Push out the cover cap from the inside and clip
the holder with the ground glass screen (22.5)
for lamp centration in its opening in the stand.
Insert the HC RF 4 IL module (22.2) into the stand
from above, with the turret pointing to the front
and downwards, as follows: Holding the HC RF 4
module in the longitudinal axis, tilt it slightly
forwards. Carefully put the module into the
stand with the turret as high up in the front hole
as possible.
Put four 4 mm Allen screws into the bore holes
in the HC RF 4 module, move the module to the
right and to the front so that it pushes against
the stops (22.7) and tighten the screws with the
screwdriver.
!
Attention:
Put the cover back on the microscope (caution:
built-in optics!), align by moving to the front and
to the right (22.7) and secure with the Allen
screws.
Fix the metal cover (22.10) to the side of the
stand with the 4 Allen screws (2 mm screw-
driver).
Close the mount for the IL filter magazine
with cover (22.8) and screw down the cover
with 2 cross-head screws or attach the filter
magazine (Fig. 10).
Hold the front cover (22.12, with slit) against the
microscope and push slightly so that it clicks in
position.

Diaphragm modules
The diaphragm module HC F has a centrable
aperture (23c.6 and 8) and field diaphragm
(23c.3 and 4), an engageable BG 38 red
attenuation filter (23c.11) and a switch for
blocking the incident light path (23c.12). Main
application: fluorescence microscopy.
The diaphragm module HC RF has an additional
decentrable aperture diaphragm for oblique
illumination (23b.6 and 7); instead of the BG 38
filter and the light path blocking switch it has a
light-blocking neutral density filter (23b.5),
interchangeable diffusing screens (23b.9) and
an optional focusing graticule* (23b.10).
Main applications: all incident light techniques
especially bright field and darkfield, polarized
light and ICR reflected light interference
contrast.
There is also a special MPV diaphragm module
HC for microscope photometry, and the reflection
contrast module HC RC (see separate manuals).
Assembly of diaphragm module HC F*
Push into the slot (63.5) from the left as far as
possible.
