OLYMPUS

This instruction manual has been written for the use of the Olympus Stereo Microscopes Models
VMF-W, VMT-W and VMZ-W. It is recommended that you read the manual carefully in order to
familiarize yourself fully with the use of the microscope so that you can obtain optimum
performance.
VII. USE OF OPTIONAL ACCESSORIES
IMPORTANT
Operation
1. Always handle the microscope with the care it deserves and avoid abrupt motions.
2. Avoid exposure of the microscope to direct sunlight, high temperature, high relative
humidity, dust and vibration.
Maintenance
1. Lenses must always be kept clean. Fine dust on lens surfaces should be blown or wiped
off by means of an air blower or gauze. Carefully wipe off oil or fingerprints deposited
on the lens surfaces, with gauze moistened with a small amount of xylene, alcohol or ether.
2. Do not use organic solutions to wipe the surfaces of various components. Plastic parts,
especially, should be cleaned with a neutral detergent.
3. Never disassemble the microscope for repair.
4. The microscope should be stored in its container immediately after use. If this is not
possible, it should be covered with the vinyl dust cover provided. It is best to keep
lenses in a desiccator.

I. © MAIN CHARACTERISTICS
The VM Series Stereo Microscopes include three types of stereomicroscope bodies —
VMF-W, VMT-W and VMZ-W. The Model VMF-W is provided with one objective pair built
into the binocular stereomicroscope body, and the Model VMT-W with two parfocal objec-
tive pairs in a turret built in the microscope body, while the Model VMZ-W features a con-
tinuously variable zoom system objective control in the body.

OPERATION
The stage plates fit into the circular opening in the base. The clear plate can be used for
both reflected and transmitted illumination. Colored background can be achieved by
placing suitable material beneath the plate, for contrast, etc. The frosted plate is used
with reflected illumination, The plate is frosted white on one side, and black on the
other. If the specimen is white or brightly colored, use the black side of the plate to
increase image contrast by darkening the background. For dark or black specimens, reverse
the plate with the white frosted side facing the objective.
Tension Adjustment of Focusing Knobs
This focusing mechanism makes its motion freely
adjustable for either heavy or light movement
depending on the observer's preference. To adjust
the tension hold the two focusing knobs with both
hands and slightly rotate them in the opposite
directions, at the same time. (Fig. 1)
Place a specimen in the center of the stage plate and
clamp it with the stage clips, if necessary. (Fig. 2)
Interpupillary Distance Adjustment
Hold the right and left eyepiece tubes with both
hands and push or pull the tubes in the arrow
directions until perfect binocular vision is obtained.
(Fig. 3) Fig. 2
. Diopter Adjustment
a) Looking through the right eyepiece with your right eye, focus on the specimen with
the focusing knobs.
NOTE: In case of the Model VMT-W or Model VMZ-W, ascertain that the high magnifica-
tion objectives are used for this adjustment:
b) Look at the image through the left eyepiece with your left eye, and rotate the diopter
adjustment ring @ to focus on the specimen, without using the focusing knobs. (Fig. 4)
NOTE: If accurate interpupillary distance and diopter adjustments are not accom-
plished, prolonged observation would put considerable strain on the observer's
eyes.

5. Objective Changes
The Model VMT-W is provided with two objective pairs. Rotate the turret until the objec-
tive pair of your choice is engaged.
In case of the Model VMZ-W, rotate the zoom control ring until you obtain the desired
magnification within the magnification range.
6. Use of Eyeshields
Eyeshields are recommended to prevent glare and loss of contrast caused by ambient
light hitting the eye.
7. Use of the Reflected and Transmitted Illumination Base VM-ILA-2
a) Water sealed light exits on the base prevent damage from water spills.
b)
It provides even illumination with all objective powers except the auxiliary objective
VM-AL 0.5X.
c) If light intensity is too high, it can be reduced by placing a 45mm-diameter ND filter
on the light exit on the base.

© Bulb Replacement
* Before bulb replacement, be certain the defective bulb is
cool.
1) Pull the contact pins of a halogen bulb from its polyethylene
bag.
* Be careful not to leave fingerprints or smudges on the
bulb portion.
2) Insert the contact pins fully into the socket ©. (Fig. 6)
* Do not exert force to twist or bend the bulb, but gently
push the pins into position.
* Do not tilt the bulb when inserting it into the socket.
%* Take care not to smudge the mirror surface (2) with
fingerprints, etc. If smudged, the mirror should be wiped
clean with cotton gauze slightly moistened with a 3:7
mixture of alcohol and ether.
3) Looking at the bulb from the front, confirm that the fila-
ment image covers the lower half of the screw head on the
mirror surface, (Fig. 7)
* If the filament image is deviated horizontally from the
center (since the bulb tilts in either direction), adjust the
bulb position correctly.
* If the filament image is deviated vertically, the contact
pins are not inserted completely. Push them in completely.

C. Epi-Illuminator LSGA
The Model LSGA © is connected to the transformer TL-2 and can be mounted on the
microscope stand or clamped to the transformer by means of a mounting arm for incident
illumination. The epi-illuminator LSGA is provided with two 6V 15W halogen bulbs, a trans-
former TL-2 and mounting arm ICH ©.
The
light intensity of the epi-illu-
minator is adjusted by means of
the voltage adjustment knob on the
transformer or on the illumination
base VM-ILA (3-4-5-6V).
