14.7 Use of the shutter

The epi-illuminator is equipped with a shutter
on the right side of the fluorescent illuminator. (Fig. 52)
1. Close the shutter by interrupting the observation for a limited
time and not subjecting the sample to unnecessary lighting in
the period in which it is not observed.
(Frequently switching off and on the HBO bulb considerably
reduces its lifetime).

14.8 Use of the light excluding plate

Microscope is provided with a light excluding plate
that can be placed on the stage and prevents flare and
reflections coming from the condenser front lens.
The plate can be used in two different ways.
1. Mode n° 1: place the plate on the stage (under the slide
holder) and place the slide directly over the plate. (Fig. 53)
2. Mode n° 2: lower the condenser and insert the plate between
the two layers of the stage. (Fig. 54)
In both cases it is possible to move the sample using the
stage X-Y translation knobs.
