Operation
of
Each
Part
a
Auto-photo
switch
(for
photomicrography)
The
color
temperature
of
the
lamp
varies
according
to
the
voltage.
If
the
voltage
is
high,
the
color
temperature
of
the
lamp
increases
and
the
light
becomes
bluer.
If
the
voltage
is
low,
the
color
temperature
of
the
lamp
decreases
and
the
light
becomes
redder.
Therefore,
to
obtain
the
best
color
reproduction
in
color
photomicrography,
it
is
necessary
for
the
lamp
voltage
to
be
kept
constant.
When
using
daylight-type
color
film,
the
usual
setup
is
to
use
the
color
balancing
filter
(NCB11)
and
set
to
the
standard
lamp
voltage.
‘The
auto-photo
switch
is
used
to
automatically
set
the
standard
lamp
voltage.
If
the
images
on
color
film
shot
with
the
auto-photo
switch
on
are
reddish
or
bluish,
finely adjust
the
voltage
with
the
auto-photo
voltage
selection
switch.
The
standard
position
for
the
auto-photo
voltage
selection
switch
with
four
levels
is
the
second
index
dot
from
the
innermost.
Sliding
the
switch
forward
increases
the
bluish
tint
of
the
light,
while
sliding
the
switch
towards
the
back
increases
the
reddish
tint
of
the
light.
Use
commercially
available
color
compensation
filters
(CC
filters)
if
this
adjustment
does
not
resolve
the
problem.
These
objectives
are
used
with
the
immersion
oil
applied
between
the
specimen
and
the
tip
of
the
objective.
The
immersion
oil
is
provided
for the
microscope.
Bubbles
in
the
oil
will
adversely
affect
the
viewing
of
the
image,
so
be
careful
to
prevent
the
formation
of
air
bubbles.
To
check
for
air
bubbles,
remove
the
eyepieces,
fully
open
the
field
and
aperture
diaphragms,
and
look
at
the
exit
pupil
of
the
objective
within
the
eyepiece
tube.
(The
exit
pupil
will
appear
as
a
bright
circle.)
When
it
is
difficult
to
see
if
there
are
any
bubbles,
mount
a
centering
telescope
(sold
separately)
on
the
eye;
sleeve
with
an
adapter
(sold
separately).
Then,
while
turning
the
eyepiece
on
the
centering
telescope
to
change
the
focus.
look
through
the
centering
telescope
for air
bubbles.
If
there
are
bubbles
in
the
oil,
remove
them
by
one
of
the
following
methods:
“
Turn
the
revolving
nosepiece
slightly,
moving
the
oil-immersed
objective
back
and
forth
once
or
twice.
*
Add
more
oil.
*
Remove
the
oil
and
replace
it
with
new
oil.
Use
as
little
oil
as
possible
(just
enough
to
fill
the
space
between
the
tip
of
the
objective
and
the
specimen).
If
too
much
oil
is
applied,
the
excess
will
flow
onto
the
stage.
