condenser
The
top
lens
of
the
swing-out
condenser
can
be
moved
outside
the
optical
path
with
the
swing-out
knob.
During
normal
orthoscopic
microscopy
or
conoscopic
microscopy,
the
top
lens
is
used
while
positioned
in
the
optical
path.
During
orthoscopic
microscopy
using
a
low-power
objective
of
4x
or
lower,
swing
out
the
top

color,
swing
out
the
top
lens
(the
condenser
aperture
diaphragm
may
be
stopped
down)
and
illuminate
with
light
that
is
as
parallel
to
the
optical
axis
as
possible.
The
field
diaphragm
restricts
illumination
to
the
area
on
the
specimen
being
viewed.
Turning

changes
the
size
of
the

diaphragm.
For
normal
observation,
the
size
the
diaphragm
should
be
slightly
larger

and
reducing
the

image.
The
