Electrical connection of the XBO 450W Xenon
lamp and the HBO 200W/2 mercury-vapor
high-pressure lamp
The electrical connections of the lamp are described
on page D13 and D14.
PLEASE NOTE!
Before lighting the lamp, close the lamp house
and select heat and UV blocking filters in the
mirror house.
⚫ To protect the sensitive electronics of the auto
photo mode, these are turned off during the ignition
of the lamp.
⚫ When the lamp is switched on, the connecting
device is switched on first, placing the fan in the
lamp house 50 into operation. Then the lamp is lit
with the red start button
➁
. If the fan should fail
during operation, the lamp is switched off
immediately.
Adjust the XBO 200 W/2 450W Xenon lamp and
the HBO 200W/2 mercury-vapor high-pressure
lamp:
⚫ Turn to the 10x objective, and insert the 10x
eyepieces into the observation tube.
⚫ Ignite the lamp and with no specimen on the
stage, set the Univar to transmitted-light brightfield
with the high-performance lamp for the light source
⚫ Swivel ground-glass off.
⚫ Turn off automatic zoom lighting and adjust the
zoom handwheel to 63. Turn the collector knob of
high-performance lamp clockwise until it stops.
⚫ Redirect the microscopic optical path to view the
lamp arc on the projection screen. This is done
through height adjustment of the brightfield
condenser NA=0.90 or NA=1.30 with the condenser
knobs, or with coarse and fine adjustment of the
microscope. If there is no projection head, the
observation of the arc is made through the
eyepieces using the ocular body’s neutral density
filters.
⚫ There will be seen two arc images, fig.a: one
directly from the collector, the second from the
reflector built inside the lamp house.
⚫ The side adjustment screw
➉
on the lamp house
is used to set both images to the same size. Then
you can superimpose both images as in Fig.b, by
turning the two screws
➈
located on the front of the
lamp house. This way the arc will be located exactly
on the collector/reflector optical axis
