The MEIJI EM Series (EMF,EMT, EMTR and EMX Series) Widefield Stereo Microscope consists of two
converging compound microscopes which are combined as a unit to focus simultaneously on the same
field of object. Each body tube is fitted with a set of Porro prisms to erect the image and matched
achromatic objectives and super widefield eyepieces to furnish a very wide flat field of view. Each eye
observes the object from a different perspective, consequently, deep stereoscopic relief is produced in
the fused image.
This MEIJI EM Series Stereo Microscope widely is used for various applications such as assembly and
inspection of semiconductor devices, and as an indispensable part in bonding machines and
microtomes, as well as for educational, clinical and research purposes.
This series stereo microscope is used as follows:
UNPACKING
This EM series stereo microscope is usually supplied in a styrofoam containers. Remove the
instrument from its container by grasping the stereo microscope body and supporting the base with the
other hand.
Place the instrument on a firm flat table. (No packing material should be discarded until the instrument
has been checked, since some may contain accessory equipment which can not be attached to the
instrument.)
When supplied in a wooden cabinet, remove the instrument from the cabinet by unscrewing the two
large screws which are used to fasten the instrument to the cabinet through the bottom of the cabinet,
with a coin or large screwdriver.
If you ordered zoom stereo body and stand separately, loosen the set screw and insert the body into
the holder then tighten the set screw after setting at the desired position.
How to Rotate the Head:
A special feature of this series stereo microscope is the rotation of the stereo
microscope body through 360°so that it can be utilized either in the conventional
position or with the stage nearest to the observer. To rotate the stereo microscope body,
loosen the set screw.

IMPORTANT!
Before plugging the illuminator into any electric
outlet, make sure that transfomers and illumination
bases supplied to you are suitable to the current
available. (When shipped, these will be labelled as
to mains voltage and cycles specification.)

MAINS AC100V-120V
FOCUSING CAPABILITY
The Pole-type focusing stands have a double
focusing capability, i.e. Rough Focus (by
sliding the whole focus assembly and stereo
body up and down on the pillar, fixing the clamp
screw when in approximate focus on your
specimen), Precise Focus (by using the rack
and pinion focusing knob).
The focusing stands, P, PL, PX, PC, PB, PBH
and BX are the Pole-type.
Before moving the whole focus assembly up and down for rough focus, loosen
pillar collar once and make sure to reset after the rough focusing is done.
How to use selector switch and dimmer
switch
Focusing stands, PBH, ABH and ABE, are using
6V 10W Halogen lamps with suitable
transformers built-in base and a selector switch
and a dimmer switch on the base.
Select an illuminator to use, either incident or
transmitted, by the selector switch in the way
described above. Then, turn the dimmer switch
knob slowly to clockwise to turn the dimmer
switch ON and to increase brightness. Turn the
knob to counterclockwise to decrease the
brightness and to turn OFF.

The Rigid arm type focusing stands (except the
model ABE) have a focusing capability only by
rack and pinion adjustment. This means that the
available range of specimen sizes/depths which
can be accommodated is somewhat less than in
the case of Pole-type stands.
The Rigid arm type ABE focusing stand is with
integral focus block and extendable working
distance. Provides transmitted and incident
halogen illumination.
To extend working distance,
loosen the clamp screw and
extend the arm upward and
set the screw back.
A, AB and ABH stands
are rigid arm type
focusing stands.

Look through the right eyepiece and, using only the right eye, focus on a plain surfaced objective
centered on the stage. Adjust the focusing knob until the image is sharp without disturbing the focusing
knob.
Look through the left eyepiece and, using only the left eye, adjust the Eyepiece Adjusting Ring, clockwise
or counterclockwise, until the image is in sharp focus.
Each observer must focus the microscope to his individual requirements. However, a change of
specimen requires only a slight readjustment of the focus.
(1)
(2)
(3)
An alternate scheme for focusing may be used. Instead of closing either eye, the left or right side can be
blocked off by holding a bit of opaque material below one side or the other of the eyepiece, and the same
basic procedure followed as above.
Focusing Procedure
When replacing stage plate loosen the set screw
which is visible in front of the stage.
PRECISE FOCUS ON SPECIMEN
Stage Plates
You should now decide which of the stage plates supplied will be most suitable.
The focusing stands with plain bases, P, PL, PX, PC and A, are supplied with reversible black and white
stage plates. Your selection depends on which side, black or white, gives the best contrast conditions with
your selected specimen.
The focusing stands with transmitted illuminators, PB, PBH, AB, ABH and ABE, are supplied with clear
glass stage plates and reversible black and white stage
plates. If the specimen is semi-transparent, the glass stage
plate shoud be used with transmitted illumination switched
on. If the specimen is opaque, use the black/white stage.
Your selection depends on which side, black and white, gives
the best contrast.

Interpupillary Distance Adjustment:
The distance between the eyepiece tubes
can be adjusted to the proper interpupillary
distance of the observer. Take the both sides
of Prism Houses in your hands and move
inward and outward, looking through the
eyepieces, until the both fields are viewed as
Fused.

Changing the Magnification on EMT, EMTR and EMX Models
The EMT, EMTR and EMX models have the paired objectives in a rotatable mount for rapid selection of
magnification. To change the magnification, hold the knurled part of the objective cover and rotate clockwise
or counterclockwise until it clicks and stop.
How to Use Eyeshield
Eyeshields which slip over Super Widefield Eyepieces are supplied. These eyeshields exclude stray light
and orient the eyes in the proper relationship to the eyepieces.

PHOTOGRAPHY
Photographic documentation of microscope visual images is most conveniently achieved by using the
trinocular (photo-binocular) bodies offered for use with MEIJI TECHNO microscpoes.
In the case of the EMTR Stereo series a trinocular is supplied with lever-switching of the image from one of
the binocular eyepieces vertically up to the film plane of a 35mm SLR camera with adaptor mounted on the
vertical photo tube. Visual observation can be simultaneously carried out, using the other eyepiece.
In this system the MA150/50 and MA150/60 Camera Attachment should be used with the SLR camera model
of your choice. Please note that one of the large range of T2 Adaptor Rings suiting to your camera should
have been ordered and supplied.
These adaptor rings are intended to compensate for the small differences in effective distance of the film
plane in your camera - so as to ensure that photographs are optimally sharp, and achieved without wastage
of film in trial shots and experimentation.
In addition special low-power camera eyepieces (2.5X, 3.3X and 5X) are available and recommended -
these will give you maximum field coverage on your specimen while using the convenient and economical
35mm film format

TELEVISION
For television the MA 151/5N "C" Mount Adaptor should be used, threaded into your TV camera, then
placed and adjusted on the upper portion of your trinocular body.
Adjustment can then proceed a per paragraph (3) above. You should understand that the
comparatively large magnification factors inherent in most TV camera/monitor systems will restrict your
fields of view (while blowing up total magnification).
A correct optical set-up and adjustment is, of course, crucial to obtaining a good TV monitor image, but
keep in mind that the monitor controls for brightness and contrast adjustment are also important and
should also be experimented with in order to obtain the best monitor image.
CAMERA OPERATION
(1)
(2)
(3)
Fix your 35mm SLR camera on the MA150/50
or MA150/60 Camera Attachment, then
mounting this assembly on the straight tube of
the trinocular body.
Pull out the lever on your trinocular body so
as to send the image both to the camera and
the visual eyepiece.
Rotate the adjustment ring on the straight
tube so as to set the red indicator line on the
upper tube portion at the top edge of the lower
tube. Then fix in place with the clamp screw.
You now should be set correctly for optimum
conditions of simultaneous visual observation
and photography.

BULB REPLACEMENT
When changing light bulbs in the illuminators, always disconnect the plug from the electrical source.
Never work on the electrical system without first disconnecting.
When a bulb replacement is necessary in the Incident Illuminator, remove the lamp cover by turning it
counterclockwise and remove the old bulb by twisting it 1/3 turn counterclockwise by pushing it toward
the socket so that the bulb will be sprung out from its socket.
To replace the bulb of the Transmitted Illuminator, lay the instrument carefully over on its side and
remove the four set screws in the bottom cover of the base. Replace the old bulb in the same way as
above.
The bulbs used for the Incident and Transmitted Illuminators of PB/AB stand are different. The bulb for
the Incident Illuminator employs a flat filament facing to the head of the bulb and Catalog Number is
MA560 and the bulb for the Transmitted Illuminator employs a flat filament facing to the side of the
lamp and the Catalog Number is MA561. The bulbs used for the Incident and Transmitted Illuminators
of PBH/ABH/ABE stand are same halogen. Catalog number is MA570.
CARE
Always cover the instrument with the plastic dust cover provided when the microscope is not in use.
Keep the eyepieces in the microscope body at all times in order to prevent dust from falling on the
internal optics.
Store the microscope in a safe, clean place when not in use for an extended period of time.
CLEANING
Clean exposed lens surfaces carefully with a pressurized air source, soft brush or clean soft cloth.
Too much finger pressure may damage lens coatings.
To remove oil fingerprints and grease smudges, moisten the cleaning cloth with a very small amount of
alcohol or xylene.
Painted or plastic surfaces should be cleaned only with a cloth moistened with water and a small
amount of detergent.
DO NOT ATTEMPT TO MAKE ADJUSTMENTS TO THE INTERNAL OPTICS OR MECHANICS!!
If the microscope does not seem to be functioning properly or you have questions about its operation,
call your supplier (or an authorized repair service) for advice.
