Use of the shutter:
►
The microscope is equipped with a
shutter ① located on the right side of
the fluorescent illuminator. (Fig.50)
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.
