Centering the 12 V 100 W Halogen Lamp
• In the adjustment window, you see the direct
filament image and the mirror image, which in
most cases are not aligned.
• Focus the direct filament image with the col-
lector (53.6).
• Use the adjusting buttons on the rear side of
the lamp housing (53.2, 53.4) to pivot the lamp
filament’s mirror image to the side or com-
pletely out of the beam path. The lamp fila-
ment’s focused image remains visible (Fig.
54).
• Adjust the direct filament image using the ad-
justing knobs (53.1) and (46.5) so that the
centering surface is halfway covered (Fig. 55).
• Then pivot the lamp filament’s mirror image
with the adjusting knobs (53.2 and 4), and
focus it using the reflector (53.3).
• Align the mirror image symmetrically to the fil-
ament image (Fig. 56). To do so, use the ad-
justing knobs (53.2) and (53.4) again.
• Defocus the image with the collector head
(53.6) until the filament image and mirror im-
age are no longer recognizable and the image
is homogeneously illuminated.
• Exchange the reflector cube for lamp
adjustment for the original filter cube.
Note:
Turn off the microscope before exchanging
the reflector cube.
