CENTERING THE LIGHT BEAM
First allow the mercury vapor lamp at least five
minutes to fully illuminate for optimal use (it is very
important to allow the system enough time to fully
ignite in order to achieve a fully illuminated centering
beam).

When the lamp is fully illuminated,
a beam of light is
visible through the eyepieces in the field of view
.
To center this beam of light in the field of view, two
centering knobs are located on the lamp housing as
indicated by the two arrows (A & B) in Fig.
9
. By
adjusting these two knobs, the focused beam will
shift. Adjust the
beam position to the center of the
field of view as
s hown in Fig . 9. A.

Turn the power supply ON. Allow the lamp at least 5 minutes to
fully illuminate for optimal use.
The halogen illumination of the microscope should be kept off
while working with FLR
.
Place the specimen slide on stage. Select the excitation light by
installing the filter block as follows :
For G-excitation - Install red sliding block to its outermost position.
For B-excitation - Push blue sliding block in to its innermost position.
For O light (non-excited light) - Slide out the filer to parking point.
Observe the specimen slide through the microscope's eyepieces.
When no fluorescent light is required, turn the attachment's power
supply OFF and set the sliding filter block to its middle / neutral
position. To view the specimen in normal condition under the
microscope's light, turn the microscope ON.
