I INSTRUCTION MANUAL I
MODELS VMF,VMT&VMZ
OLYMPUS

This instruction manual has been written for the use of the Olympus Stereo Microscopes Models
VMF, VMT and VMZ. lt 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.
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.
11 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. lt is best to keep
lenses in a desiccator, containing silica gel.

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

*NOTE:
As this screw can also be

you can choose a better
position
for mounting the
incident
illuminator so that
it does not block your
smooth operation.

V. 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.
1. 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)
2. Specimen on the Stage Plate
Place a specimen in
the center of the stage plate and
clamp it with the stage clips, if necessary. (Fig. 2)
3. 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)
4. Diopter Adjustment
Fig. 1
Fig. 2
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 or Model VMZ. ascertain that the high magnification
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 CD to focus on the specimen, without using the focusing knobs. (Fig. 4)
Fig. 3
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 is provided with two objective pairs. Rotate the turret until the objective
pair of your choke is engaged.
In case of the Model VMZ, 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
a) Water sealed light exits on the base prevent damage from water spi!ls.
b) lt provides even illumination with all objective powers except the auxiliary lens
VM-AL 0.5X.
c) If light intensity is too high, it can be reduced by placing a 45mm-diameter NO filter
on the light exit on the base.
