Manipulate two centering screws until the image of the illumination
field
diaphragm comes to the center.
You need not mind about a slight deviation from this centering caused
by switching
over
to other objectives because this will not produce
any objectionable result.

Observation
For usual case of observation with objectives from 4X to
lOOX
(oil-immer-
sion), it suffices to leave the change-over lever at the position L. When an
exact illumination or extreme brightness is required, as is the case with
photomicrography, it is necessary to make adjustment for each magnifi-
cation by switching
over
the lever.
7.
Photomicrography
Make exact adjustment, depending upon the magnification of the objec-
tive being used, by switching the change-over lever as below:
Objective magnification 4X
10-20X
40-lOOX
Position of the change-over lever L

When using an objective 3X or lower, set the change-over lever to H
and replace the condenser with the one specifically designed for lower
magnification.
The illumination for the Model L-Ke will not change its color temper-
ature by the change-over above mentioned.

Other
Light
Sources
When using any other
light
source outside of
the
microscope, replace
the
illumination field
lens with the
accessory
reflecting
mirror, as
shown in Fig. 12.

Filter
Case
A filter of the diameter
45mm
can be mounted on the illumination field
—15—
lens. A filter of the diameter
33mm
can be placed in the condenser or
in
the filter case of the microscope.
This
filter case to be attached onto
the
microscope base is available on order.
FOCUSING
1.
Focusing
Adjustment
The microscope model L-Ke is provided with coaxial, coarse and fine
focusing knobs, both of which are located near the microscope base (Fig.
13).
Forward rotation of either of the focusing knobs by the operator raises
the
microscope stage and vice
versa
(Fig. 13, 14).
2.
Eyepiece
Adjustment
When using a binocular or trinocular eyepiece tube for observation the
adjustment
of the user's eye-sight (diopter) discrepancy between the
right
and left
eyes
is necessary which is made by rotating the adjusting
ring
on the lefthand eyepiece.
After focusing with
your
right eye by raising or lowering the microscope
stage, turn the adjusting ring left or right to obtain the sharp image with
your
left eye, too. Then, regulate the interpupillary distance of the bino-
cular or trinocular tube by sliding the eyepieces left or right by means of
the
knob (Fig. 15), until the viewfields of both eyepieces merge together.
It
will be advantageous to memorize the attained diopter and inter-
pupillary distance readings for future use.
The red dot engraved on the interpupillary distance scale indicates the
position where the mechanical tube length becomes exactly
160mm.
The
HK (high eyepoint type) eyepieces have an eyecup on top, the rotation of
