OLYMPUS MICROSCOPE MODEL
FH
The new Olympus
FH
Microscope was made
in
response
to
a wide
demand
for
a microscope
with
perfect
illuminator.
This Microscope, then,
is an improvement on the
highly
popular F Microscope, whose
fine
adjustm-
entis0.0005
mm, and whose heads, stages, and lenses are interchangeable.
The Olympus
FH
Microscope, therefore, is a microscope we can recom-
mend
to
the public
with
pride and confidence. The Olympus Optical Co.,
ltd,.
we
might
add, was established in 1919, and since has been
turning
out
optical
products exclusively.
OUTSTANDING FEATURES
OF
OLYMPUS
FH
MICROSCOPE
1.
Perfect Built·in Illuminator.
Centering need only
be
done once regardless of changes in magnification.
2.
0.0005
mm
Fine Adjustment.
This microscope boasts
an
ultra-sensitive fine adjustment system, which
is
the first of its kind in the world.
Focusing is
easy,
and, what
is
more, the thickness
of
the specimen
can
be
measured
by
the sensitivity scale.
3.
Interchangeability of
Head
and
Stage.
This microscope is available in
any
desired head·stage combination.
Furthermore, the
head
and stage
can
be
changed easily
and
speedily.
4.
Plan
Achromatic Objectives.
The
plan achromatic objectives
haye
been
so
designed that there is no
spherical aberration. Furthermore, the field of photomicrographic work
can
be
widened
by
using
low
magnification

PROCEDURE
FOR
ADJUSTING THE COARSE ADJUSTMENT HANDLE
Generally speaking,
the
coarse
adjustment
nandles
are
tight.
This.ofcourse,
means
that
movement
is heavy.
However.
this
can be remedied easily by
gripping
the
right-and
left-side
handles as
illustrated
and
turning
theminthe
opposite
direction
SImultaneously. In
most
cases,
the
coarse
adjustment
handles
should be
moreorless
tight
rather
than loose.
WORKING DISTANCE AND PAR·FOCAL
The revolving nosepiecetowhich
the

are

has been
so
designed
that
as

The
bright

methodofmicroscopic
examination
can
not
be
used
for
examining
colorless,
transparent
specimens
since such
specimens
lack
contrast.
The phase

equipment,
therefore,
was designedtoprovide
such specimens
with
COntrast and thus
make
examination
of
tivlng
bacteria,

possible.
Two
