Focusing
The smaller dial (23.5) is for fine focusing only,
with each scale interval corresponding to a
vertical movement of about 3
µ
m
→
p. 43, the
larger dial is for coarse focusing.
Setting the tube and eyepieces
For trinocular tube* with switchable beamsplit-
ter only: Set beamsplitter at visual observation
by adjusting the rod (37.4). A key to the switching
positions is given in symbols on the side of the
tube.
If wearing glasses you should remove or push
back (Fig. 5) the glare protection on the
microscope, but make sure to use it if you are
not wearing glasses.
For eyepieces with inserted graticule * only:
Bring the object greatly out of focus or remove
from the light path and sharply focus the
graticule with a relaxed eye by adjusting the
eyelens (Fig. 5.4). (The easiest way to relax your
eye is to look at a distant object outside the
room for a moment). Focus the object through
the eyepiece
with graticule only. Then close
your eye and focus the object only by adjusting
the second eyepiece.
Only when no graticule is inserted in either
eyepiece:
When adjusting the eyelens you will see a light-
coloured line (5.5) encompassing the basic part
of the eyepiece. This shows the correct position
of the eyelens for people with normal eyesight
and for spectacle wearers looking through the
microscope with corrective glasses.
Glasses with bifocal or progressive lenses
should be removed before looking through the
microscope.
Only when one eyepiece is without an ad-
justable eyelens: Focus the object exactly
though this eyepiece first (close your other eye),
then focus the image again by adjusting the
eyelens of the second eyepiece.
Set your interpupillary distance by pulling the
eyepiece tubes apart or pushing them closer
together until you see one superimposed image,
not a double image, when you look with both
eyes. Make a note of your personal interpu-
pillary distance, e. g. 65 (22.1).
Close any tube exits you will not be using (35.4;
37.5) as stray light may otherwise disturb
viewing.
Analyser
∗
If the microscope has an integrated analyser
(27.1; 28.1)
→
p. 37, fit or remove as necessary
(after removing the tube or intermediate
system); (only necessary for polarized light!).
A special Pol module* with switchable analyser
and centrable Bertrand lens is available for the
DM LSP polarizing microscope.
