IMPORTANT
With the U-UVF248A unit, the U-UVF248LB that is the manual type light source box is replaced with the
U-UVF248LBM that is the motorized type light source box. The U-UVF248LBM is capable of motorized
control of the opening/closing of the shutter and the adjustment of the light intensity.
The applicable scope is also changed to the MX61A motorized microscope frame, and additional mod-
ules and the MX2-BSW control software are newly necessary.
The present instruction manual pertains only to the information specific to the motorized operations. For
other information, please refer to the instruction manual for the manual type U-UVF248 unit (packaged
together with the U-UVF248IM).
Precautions on UV Light
1. The motorized shutter monitors the drive status of the MX61A to prevent accidental irradiation of UV light. However, care
is still required against UV leak from the revolving nosepiece and specimen surface.
2. To prevent unexpected irradiation of UV rays, be sure to close the idle objective positions of the revolving nosepiece by
attaching the caps provided with the revolving nosepiece.
3. Leakage of UV light can be prevented effectively by attaching the optional breath shield on the revolving nosepiece of the
MX61A.
4. Do not bend the UV light guide into a radius below 100 mm to prevent it from breaking. The UV light guide should be
inspected periodically to confirm absence of crack that may lead to UV leak.

SAFETY PRECAUTIONS
Safety Symbols
The following symbols are found on the unit. Study the meaning of the symbols and always use the equipment in the
safest possible manner.
l
Explanation
A high voltage (1 kV or more) is present. Be careful against electric shock.
Symbol
Indicates that the surface becomes hot, and should not be touched with bare hands.
Before use, carefully read the instruction manual. Improper handling could result in injury to
the user and/or damage to the equipment.
Indicates that the main switch is ON.
Indicates that the main switch is OFF.
1. This unit is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impacts.
2. The mercury/xenon burner should be the UXM80E (USHIO), which is available through Olympus.
3. Before using the unit, ensure that the burner is mounted and that cords are connected properly.
4. The lamp housing becomes very hot during and right after use. Do not open the lamp housing during these periods.
5. When the hour counter on the power supply indicates 1000 hours, set the main switch to “ ” (OFF), wait for more than
10 minutes and then replace the burner. Unlike a fluorescent lamp, the mercury/xenon burner seals high-pressure gas
inside. If it is used extremely beyond the service life, accumulated distortion of the glass tube could cause the burner to
burst, though this is a very rare case.
6. The power supply contains high-voltage parts inside and should not be disassembled.
7. Always use the power cord provided by Olympus. Before connecting the power cord into the power outlet, ensure that the
main switch of the power supply is set to “ ” (OFF).
8. Be sure to ground the power supply to ensure safety. If it is not grounded/earthed, Olympus can no longer warrant the
electrical safety performance of the equipment.
9. Before opening the lamp housing for replacing the burner, etc., be sure to set the main switch of the power supply to “ ”
(OFF), disconnect the lamp housing output connector on the power supply, and wait for more than 10 minutes after use
to cool down the burner.
10. The top panel of the lamp housing becomes very hot during operation. To prevent a fire hazard, be sure not to block
ventilation of this part. A space of 10 cm or more should also be reserved around the lamp housing to allow ventilation.
11. If a connection cable contacts the lamp housing or is distributed near it, the cable may melt and cause an electric shock.
To prevent this, be sure to distribute the connection cables at an enough distance from the lamp housing.
12. Do not apply an excessive force to any of the stopper mechanisms provided for the functions of the unit. Otherwise, the
stopper mechanism may be destroyed.
13. The power cord is used to shut down the power supply in case of emergency.
The power cord connector (on the rear of the power supply) or the power outlet should be easily accessible for power
cord disconnection in case of emergency.
14. Never insert a metallic object, etc. into a ventilation slot. Otherwise, an electric shock or malfunction may result.
15. To prevent the system from toppling down, do not combine the module if the total height of the microscope system
exceeds 1 meter.
16. The standard service life of the lamp housing is eight (8) years of use or 20,000 hours of total power ON period, whichever
is the shorter period.
For details, see Inspection Sheet on page 13.

PREPARATION
1Centering the Mercury/Xenon Burner (Figs. 1 & 2)
1. Set the main switch “ ” (ON). Between 5 to 10 minutes until the arc
image stabilizes.
2. Remove the cap @ of the centering scope by turning the cap counter-
clockwise.
3. Observing the UV-cut centering scope, adjust the following controls so
that the brightest and most well focused part of the arc image comes on
the center of the cross lines in the centering scope.
· Burner centering knobs ²
· Collector lens focusing knob ³
4. Set the DUV observation mode and perform the final adjustment to make
the image observed on the UV observation monitor brightest.
5. Attach the cap @ in the original position.
}After long hours of use, the electrodes will be consumed and the
centering position be deviated. The centering should therefore be
adjusted periodically.
Be sure to re-adjust centering after replacing the burner.
Fig. 2
}The motorized control of the MX61A and U-UVF248A is executed using the MX2-BSW control software.
For details on the software, refer to the instruction manual provided with it.
CAUTION To prevent accidental UV irradiation due to mistake, it is prohibited to control a system combining
the MX-OPU61A controller or the MX-HS61A with the MX61A.

2Adjusting the Illumination Center (Fig. 3)
}This adjustment consists of aligning the UV light guide with the center of
the MApo100X objective for 248 nm UV observation.
1. Set the MX61A to the “BF” observation mode.
2. Place a specimen with a mirror surface on the stage.
3. Bring the specimen into focus by switching the objectives for visible light
from the lowest to the highest magnifications.
4. Switch the observation mode to the “DUV.”
The MApo100X objective for 248 nm UV light is automatically engaged
in the light path.
5. Set the shutter switch to “Open” to open the shutter.
6. Bring the specimen into focus by observing the monitor for UV observa-
tion. If the observation image is not displayed or abnormally dark, the
illumination center is deviated. In this case, the light guide mount should
be adjusted.
7. Using a Phillips screwdriver, loosen slightly the three clamping screws @
of the UV light guide mount.
8. Insert the provided Allen screwdriver alternatively into the two adjustment
screws ² and turn the screws until the brightest observation image is
obtained.
9. After completing the adjustment, be sure to tighten the three clamping
screws @.
}Hereafter, the illumination center adjustment is not required until the UV
light guide is replaced. However, when a combined microscope is
changed or an AF unit is added, the illumination center needs to be
readjusted.
The UV light guide is a consumable part. It should be replaced when the
image is deteriorated to a degree it cannot be rendered brighter even by
adjusting the illumination center.
