oil-immersion
operation
o
(using
an
oil-immersion
type
of
objective
and
condenser)
An
objective
marked
“Oil”
is
an
oil-immersion
type.
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.
To
get
maximum
performance
from
an
oil-immersion
type
of
objective
with
a
numerical
aperture
of
1.0
or
greater,
an
oil-immersion
type
of
achromat/aplanat
condenser
must
also
be
used.
These
con-
densers
are
used
with
oil
applied
between
the
specimen
and
the
condenser
lens.
Bubbles
in
the
oil
will
adversely
affect
the
viewing
of
the
image,
so
be
careful
to
prevent
the
forma-
tion
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
eyepiece
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.
(In
the
case
of
the
condenser,
gently
turn
the
condenser
focus
knob
to
move
the
condenser
up
and
down
slightly.)
*
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,
or
between
the
tip
of
the
condenser
and
the
specimen).
If
too
much
oil
is
applied,
the
excess
will
flow
onto
the
stage
and
around
the
condenser.
