3.33.3 Aligning the HBO 100 illuminator
The HBO 100 illuminator is available in two
versions (manual and automatic alignment).
The self-adjusting HBO 100 (423011-9901-000) is
aligned automatically after switching on the
transformer of the illuminator.
The alignment of the manually aligned HBO 100
illuminator (423010-9901-000) is described below.
If the FL attenuator (manual or
motorized) is in the reflected-light
path, set it to 100% transmission for
illuminator alignment.
• Switch on the HBO 100 illuminator (Fig. 56/1)
via the HBO 100 transformer (Fig. 85/2) and
allow it to warm up to the operating
temperature.
• Pull adjusting aid (Fig. 55/1) out of the
microscope stand. The brighter arc spot of the
HBO 103 W/2 lamp and its slightly darker
reflected image become visible in the black-
glass window of the adjusting aid.
• Turn the knurled knob (Fig. 56/4) for collector
adjustment to focus the brighter arc spot.
• Use the adjusting screws (Fig. 56/2 and 3) to
adjust the darker arc spot (reflected arc image)
within the marked alignment circle as shown in
the arc spot illustration (Fig. 55/2).
• Replace the adjusting aid.
The two arc spots of the HBO 103 W/2
lamp in the alignment circle of the
adjusting aid should be right next to
each other!
