combined with the SZX-ZB12 zoom microscope body, DFPLAPO1.2XPF objective and IX-UCLHG/XE collector lens.
#When this equipment is combined with the SZX-ZB9 zoom microscope body, an objective of 0.75X or less
and/or other collector lens than specified above, the brightness and contrast may be degraded.
SAFETY PRECAUTIONS
1. This equipment consists of precision instruments. Handle it with care and avoid subjecting it to sudden or severe impact.
2. The ultrahigh pressure mercury burner used should be the USH102D DC burner (mfd. by Ushio Inc.), that Olympus
supplies.
3. Ensure that the burner is installed and that connection cords are connected properly before operating the unit.
4. Do not open the lamp housing while the lamp is turned on, or for at least 10 minutes after the lamp has been turned off.
Lamp housing parts are extremely hot and will cause burns if touched. (See page 9.)
5. Do not apply excessive force to the stoppers which are provided for some functions. Otherwise the stopper may be
damaged.
6. Do not attempt to open or disassemble the power supply unit because it includes high voltage parts inside.
7. To ensure safety, be sure to ground the power supply unit. Otherwise the intended electrical safety performance cannot be
obtained.
8. Before opening the lamp housing for replacement of the burner or any other internal part, set the main switch to “ ” (OFF),
unplug the lamp housing’s connecting cord plug from the output connector on the power supply unit, and wait for 10
minutes or more, until the lamp housing cools down.
9. Before replacing the mirror unit, be always sure to set the shutter slider of the illuminator tube in the fully pulled-out (light-
excluding) position or set the main switch of the power supply unit to “ ” (OFF).

1Getting Ready
1. This manual pertains only to the coaxial fluorescence attachment. Before using this attachment together with the SZX
microscope and associated options, make sure that you have carefully read and understood their manuals, and under-
stand how the microscopic system should be used together.
2. The coaxial fluorescence attachment is a precision instrument. Handle it with care and avoid subjecting it to sudden or
severe impact.
3. Do not use the equipment where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations. (The
operating environment should be identical to that of the SZX microscope body.)
4. Always use the power cord provided by Olympus. Before plugging the power cord, make sure that the main switch of the
power supply unit is set to “ ” (OFF).
5. To allow heat from the unit to dissipate well, reserve a distance of at least 10 cm between the lamp housing and power
supply unit.
6. The power cord can be used to cut the power supply in case of emergency. To make this possible, the power supply unit
should be installed so that the power input connector (on the rear of the power supply unit) or the power outlet is easily
accessible for unplugging in case of emergency.
2 Maintenance and Storage
1. Clean all glass components by wiping gently with gauze. To remove fingerprints or oil smudges, wipe with gauze slightly
moistened with a mixture of ether (70%) and alcohol (30%) .
Since solvents such as ether and alcohol are highly flammable, they must be handled carefully. Be sure to
keep these chemicals away from open flames or potential sources of electrical sparks –– for example,
electrical equipment that is being switched on or off. Also remember to always use these chemicals only in
a well-ventilated room.
2. If any part of the equipment (other than glass components) gets dirty, wipe it with a clean cloth. If the part is extremely dirty,
do not use organic solvents to clean it; instead, use a soft, lint-free cloth lightly moistened with a diluted neutral detergent.
3. Do not disassemble any part of the equipment. This could result in malfunctions or reduced performance.
4. The burner has a service life period of 200 hours. When the hour counter on the power supply unit indicates 200 hours,
replace the burner with a new one. (See page 7.)

ASSEMBLY
3-1 Assembly Diagram
}For the assembly of the SZX microscope, refer to the separate instruction manual for the SZX microscope.
# Remove dirt and dust from each part before assembly, and assemble the parts carefully by following the numbers
shown in the figure.
# When the SZX-RFA is combined with another intermediate attachment, some part of image may be cut off and the
performance may be degraded. Also note that the SZX-RFA cannot be combined with the SZX-ILLC.
In case the SZX-RFA is combined with another intermediate attachment, always position the intermediate attach-
ment above the SZX-RFA. If the intermediate attachment is located below the SZX-RFA, it cannot exhibit full illumina-
tion performance.
# When the SZX-BS beam splitter is used together with this attachment, it is not possible to attach the SZX-SLR single
lens reflex adapter onto the left side.
The SZX-BS manufactured prior to February 1998 has a light path switch knob that is too long and interferes with the
SZX-RFA. Contact your local Olympus representative for assistance.

OPERATION
# Overall precautions for observation
1. Verify that the power supply voltage and frequency match the requirements indicated on the name plate.
2. Make sure that the power cord and connecting cord are plugged in securely.
3. Engage the shutter if you interrupt observation for a short time.
(Turning the mercury burner on and off (setting the main switch to “ I” (ON) and “ ” (OFF) repeatedly will significantly shorten
the life span of the burner.)
4. The mercury burner radiates UV rays which are dangerous to the human body. Therefore, do not turn on the burner unless
the equipment is properly assembled.
5. Set the shutter slider to the pulled-out (light-excluding) position during transmitted brightfield observation.
6. Do not apply excessive load onto the lamp housing and illuminator tube by placing your hand on them, etc. Otherwise the
equipment may fall down or the alignment of the optics may be altered.
1Turning on the Power Supply Unit
Set the main switch to “ I” (ON). Between 5 and 10 minutes are required for the arc to stabilize after the burner is ignited.
# Some mercury burners may not ignite the first time the power is turned on. If the burner does not ignite, set the main
switch to “ ” (OFF) once, then set the main switch to “ I” (ON) again after 5 to 10 seconds.
# To avoid shortening the life of the burner, do not turn the burner off within 15 minutes of ignition.
# After turning the burner off, it cannot be re-ignited until the mercury vapor cools and condenses to liquid. Wait for
about 10 minutes before restarting the burner.
# Even while the burner is turned on, opening the lamp housing causes the safety interlock function to shut off power
automatically. In this case, set the main switch to “ ” (OFF), and then wait for more than 10 minutes before restarting
the burner. Before opening the lamp housing, wait until it becomes sufficiently cool.
# When resetting the hour counter, be sure to hold down its button until it reads “000.0”.
2Centering the Mercury Burner (Figs. 14 - 16)
1. With the objective attached, turn the coarse and fine adjustment knobs @
to bring the stage plate ² into approximate focus.
The zoom magnification should be set to the lower magnification.
2. Set the mirror unit switch knob ³ to the "GFP" or "GFPA" position.
If these positions are not available due to the current mirror unit combina-
tion, select a desired mirror unit position.
3. Slide the shutter slider | to the “ND25” or “empty” light path.
# If a desired mirror unit position is selected, the brightness may be too
strong, making it difficult to center the mercury burner. So select the
darkest mirror unit among the connected mirror units. Also, the bright-
ness will decrease when the black side of the stage plate (or black
paper) is used.

4. Screw in the burner focusing knob ƒ fully.
5. Using the burner centering knobs …, adjust so that two arc images of the
specimen will be visible as shown in Fig. 16-A .
# During centering with the minimum zoom magnification, the left side
of the illuminated field may be vignetted. However, the illuminated
field in actual use is not affected.
6. Using the collector lens focusing knob † bring either one of the two arc
images into focus. (Fig. 16-B)
7. Using the burner focusing knob ƒ, adjust so that the sizes of two arc
images will be almost identical. (Fig. 16-C)
# At this point, the two arc images may shift. In this case, adjust the
positions of the arc images using the burner centering knobs ….
When it is difficult to determine the sizes of the arc images, adjust by
using the collector lens focusing knob † to bring the arc images into
focus.
8. While turning the collector lens focusing knob † repeatedly, check that
the degree of blurring of one arc image is equal to that of the other arc
image. (That is, when one of two arc image is focused, check that the
other arc image is in focus also.)
If the degree of blurring of one arc image is different from that of the other
arc image (the focusing positions of two arc images do not match each
other), repeat the above steps 6 – 8.
9. After making sure that the degree of blurring of one arc image is equal to
that of the other arc image (the focusing positions of two arc images are
identical), overlay the two arc images using the burner centering knobs …
under in-focus condition.
(Fit section ‡ on the collector lens focusing knob and adjust by turning
knob Š.)

10. After the two arc images are overlaid, they appear as shown in Fig. 16-D.
This completes the burner centering adjustment.
Note that even if the arc images deviate from the center position to some
extent, it will not pose any trouble in observation practice.
11. Before proceeding to observation, adjust the collector lens focusing knob
† so that illumination on the visual field will be uniform.
}When you have difficulties in operating the collector lens focusing knob,
use the optional U-CLA collector lens adjustment handle which is shown
below.
# To avoid serious injury, never open the lamp housing while the burner
is turned on or immediately after it is turned off.
