bring
the double Cross lines into focus by turning
the diopter
adjustment
ring
@ (Fig. 12) of the viewer.
Adjust
until both Cross lines are clearly dis-
tinguishable
from each other. (Fig. 13)
(5) Turn the focusing
knobs
until both Cross lines and the specimen
are
sharply in focus.
* As focusing
at a low magnification
power requires a special skill, the
use of the FT focusing
telecope
(optional)
is recommended.
Ir Should a bright lighting fixture
be mounted
to the ceiling of the room
where photomicrography
is conducted,
cover the binocular
observa-
tion tubes to prevent
light from entering
the binocular
tubes.
(1) Slide the light path selector
lever Q) to the IN Position
in Order to
set the light path to Video.
(Fig. 14)
(2) Maximize

If the image
does
go out of focus,
repeat
Steps (2) and (3) above
until focus
is maintained
even when
zoomed.
Sr After
focusing
the binocular
tube
beforehand
in accordance
with
the
procedure
listed
in section
q
on
page
4, focus
deviation
due to zooming
will
be virtually
eliminated
simply
by selecting
the Video
light path, minimizing
the zoom
magni-
fication
power
and focusing
with
the tube
length
adjustment
ring.

details regarding
photomicrographic
procedures,
refer to the instruction
manual
for the photomicro-
graphic
equipment
in use.
Sr The photomicrographic
range in relation to the binocular
tube's Observation
range (35 mm film diagonal
line length
in relation
to the diameter
of IOx eyepiece
field of view) is as shown

Although
photomicrography
is possible
over a wide
range,
the field of view
may go slightly
out of focus at the
penphery.
If Photos
perfectly
focused
up to the periphery
are needed,
use Photo eyepieces
with 3.3~
or higher
magnificatron
powers.
* As Vibration
may adversely
affect
photomicrographic
results,
photomicrography
should
be conducted
in a place
subject to minimal Vibration.
Be sure to check that no Vibration
occurs and the image is free from wavering
through
the viewer
before
releasing
the shutter.
