Halogen lamps: LH 106
Adjust the collector (37.4) until you see the lamp
filament (Fig. 38). If using the fluorescence
illuminator, you will only be able to see a few
coils of the filament.
Using a hexagonal screwdriver (2.2) adjust the
horizontal position (37.3) of the lamp holder until
the slightly brighter stripe in the reflection of the
lamp filament is in the centre of the brighter
area (Fig. 38), as marked by the dot you made.
Then move the reflection of the lamp filament
with the vertical adjustment (37.2) to the centre
of the range of movement.
No adjustment is needed for lamphousing 105/2
(not illustrated). It is very important that the lamp
sits straight in the holder.
Halogen, Xe and Hg lamps: LH 106 z
Lamphousing 106 z: Halogen, Xe, Hg lamp (Fig.
40 and 41).
The image of the light source is focused with
the collector (40.6), if using the fluorescence
illuminator you will only be able to see a few
coils of the lamp filament.
The adjustment principle is similar for all light
sources:
Move the
reflection
of the lamp filament or
discharge arc to side (41a) by turning the
adjustment screws on the back of the
lamphousing (40.2 and 40.4).
Focus the
direct image
of the filament or
discharge arc (40.6) and adjust as follows (41b,
40.1/40.5 and 40.6):
Halogen lamps:
just above or below the center
marking you made (Fig. 41b), or, especially
for higher objective magnifications, as for the
Xe lamp (Fig. 41c), i.e. in the centre =
superimposing.
