament appear as sharp as possible
on the projection surface.
•
Then turn the two adjusting screws (Fig. 51/
4
and
5
) until the lamp filament of one image
exactly fills the gaps in the reflected filament
image (Fig. 51/
1
).

If necessary, loosen the clamping screw
(Fig. 52/

) and remove the HAL 100 from the
transmitted light illumination mount.

from the mount (anti-clockwise). Hold the edge
of the diffuser by the projections on the disk
(Fig. 52/

•
Reattach the HAL 100 and tighten the locking
screw.
•
Remove filters (if inserted) from the optical path
or deactivate them.
•
Focus on the specimen using a
≤
40x objective
and find a free area on the specimen.
•
Remove the eyepiece and center the lamp
filament and its reflection in the pupil image
using the adjusting screws (Fig. 51/
4
and
5
).
•
Turn the adjusting screws (Fig. 51/

illumination of the visible image is as
homogeneous as possible.

Once you have completed the adjustment,
remove the HAL 100.
