IMPORTANT

The SZX7 stereomicroscope is provided with the ESD (Electro-Static Discharge) protection specifications. It is provided
with electroconductive coating in the external finish to reduce the surface resistance and grounding lead wires in their
standard stand or system to eliminate static electricity from them.

CAUTION To maintain the ESD protection performance, always use the microscope in combination with the

modules described in this manual or options having the ESD protection specifications. Otherwise,
the grounding will not work properly.

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 microscope is accompanied with the risk of

dropping the specimen. Be sure to remove the specimen
before moving this product.

· Hold the bottom of the stand with one hand while holding

base column with the other hand to avoid tilting the micro­scope.

· In case the specimen is damaged by erroneous operation,

promptly take the infection prevention measures.

2. The desktop should be a level surface with an inclination of less than 3°, and the load to the microscope should be less
than 7 kg (when the SZ2-ST standard stand is used).
The microscope may become unstable when certain intermediate attachment and/or photography unit are mounted on
it. Be careful so that the microscope does not topple down.

3. When the microscope is to be disposed of, follow your local industrial waste disposal regulations.
If you have any questions, please contact Olympus.

Getting Ready

1

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, see Chapter 6, “SPECIFICATIONS” on page 14.)

3. Do not turn the zoom adjustment knobs beyond the stopper positions. Otherwise, the internal mechanism may be
damaged.
Do not turn the left and right zoom adjustment knobs in the opposite directions, as this will result in a failure.

4. Only one intermediate attachment having thickness up to 60 mm can be mounted on the microscope. If two intermedi­ate attachments or an intermediate attachment thicker than 60 mm is mounted, the image may be cut a little.
However, the coaxial reflected light illuminator (SZX-ILLC) is not counted in the number of intermediate attachment.

}When using multiple modules, they should be stacked in order of the SZX-ILLC, SZX-AS, SZX-RFA (SZX-RFL), SZX-SDO,

SZX-APT, SZX-BS, SZX-DA, SZX-FAD and SZX-EPA from the bottom to the top.

Maintenance and Storage

2

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.
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 because
they use plastic resin materials extensively. 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.

4. When disposing of the microscope. Check the regulations and rules of your local government and be sure to
observe them.

}This operation is intended to facilitate the rotation of the knobs while

preventing spontaneous drop of the microscope body. It is recommended
to set the knob tension to a slightly higher level than the point where
spontaneous drop occurs.

1. Hold the left and right focus adjustment knobs @ with both hands, fix the
left knob and rotate the right knob. The rotation tension of the knobs
increases or decreases according to the direction in which the right knob
is rotated.

2. If the rotation tension is increased too much, accurate focusing is not
possible and the mechanism may be damaged.

Adjusting the Interpupillary Distance

helicoids.)

2. Place an easy-to-observe specimen on the stage plate.

3. Set the zoom adjustment knob ³ for the lowest magnification and rotate
the focus adjustment knob | to bring the specimen into focus.

4. Set the zoom adjustment knob ³ for the highest magnification and
rotate the focus adjustment knob | to bring the specimen into focus.

5. Set the zoom adjustment knob ³ for the lowest magnification and rotate
the diopter adjustment rings ² of the left and right eyepieces, instead of
the focus adjustment knob, to bring the specimen into focus.

}Set the zoom adjustment knob ³ for the highest magnification again

and check the image focusing. The diopter adjustment is complete if the
image in accurate focus. If not, repeat steps 3 to 5 above.

Eyepieces with eyepiece micrometer disk

1. Look through the eyepiece with eyepiece micrometer disk and rotate its
diopter adjustment ring ² to bring the micrometer scale into focus.

2. Place an easy-to-observe specimen on the stage plate.

3. Set the zoom adjustment knob ³ for low magnification, look through the
eyepiece with eyepiece micrometer disk and rotate the focus adjustment
knob | to bring the specimen into focus.

4. Set the zoom adjustment knob ³ for the highest magnification, look
through the eyepiece with micrometer disk and rotate the focus adjust­ment knob | to bring the specimen into focus.

5. Set the zoom adjustment knob ³ for the lowest magnification and rotate
the diopter adjustment ring of the eyepiece without eyepiece micrometer
disk, instead of the focus adjustment knob, to bring the specimen into
focus.

}Set the zoom adjustment knob ³ for the highest magnification again

and check the image focusing. The diopter adjustment is complete if the

#The eye shades are not provided with ESD protection performance.

When ESD protection is required, do not use 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.

³ with the engraving facing downward, and fix it with the push ring |.

4. Gently screw in the disk-mounting ring ³ incorporating the eyepiece
micrometer disk into the eyepiece. Turn the ring clockwise to attach it
firmly.

#Due to their structures the WHSZ20X-H/30X-H eyepieces apply a

magnification on the focused plane of the eyepiece micrometer disk.
These magnifications are 1.3X with the WHSZ20X-H and 2X with the
WHSZ30X-H. Be sure to compensate for these magnifications when
using the eyepiece micrometer disk in measurements.
Also, insertion of the eyepiece micrometer disk extends the light
path length and deviates the position of the diopter scale. Correct
this deviation by turning the diopter adjustment ring of the eyepiece
toward “+”.

}When the eyepiece micrometer disk is not used, store it by wrapping in a

clean, soft cloth.

Using the Aperture Iris Diaphragm

3

}Adjusting the aperture iris diaphragm makes it possible to improve the contrast of the observation image and increase

the focal depth.
However, the resolution is degraded when the aperture iris diaphragm is stopped down.

· Slide the aperture iris diaphragm lever.
Slide toward the left ¦ to open the aperture iris diaphragm and toward the right to close it. Adjust while observing the
image to confirm the effects on the contrast and focal depth.

#Stopping down the aperture iris diaphragm too much may degrade resolution or cause an insufficiency in the

peripheral brightness. This insufficiency tends to occur particularly at high zoom magnifications.

#When the SZX-ILLC coaxial illuminator is used, stopping down the aperture iris diaphragm to the minimum may

cut off part of image. In this case, open the aperture iris diaphragm to an intermediate position.

9-3 BX Stage Adapter Type 1 SZX-STAD1

Introduction

1

The SZX-STAD1 is an adapter for use in mounting the U-SRG or U-SRP rotary stage on the SZ2-ST standard stand, SZX-ST
standard stand, large stand or SZX illumination stand. The U-SRP is used in combination with the U-FMP mechanical
stage to enable movement in the X- and Y-directions, which is convenient for framing in photomicrography or TV obser­vation. To compensate for the height of the stage adapter, it is recommended to use also the SZ2-ET auxiliary slave when
the SZ2-ST is used or the SZH-P400 auxiliary column (and the SZX-R drop prevention ring also) when the SZX-ST or SZX
illumination stand is used.

To remove the stage plate, loosen the clamping knob @ and push up
the stage plate from below it.

Adjusting the focus adjustment knob tension (Fig. 20)

}This operation is intended to facilitate the rotation of the knobs while

preventing spontaneous drop of the up/down moving stage. It is
recommended to set the knob tension to a slightly higher level than the
point where spontaneous drop occurs.

1. Hold the left and right focus adjustment knobs @ with both hands, fix the
left knob and rotate the right knob. The rotation tension of the knobs
increases or decreases according to the direction in which the right knob
is rotated.

2. If the rotation tension is increased too much, accurate focusing is not
possible and the mechanism may be damaged.
