Centering the lamp
Center the lamp before using the fluorescence attachment for the first
time, or after you have exchanged the lamp. If the lamp is not centered
correctly, the image can be dark, or there might be an uneven illumination.
The procedure of lamp centering is the same as the procedure described in
the instruction manual for the super high pressure mercury lamp power
supply except for the following three points. 1: The centering tool is not
needed, 2: the vertical position adjustment of the zooming body is needed,
and 3: the position of the collector lens should be adjusted once again after
the lamp is centered. The ark image is seen in the same way, and the
centering screws work the same way as described in the manual of the
super high pressure mercury lamp power supply.
Please perform the lamp centering referring to both the procedure listed
below and the instruction manual of the super high pressure mercury lamp
power supply.
1
Turn on the lamp.
Refer to the instruction manual of the super high pressure mercury lamp
power supply for details.
2
Put the filter cube for the fluorescence microscopy in the
optical path.
Use the filter cube switchover lever to put the desired filter cube for the
fluorescence microscopy into the optical path. (Note that the lamp
centering cannot be performed with the dia-filter cube.)
3
Raise the microscope to its uppermost position.
Turn the coarse focus knob to raise the zooming body to the uppermost
position of the focusing mount.
4
Zoom out the microscope.
Turn the zooming knob so that the zooming magnification becomes
lowest.
