12.6 Use of the shutter

• The microscope is equipped with a shutter
① located on the right side of the fluorescent
illuminator. (Fig. 51)
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.
(Switching off and switching on frequently the
HBO lamp considerably reduces its duration).
• This precaution is not necessary in the case
of the LD1 and LD2 models: the LED can be
switched on and off without any problem.
