SAFETY PRECAUTIONS

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. If a foreign object is caught during motorized focusing operation, there
will be an error in the focusing block and the motorized focusing opera­tion will be suspended.

Recovery procedure

· If there is no error in motorized operation, the caught object can be
removed by turning the focusing knob.

· If there is an error in motorized operation, the focusing knob becomes
inoperable. Disassemble the relevant modules to remove the caught
object. Replace the relevant modules afterward.

· Turn off the power and then on again. The system will restart unless
there is a malfunction in the motor.

4. To activate temporary stop during focusing operation, turn the focusing
knob (or dial) on the microscope frame (in either direction) or press any of
the FOCUS control buttons ( , , F/C and ESC) (except during PC
communication).
When the main switch of the BX-UCB control box is set to “ I ” (ON), the
focusing operation starts automatically as part of initialization (this opera­tion consists of temporary lowering and then returning to the original
position of the stage). If any of the operations mentioned above is per­formed, an emergency stop will also occur. In this case, set the main
switch to “ ” (OFF) and then “ I ” (ON) again.

5. When lowering the stage by pressing the stage DOWN button @, be
careful not to have your hand caught between the bottom ² of the con­denser and the base.

6. 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.

7. 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.

8. To avoid potential shock hazards and burns when replacing the light
bulb, set the main switch ³ to “ ” (OFF) then disconnect the power cord
from the wall outlet in advance. Whenever you replace the bulb during
use or right after use, allow the lamp housing | and bulb to cool before
touching. (Fig. 2)

1. A microscope is a precision instrument. Handle it with care and avoid
subjecting it to sudden or severe impact.

2. Do not use the microscope where it is subjected to direct sunlight, high
temperature and humidity, dust or vibrations. (For the operating condi­tions, refer to chapter 5, “SPECIFICATIONS”.)

3. When moving the microscope, remove the modules that may drop
including the specimen from the microscope in advance, hold it by the
hand hook on the rear and the base as shown on the left (Fig. 3) and
carry carefully (Weight: approx. 16 kg).

#Before transporting the microscope, be sure to remove the speci-

men, eyepieces and color glass filter so that they will not drop. Also
remove other modules attached to the microscope because they
increase the system weight.

# Damage to the microscope will occur if you grasp it by the stage,

focus adjustment knob or binocular section of the observation tube.

4. The BX61 series can be used with up to two intermediate attachments
including a U-CA magnification changer, U-EPA2 eyepoint adjuster, etc.
For restrictions when using two intermediate attachments, make sure to
read the instruction manuals provided with the respective intermediate
attachments.

2 Maintenance and Storage

1. To clean the lenses and other glass components, simply blow dirty away using a commercially available blower and
wipe gently using a piece of cleaning paper (or clean gauze).
If a lens is stained with fingerprints or oil smudges, wipe it gauze slightly moistened with commercially available absolute
alcohol.

!Since the absolute alcohol is highly flammable, it must be handled carefully.

Be sure to keep it away from open flames or potential sources of electrical sparks –– for example, electrical
equipment that is being switched on or off, which could cause ignition of a fire.
Also remember to always use it only in a well-ventilated room.

2. Do not attempt to use organic solvents to clean the microscope components other than the glass components. To clean
them, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.

3. Do not disassemble any part of the microscope as this could result in malfunction or reduced performance.

eyepiece ² until a clearly defined double crossline can be seen in the
field of view. (Figs. 25 & 26)

2. Looking through the right eyepiece, rotate the coarse and fine focus ad­justment knob to bring the specimen and double crossline into simulta­neous focus.

3. Looking through the left eyepiece with your left eye, turn the diopter ad­justment ring @ to focus on the specimen.

Using an Super Widefield Observation Tube

The operation is similar to the above. However, as the super widefield
tube does not have the diopter adjustment ring on the left sleeve, focus
on the specimen by turning the top of the left sleeve.

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. 28, 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

comfortable 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. However, no intermediate attachment can be combined when
the BX-RFAA or BX-RLAA reflected light illuminator is used.

}If you need photography using the U-TBI3, also use the U-TRU trinocular

intermediate tube.

With the U-ETBI/U-TTBI (Fig. 31)

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.

1 Centering the Condenser

1. Fit the Allen screwdriver @ into the condenser height adjustment screw
and turn the tool counterclockwise to raise the condenser to its upper
limit.

2. Focus on the specimen using the 10X objective.

# When using a swing-out condenser, move the top lens into the light

path.

3. Rotate the field iris diaphragm ring ² in the direction of the arrow so that
the diaphragm image comes inside the field of view.

4. Turn the Allen screwdriver @ to focus on the diaphragm image.

5. Fit the Allen screwdrivers into the two condenser centering screws ³
and turn them 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. 32 & 33)

Fig. 33

Effects of Field Iris Diaphragm (Fig. 33)

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. 34 & 35)

· 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. 34 is seen.

}Using the numerical aperture scale:

You can use the condenser numerical aperture scale by adjusting the
aperture iris diaphragm ring @. (Fig. 35)

3-6 Immersion Objectives

# Be sure to use the provided Olympus Immersion oil.

BX61

Fig. 36

1 Using Immersion Objectives

1. Focus on the specimen using all objectives, starting from the lowest­power objective to higher-power objectives.

2. Press the stage escape button to lower the stage, then 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.

4. Press the stage escape button to raise the stage, then turn the focus
adjustment knob to focus on the specimen.

# 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 toward the shorter ob-

jectives and 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.

5. After use, remove oil from the objective front lens by wiping with gauze
slightly moistened with absolute alcohol.

!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: Rise with water and soap.
If the appearance of the eyes or skin is altered or pain persists, immedi­ately see your doctor.

(Fig. 36)

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. 37)

· If the cover glass thickness is unknown, adjust the correction collar @
and focus 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.

ASSEMBLY

7-1 Assembly Diagram

The diagram below shows the sequence of assembly of the various modules. The numbers indicate the order of assembly.
The BX61TRF microscope frame is assembled in the same procedures.
The module model numbers shown in the following diagram are merely the typical examples. For the modules with which
the model numbers are not given, please consult your Olympus representative or the catalogues.

# When assembling the microscope, make sure that all parts are free of dust and dirt, and avoid scratching any parts

or touching glass surfaces.

Assembly steps enclosed in will be detailed on the subsequent pages.

}Most assembly operations are possible by using the Allen screwdriver ( ) provided with the microscope. How-

ever, the assembly of the reflected light illuminator requires the use of the provided Allen wrench ( ) for clamping the
internal screws (to ensure the performance, we recommend that you have your Olympus representative assemble or
remove this module).

7-2 Detailed Assembly Procedures

# For use in focusing control, only either the Z-board or AF control board can be installed on the BX-UCB.

Installing different boards on it may result in malfunction. When using the AF control board instead of the Z-board,
set the on-board DIP switches on the AF control board to the same settings as the following settings that are
originally intended for the Z-board.

Setup and Installation of the Z-Board

}The on-board DIP switches on the Z-board have been set up for the

BX61 or BX62 (all of switches S1, S2 and S3 are set to OFF).

Changing the Settings of On-Board DIP Switches (Fig. 38)

#Leave all other DIP switches than those mentioned below in the OFF

positions.

}Switch only the DIP switches mentioned below to the ON positions.

S2 No. 4

· This replaces the functions of the F/C switching and stage escape but­tons on the left side of the BX61/BX62 with the stage DOWN and UP
buttons.

S3 No. 1

· This turns off the automatic initialization and sets the remote mode which
is the default.

S3 No. 4

· When the U-FWT filter wheel is not used, this changes the focus adjust­ment stroke from 15 mm to 25 mm.

}When the U-LWUCD long-WD universal condenser is used, set this to

the OFF position.

Mounting the Z-Board (Fig. 39)

}Be sure to set the main switch on the BX-UCB control box @ to “ ”

(OFF) before proceeding to mounting the Z-board.

1. Loosen the 6 clamping knobs on the 2 option slot covers on the rear of
the BX-UCB and remove the covers and knobs.

2. Insert the Z-board ² into the BX-UCB by aligning the orientation of the
connector inside the BX-UCB and that of the Z-board. Push in the board
along the board rails all the way so that the connector is plugged in
securely.

3. Clamp the Z-board ² using two of the clamping knobs removed above.
Also attach one of the removed covers ³ using the other four clamping
knobs removed above.

}Store the other, removed cover in a safe place.

1 Installing the Halogen Bulb

}Use only the designated bulb 12V100WHAL-L (PHILIPS 7724) or

12V50WHAL-L (LIFE JC).

1. Fully loosen the lamp housing clamping screw @ on top of the lamp
housing cover with the provided Allen screwdriver.

2. Lift the lamp housing cover ² upward to remove it.

3. Turn the lamp socket ³ by 90° in the direction indicated by the arrow.

4. Holding the bulb ƒ with gloves or a piece of gauze, depress the bulb
clamping lever | and insert the bulb pins … fully into the sections † as
far as they will go.
Gently release the bulb clamping lever to the original position to secure
the bulb.

To prevent reduced bulb life or cracking, do not touch the bulb with
bare hands. If fingerprints are accidentally left on the bulb, wipe the
bulb with a soft cloth.

5. Side the lamp housing cover onto the housing base from the above.
Tighten the clamping screw @ while pressing downward on the cover.
(Fig. 40)

Caution for Bulb Replacement During Use or Right After Use

The bulb, lamp socket and areas near these will be extremely hot
during and right after use.
Set the main switch to “ ” (OFF), disconnect the power cord from
the wall outlet, then allow the old bulb and lamp housing to cool
before replacing the bulb with a new of the designated type.

limit.

3. Fully loosen the condenser clamping screw ³ using the Allen screw­driver.

}When attaching the U-SC3 swing-out condenser, align the positioning

pin at the back of the condenser with the groove in the condenser sleeve.

#When attaching a condenser with swing-out top lens, swing out the

top lens out of the way before inserting the condenser.

4. Position the condenser so that the aperture scale or optical device indi­cation plate is located in front. Gently slide the condenser along the
dovetail all the way until it is stopped.

5. Tighten the condenser clamping screw ³ and gently raise the condenser
holder to its highest position.
