OLYMPUS MICROSCOPE MODEL FH
The new Olympus FH Microscope was made in response to awide
demand
for amicroscope with perfect illuminator. This Microscope, then,
is an improvement on the
highly popular FMicroscope, whose fine adjustm-
ent is 0.0005 mm, and whose heads, stages, and lenses are interchangeable.
The Olympus
FH Microscope, therefore, is amicroscope 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 plan aChromafic objectives.

STRUCTURE OF PARTS
A. MICROSCOPE BODY
Arm, Focusing Mechanism and Condenser:
The arm is secured firmly to the base by means of a support, and. in turn, it supports such
parts as the focusing mechanism, stage. condenser, revolving nosepiece and the head. furthermore.
It is shaped uo facitrtate carrying around.
The focusing mechanism has such built in unrts 35 the coarse adjustment and fine adjustment
units and the coarse adjustment stopper. The coarse adjustment handle and the fine adjustment
handle are coaxial. In other words. the large handle is used for coarse adjustment and the small
handle for fine adjustment. The stage will move nO hIgher than the height obtained by manipul
ating the coarse adjustment handle, provided that the coarse adjustment stopper is tightened.
In othe words. when the stage is lowered and again brought up toward the objecti\le. it will go
no higher than the stop position. This not onl)l pre~ents contact of the specimen and the objective
but also facilitate5 focusins. The condenser mount. which i5 of the rack-and-plnlon type, has it
recei~er with a dovetail groove. ThB condenser mount l:;crew is used for adjusting the optIcal axis.

B. MICROSCOPE HEAD
The mitroscope head of Model EH microscope is inclined 45 degrees from the horizontal plane
so as to enable microscopic examination in the most natural posture and with is minimum of fatigue.
As mentioned previously, the standard height of this instrument Is 380mm from the desktop.
This is ex.actly the height required for the average person to conduct microscopic examination In
the
most natural sitting posture, Thus, aspecial desk is abSOlutely unneceSSary when this MOdel
EH microscope is used.
The following four types of microscope h~ad are
available;
1. Binocular head (Bi)
2. Trinocular head (Tr)
3. Upright head for photomicrography
4. Monocular head
To mount the mu;:roscope head, turn the
knurled rinB of the microscope fix.ing screw.
This witt fix the head properly to the arm and;
at the sam~ time, secure precise optical align-
ment.

The light from the objective reach@$ the eyepieces after being split into two by the semi.
transmissIve prism. This head was designed taking Into consideration the Characteristic function
of the human eyes_
That is to say. the right and left optical axis are slanted slightly toward the center. Furthermore,
the eyepieces can be adjusted according to the user's inter-pupillarv distance. This is done by
sHpping out the dovetailed eyepieces. The inter-pupillary distance Is shown On the scale between
the two eyepieces. This operation is carr@d eye-width adjustment. The scale readinBs are based
on BiWF lOX eyepie:ces. Since one e~e is often weaker than
the other, this tube is equipped with a diopter adjustment
ring on the left eyepiece. When the dioptric adjustment ring
is set at 2.ero, and the inter-pupillary distance scale reads
62, the mechanical tube measures aDoul 160mm long.

B·2 Trinocular Body
The trinocular head consists of binocular head and upright head for photomic.rography. The
photo,trapller can actually see what he is photographing since it inCO(PO~iJtes a mechanism to
switch the light pateh alternately for direct observation and photomicrographic work. The binocular
head is equipped with iJ dioptric adjustment ring and an Inter-pupHlary distance scale,

A PUSh in of the knob almost instantly returnS
the prism to its original position (@ diagram).
ThIs unique mechanism (one-knob operation)
permits direct observation and photomicrographic
work alternately with aminimum loss of time.

Upright head for photomicrography
In case of microscopes featuring monocular
inclined head or binocular head, the standard
microscope head must be interchanged with
an upright head when conducting photomicro·
graphic work. The photomicrographic appara·
tus must be mounted on this upright head.

C. STAGE
There Ire four types of stages available for- Model F'H:
oSquare coaxial mechanical stage (double handle) FS:
oSquare revolving coaxial mechanical stage (single handle) erS
oSquare coaxial mechanical stage (single handle) CS
oRound revolving stage RS
The square cOClxial mechanical stage fS is standard equipment of the fH Microscope.
C·l Square Coaxial Mechanical Stage FS
ThIs square stage can be detached at will since it is dovetailed to the main body. The specimen
can be moved by means of handles found on both sides of the stage. For forward and backward
movement of the specimen, a large handle (raCk-aod-pinion) is used, and a small handle (lead
screw) is used for lateral movement Th{J surface of the stage can be made level bY removing
the Clip.
Two slide glasses can be placed on the specimens side by side. This is extremely convenient
when comparing two specimens at the same Ume.
