1. After the equipment has been used in an observation of a specimen that
is accompanied with a potential of infection, clean the parts coming in
contact with the specimen to prevent infection.
· Moving this product is accompanied with the risk of dropping the
specimen. Be sure to remove the specimen before moving this
product.
· In case the specimen is damaged by erroneous operation, promptly
take the infection prevention measures.
· The product becomes unstable if its height is increased by an accessory
mounted on it. In this case, take anti-toppling measures to prevent the
specimen from being dropped when the product topples down.
2. Install the microscope on a sturdy, level table or bench so as not to block
the air vents on the underside of the base.
Do not place the microscope on a flexible surface, as this could result in
blocking the air vents and cause overheating or a fire.
3. The surfaces of the lamp housing on the rear of the microscope will
become extremely hot during operation. When installing the microscope,
make sure to allow ample free space (10 cm or more) around and in
particular above the lamp housing.
4. When installing the microscope, route the power cord away from the
lamp housing. Should the power cord come in contact with the hot lamp
housing, the power cord could melt and cause electric shock.
5. To avoid potential shock hazards and burns when replacing the light
bulb, set the main switch @ to “

1 Replacing the Fine Adjustment Knob
|
@²³
#The fine adjustment knob has been attached on the right side at the
factory.
}The fine adjustment knob is designed detachable to prevent interference
with hand during manipulation of the fine adjustment knob or X-/Y-axis
knobs.
Usually attach the knob on the opposite side to the X- and Y-axis knobs.
1. Using the Allen screwdriver, loosen the clamping screw @ and remove
the fine adjustment knob ².
2. Remove the seal from the fine adjustment knob screw hole on the other
side and attach the knob by reversing the removal procedure.
3. Attach a provided seal on the screw hole | of the removed fine adjustment knob.
}The fine adjustment dial ³ can be operated with your fingertip or finger
surface at the same time as manipulating the X- or Y-axis knob.
Adjusting the Coarse Adjustment
2
Knob Tension
#Adjust the coarse adjustment knob tension using the tension ad-
justment ring @.
The coarse adjustment knob tension is preadjusted for easy use. However, if desired, you can change the tension using the tension adjustment ring @. Turning the ring in the direction of the arrow increases
tension, and vice versa.
The tension is too low if the stage drops by itself of focus is quickly lost
after adjustment with the fine adjustment knob. In this case, turn the ring
in the direction of the arrow to increase tension.
(Fig. 11)
(Fig. 12)
@
Fig. 13
3 Pre-focusing Lever
}The pre-focusing lever ensures that the objective does not come in con-
tact with the specimen and simplifies focusing.
After focusing on the specimen with the coarse adjustment knob, turn
this lever @ in the direction of the arrow and lock; the upper limit on
coarse adjustment movement is set at the locked position.
After changing a specimen, refocusing is easily accomplished by rotating the coarse adjustment knob to reach the pre-focused position, then
making fine adjustments with the fine adjustment knob.
}Stage movement with the fine adjustment knob is not locked.
#When the pre-focusing lever is locked, a coarse movement stroke is
reduced due to the microscope’s mechanism, causing the stage
not to be able to be lowered to the lower limit. To lower the stage to
the lower limit, release the pre-focusing lever.

1 Placing the Specimen
#The dimensions of the slide glass should be 26 x 76 mm with thick-
ness of 0.9 to 1.2 mm, and the cover glass should have thickness of
0.17 mm.
#When observing very large specimens, remove the slide holder and
place the specimen directly on the stage.
Microscopy with Double-Slide Holder (Fig. 14)
1. Turn the coarse adjustment knob @ to lower the stage.
2. Open the spring-loaded curved finger ² on the slide holder and place
one or two specimen slides on the stage from the front.
3. After placing the sides as far as they will go, gently release the curved
finger.

Using an Oil Immersion Objective
Adsorption of immersion oil can cause the specimen to drift. In such
cases, it is recommended to use the optional BH2-SCB-3 specimen clip
³ for oil immersion objectives. (Fig. 16)
Using an Oil Immersion Condenser
It may be effective to use the optional U-SVRO (right-hand knob) or USVLO (left-hand knob) slotted stage which prevents close contact between the specimen and stage.

adjustment knobs.
2. Turning the X-axis adjustment knob ³ or Y-axis adjustment knob | clockwise (in the direction of the arrow) increases the tension and counterclockwise decreases it.
#If the tension is adjusted to tight, a creaking sound may be heard
during stage travel, and the stage stopping accuracy may be imperiled.
CAUTION
[Treatment]
Horizontal direction: Hold the specimen holder and move the stage guide
Vertical direction: Hold the upper stage and move it to the front and rear
Stage Feed Knob Rubber Caps (Optional)
}When the X- and Y-axis knobs are fitted with the rubber caps, the knobs
can be adjusted without slipping and fine adjustment is possible by
holding the knobs with a very light force. The knob rubber caps also
reduce fatigue after long hours of operation.
The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness
2 mm) knob rubbers are available.
To attach the knob rubbers:
First fit the larger knob rubber to the Y-axis (upper) knob from below it,
then fit the smaller knob rubber to the X-axis (lower) knob from below it.
After long hours of use, the stage guide may be deviated and the stage travel range may be decreased.
However, this is not malfunction and can be corrected
easily as described below.

Adjust the diopter as instructed above.
However, since no diopter adjustment ring is provided, turn the top of
the eyepiece instead.
3 Using the Eye Shades
When Wearing Eyeglasses
Use with the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When Not Wearing Eyeglasses
Extend the folded eye shades in the direction of the arrow to prevent
extraneous light from entering between the eyepieces and eyes.

4 Using the Eyepiece Micrometer Disk
When the WHN10X-H (or WHN10X) eyepieces are used, an eyepiece
micrometer disk can be inserted in one of them. When the eyepiece
does not have a diopter adjustment mechanism, however, it is hard to
focus on the micrometer disk if the operator has poor eyesight. Should
that be the case, adjust the focus with eyeglasses on.
Use 24 mm dia. x 1.5 mm thick micrometer disks.
Following Fig. 25, turn the built-in micrometer-mounting frame ² counterclockwise to remove it from the eyepiece and place a micrometer disk.
Screw the micrometer mounting frame back into the eyepiece sleeve.

6 Adjusting the Tilt (with the U-TBI3)
}Adjust the height and tilt of the observation tube to obtain the most com-
fortable viewing position.
Holding the binocular section with both hands, raise or lower it to the
desired position.
#Never attempt to force the binocular section past the upper or lower
stop position. Applying excessive force could destroy the limiting
mechanism.
}The U-TBI3 can be used in combination with only one intermediate at-
tachment.
}If you need photography using the U-TBI3, use the U-TRU trinocular tube.
With the U-ETBI/U-TTBI (Fig. 28)
The U-ETBI and U-TTBI are ergonomic observation tubes with normal
field, capable of the tilting adjustment as well as the adjustment of the
eyepiece position toward the front and rear (by 45 mm). The U-ETBI is the
erect image model and the U-TTBI is the inverted image model, and
both models are of the same size.
#The intermediate attachments that can be combined with the
U-TTBI are limited. For details, please contact Olympus.

5. Turn the two condenser centering screws ³ to move the iris diaphragm
image to the center of the field of view.
6. Gradually open the field iris diaphragm. The condenser is properly centered if the iris image is centered and inscribed in the field of view.
7. During actual use, open the field diaphragm slightly until its image circumscribes the field of view.
(Figs. 29 & 30)
18
Effects of Field Iris Diaphragm (Fig. 30)
The field iris diaphragm restricts the diameter of the beam of light entering the objective and thus excludes extraneous light, improving image
contrast. The diameter of the field iris should e adjusted for objective
power to the extent that it just circumscribes the field of view. (See “Compatibility of Objectives and Condensers” on the next page.)

Aperture Iris Diaphragm (Figs. 31 & 32)
· The aperture iris diaphragm determines the numerical aperture of the
illumination system. It has an effect of adjusting image resolution and
contrast. Stopping down the aperture iris diaphragm increases the depth
of focus.
· Since the contrast of microscope specimens is ordinarily low, setting the
condenser aperture iris diaphragm to between 70 and 80% of the N.A. ²
of the objective in use is usually recommended.
Adjust the ratio by removing the eyepiece and looking into the eyepiece
sleeve while adjusting the aperture iris diaphragm ring @ until the image
shown in Fig. 31 is seen.
}Using the numerical aperture scale:
You can use the condenser numerical aperture scale by adjusting the
aperture iris diaphragm ring @. (Fig. 32)

3-6 Immersion Objectives
#Be sure to use the provided Olympus Immersion oil.
Fig. 33
1 Using Immersion Objectives
1. Focus on the specimen with objectives in the order of lower-power to
higher-power ones.
2. Before engaging the immersion objective, place a drop of provided
immersion oil onto the specimen at the area to be observed.
3. Turn the revolving nosepiece to engage the immersion objective, then
focus using the fine adjustment knob.
#Since air bubbles in the oil will affect the image quality, make sure
that the oil is free of bubbles.
a. To check for bubbles, remove the eyepiece and fully open the field and
aperture iris diaphragms, then look at the exit pupil of the objective inside
the observation tube. (The pupil should appear round and bright.)
b. To remove bubbles, turn the revolving nosepiece to repeatedly defocus
and refocus the oil immersion objective.
}If the condenser engraving shows a numerical aperture (NA) of 1.0 or
higher, the number applies only when oil is applied between the slide
glass and the top surface of the condenser. When oil is not present, the
NA is about 0.9.
4. After use, remove oil from the objective front lens by wiping with gauze
slightly moistened with an ether (70%)/alcohol (30%) mixture.
Caution in use of immersion oil
If immersion oil enters your eyes or contacts with your skin, immediately
take the following treatment.
Eyes: Rinse with fresh water (for 15 minutes or more).
Skin: Rinse with water and soap.
If the appearance of the eyes or skin is altered or pain persists, immediately see your doctor.

3-7 Objectives with Correction Collar
}If the cover glass thickness is not 0.17 mm, the objectives cannot mani-
fest their performances. If a correction collar equipped objective is used
in this case, the difference in thickness can be compensated for by adjusting the collar.
Adjustment Procedure
· If the cover glass thickness is known, set the correction collar @ to that

value. (Fig. 34)
· If the cover glass thickness is unknown, adjust the correction collar @
and fine adjustment knob alternately until the positioning with the highest resolution is obtained.
#Be careful not to touch the correction collar @ when turning the
revolving nosepiece.

and Power Cord
Cables and cords are vulnerable when bent or twisted. Never subject them to excessive force.
Make sure that the main switch @ is set to “ ” (OFF) before connecting the power cord.
1. Connect the lamp housing cable connector ² into the connector ³ on
the rear of the microscope.
(The BX51TRF/BX52TRF have two connectors on the rear panel. With
these models, the connector from the transmitted light lamp housing
should be connected to the connector marked and that from the
reflected light lamp housing to the connector marked .)
Always use the power cord provided by Olympus. If no power cord
is provided with the microscope, please select the proper power
cord by referring to section “ PROPER SELECTION OF THE POWER
SUPPLY CORD ” at the end of this instruction manual.
2. Connect the power cord plug | to the AC receptacle 5.
The power cord should be connected to a grounded/earthed ,3conductor power outlet. If the power outlet is not grounded/earthed
properly, Olympus can no longer warrant the electrical safety performance of the equipment.
3. Plug the power cord plug 6 into the wall outlet 7.
Should the power cord come in contact with the hot lamp housing,
the power cord could melt and cause electric shock. Be sure to
route the power cord away from the lamp housing.
