IMPORTANT

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 and causing infections. 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 microscope may become unstable when certain intermediate attachments and/or photography unit are mounted

on it. Take the measures so that the microscope does not turn over.

2. To prevent the microscope body from turning over, its left-right pivot angle must be limited to 30° as shown in Fig. 1. The tilt of the desktop surface should be no more than 5°.

3. Sufficient care is required during observation with a low-magnification objective, because the objective’s long WD (Working Distance) can displace the microscope body to a higher position. The measures for prevention of turning over are also required when using

Fig. 1

an auxiliary pillar (SZH-P400/P600), because this also makes the microscope body to be displaced to a higher position.

4. To adjust the microscope body height, be sure to hold the microscope body with one hand while loosening the focusing assembly clamping knob @. (Fig. 1) (Use the drop prevention collar (SZX-R) to prevent a hazard from occurring.) Be careful not to pinch your finger during the adjustment.

Page 6

Getting Ready

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, or vibration. (For the operating environment, see Chapter 6, “SPECIFICATIONS” on page 16.)

3. When moving the microscope, remove the specimen in advance. Then, hold the front part of the base with one hand and hold the rear part of the base with the other hand to avoid tilting the microscope. Also remove any module or attachment from the microscope to minimize the weight before moving.

4. Observe the following cautions when operating the coarse focus adjustment knob or the zooming knob.

Fig. 2

Operation

Focusing Coarse/fine focus

Zooming Zooming knob ²

5. Only one intermediate attachment can basically be used, but two attachments may also be used though the peripheral part of the image may be obscured. For the coaxial vertical illuminator (SZX2-ILLC16) and reflected fluorescent light illuminator (SZX2-RFA16), only either can be attached because they must always be attached at the lowest position.

}The SZX2-ILLC16 is not considered to be an attachment. Therefore, the

SZX2-LBS can be mounted above it without any restriction.

Manipulated Controls

(Fig. 3)

Caution

1. If the knob hits the upper or lower limiting mechanism violently or it is rotated after it hits a limiting mechanism, the internal mechanism may be damaged.

2. If the knobs on the left and right are rotated in opposite directions, the internal mechanism will be damaged. (The rotation tension of the coarse focus adjustment knob should be adjusted using the rotation tension adjustment ring ³ on the knob.)

1. If the knob hits the upper or lower limiting mechanism violently or it is rotated after it hits a limiting mechanism, the internal mechanism may be damaged.

2. If the knobs on the left and right are rotated in opposite directions, the internal mechanism will be damaged.

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. Also remember to always use it only in a well-ventilated room.

2. The equipment uses plastic resins extensively in its external finish. Do not attempt to use organic solvents to clean them but simply wipe them using a lint-free, soft cloth. To clean an extremely dirty part, use a soft cloth lightly moistened with a diluted neutral detergent.

3. Never disassemble any part of the microscope as this could result in malfunctions or reduced performance.

4. When not using the microscope, keep it covered with the dust cover provided. If a module containing a source of heat is mounted on the microscope, wait until it has cooled down before covering.

5. This equipment should be disposed of by following the rules and regulations of your national or local government.

1. Check and tighten the connection of each component, especially the observation tube................................................... (Page 20)

2. Check that the angled formed by the microscope body with respect to the base is less than the

turning-over prevention angle. .................................................................................................................................................................................................................................(Page 19)

3. Adjust the tension of the coarse focus adjustment knob. ..................................................................................................................................................(Page 7)

4. Confirm the correct settings.

3-2 Observation Procedure

1. Place a specimen on the stage. (Page 7)

2. Adjust the interpupillary distance. (Page 10)

3. Make diopter adjustment of the eyepieces. (Page 10)

(The adjustment procedure is variable depending on whether the eyepiece micrometer disk is used or not.)

4. Set the zooming knob @ to the lowest zoom magnification and bring the microscope into focus by rotating the coarse focus adjustment knob ².

5. Rotate the zooming knob @ to the desired magnification and precisely focus the microscope on the specimen with the coarse focus adjustment knob ² and fine focus adjustment knob ³ (the fine focus adjustment knob is not provided with the SZX2-FO).

}The contrast of the observed image and the focal depth of the specimen

can be adjusted with the aperture iris diaphragm ring.

USING THE CONTROLS

4-1 Base

1 Using the Stage Plate

In reflected light observation, the stage plate can be placed either the white or black side facing up.

#Win transmitted light observation, use the transparent glass stage

plate (SP-C).

Placing the Specimen

1. Place the specimen on the approximate center of the stage plate. Hold the specimen with the specimen holder as required.

2. Illuminate the specimen with an illuminator selected according to the specimen under observation.

SZX16

4-2 Microscope Body and Focusing Assembly

Adjusting the Tension of the Coarse

Focus Adjustment Knob

Fig. 4

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

preventing the 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. If the knobs are hard to move because of the weight of option modules and/or TV camera mounted on the microscope body, it is recommended to use the focusing assembly for heavy load (SZX2-FOFH).

#The tension of the coarse focus adjustment knob can be adjusted

with the tension adjustment ring @. Do not rotate the knobs on the left and right in opposite directions, for this will damage the internal mechanism.

1. Rotate the tension adjustment ring @ by inserting the Allen screwdriver ³ into the hole ² on the ring periphery. Rotating the ring clockwise increases the tension of the coarse focus adjustment knob, and rotating counterclockwise decreases it.

#If the microscope body falls down by its own weight or the focus

obtained by fine focusing is lost immediately, the tension adjustment may be too light. In this case, rotate the ring clockwise to increase the tension.

#If the tension adjustment is too tight, delicate focusing will be

impossible and the knob may be damaged. Particularly, to prevent damage, never rotate the fine focus adjustment knob quickly while its tension is extremely tight.

(Fig. 4)

Fig. 5

Engaging and Disengaging the Zooming

Knob Click Stop Function

}When the click stop knob is set to ON, the click stop function is engaged

for each magnification indicated with the zooming knob. When the knob is set to OFF, the zoom magnification can be varied continuously and finely near the click groove. The click stop knob has been set to OFF before the microscope is shipped from the factory.

}A click stop is provided for each of the 12 intermediate indication positions

of the zoom microscope body.

1. To engage the click stop function, rotate the click stop ON-OFF screw @ fully clockwise (in the direction of the arrow) using the Allen screwdriver. The zooming knob then stops at every position corresponding to the magnification indicated on the zoom magnification indication ².

2. To disengage the click stop function, rotate the click stop ON-OFF screw @ fully by three turns from the ON position, in the direction opposite to the arrow, using the Allen screwdriver.

#Do not rotate the screw too much, or the cover may be damaged.

(Fig. 5)

Fig. 6

Adjusting the Aperture Iris Diaphragm

}Adjusting the aperture iris diaphragm increases the contrast of the

observed image as well as the depth of focus. However, setting the aperture iris diaphragm too narrowly degrades resolution.

1. Adjust the aperture iris diaphragm ring @ to the left or right. Rotating the ring toward the left (\) opens the aperture; rotating it toward the right ( ) closes it. Adjust while monitoring the observed image to confirm the contrast and focal depth improvement effects.

#Do not close the aperture too much, for this may cause degradation

in resolution and/or lack of ambient light.

2. Use the scale gradations as references for memorizing the ring position.

#When the microscope is combined with the coaxial vertical illuminator

(SZX2-ILLC16), minimizing the aperture may obscure a part of the observed field of view. In this case, open the aperture to an intermediate position.

(Fig. 6)

Zoom Magnification Indication

The body zoom magnification is indicated on the zooming knob on the right side. The total magnification of observation can be calculated with the following formula:

Objective magnification magnification magnification

2X Objective Collection Collar

}The SDFPLAPO2XPFC objective is provided with a correction collar @ for

use in compensating for the aberration caused due to the observation medium such as water and plastic container. When observing a specimen in a liquid or through a petri dish cover, turn the collar to obtain the optimum contrast.

· Correction is possible for aberration corresponding to water depth of about 5 mm.

· The correction effect may be less tangible when the zoom magnification is low or the aperture iris diaphragm is stopped down.

}When using the SZX2-2RE16 revolving nosepiece, hold the objective

during rotation of the ring so that the revolving nosepiece is not deviated the click position.

Adjusting the Interpupillary Distance

#Be sure to hold the binocular assembly @ with both hands to make

this adjustment. To prevent damaging the mechanism, do not apply an excessive force beyond the stop position.

While looking through the eyepieces, hold the left and right of the binocular assembly @ and adjust the eyepieces by opening or closing them for binocular vision until the left and right fields of view coincide completely.

Adjusting the Diopter

(Zoom Parfocal Adjustment)

}Ensure that the eyepiece clamping knob @ is tightened before starting

the adjustment. Adjusting the diopter specific to the two eyes of each observer allows the parfocality to be ensured across zoom magnifications.

When Not Using the Eyepiece Micrometer Disk

1. Look into the right eyepiece and rotate its diopter adjustment ring ² so that the peripheral part of the visual field looks sharply.

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

3. Rotate the zooming knob ³ to a low magnification and, looking only into the right eyepiece, focus the specimen using the coarse and fine focus adjustment knobs.

4. Rotate the zooming knob ³ to the highest magnification and, looking only into the right eyepiece, focus the specimen using the coarse and fine focus adjustment knobs.

5. Rotate the zooming knob ³ to the lowest magnification, look only into the left eyepiece, and focus the specimen by rotating the left diopter adjustment ring | instead of the coarse and fine focus adjustment knobs.

(Fig. 10)

(Fig. 9)

When Using the Eyepiece Micrometer Disk

1. Look into the right eyepiece that includes the eyepiece micrometer disk, and focus the micrometer disk by rotating the diopter adjustment ring ².

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

3. Rotate the zooming knob ³ to the highest magnification and, looking only into the right eyepiece, focus the specimen using the coarse and fine focus adjustment knobs. Ensure that both the eyepiece micrometer disk and specimen are focused accurately.

4. Rotate the zooming knob ³ to the lowest magnification, , look only into the left eyepiece, and focus the specimen by rotating the left diopter adjustment ring | instead of the coarse and fine focus adjustment knobs.

}Note (or memorize) the diopter readings of the left and right eyepiece

scales so that they can be duplicated quickly in the next observation.

Using the Eye Shades

When Wearing Eyeglasses

Use with eye shades in their normal folded-down position. (This will prevent eyeglasses from being scratched by the eyepiece.)

When Not Wearing Eyeglasses

Extend the folded eyeshades in the direction of the arrow. This makes observation easier by preventing the inverse incidence of light from between the eyepiece and your eyes.

Using the Eyepiece Micrometer Disk

}A variety of eyepiece micrometer disks can be inserted into the WHN10X-

H, WHSZ15X-H and WHSZ20X-H eyepieces.

1. Unscrew the ring @ by turning it counterclockwise to remove it from the bottom of the eyepiece.

2. Clean the eyepiece micrometer disk ² ( 24 mm, thickness 1.5 mm) to remove dust and dirt, then place the disk into the ring @ so that the side with reticule faces downward.

3. Attach the ring @ with the eyepiece micrometer disk ² by gently screwing it onto the eyepiece.

#The WHSZ20X-H eyepiece is designed to apply a magnification to

the focusing plane of the micrometer disk. As the magnification coefficient is 1.35, be sure to perform magnification compensation when using this eyepiece in measurement. When the micrometer disk is engaged in their light path, the light path length will extend and the diopter scale may deviate toward the + direction from the normal indication. However, this does not pose any problem in actual observation.

}When the eyepiece micrometer disk is not used, wrap it in a clean sheet

of soft paper before storage.

Installing the Pillar

1. Using the Allen wrench provided with the base, loosen the two clamping screws @ on the pillar support sleeve completely.

2. Hold the pillar ² so that the Allen screwdriver storage hole comes cap at the top, and insert the pillar into the pillar support sleeve until it reaches the bottom.

3. Using the provided Allen wrench, tighten the two clamping screws @ securely.

Reserve Screw Holes

Two screw holes ³ (6 mm) are provided for use in mounting a manipulator, etc.

Mounting the Focusing Assembly

1. First loosen the focusing assembly clamping knob @ completely and, while holding the focusing assembly with both hands, insert the pillar ³ into the mounting hole ² from below. (Fig. 17)

#Insert slowly. Do not apply excessive force.

(Fig. 16)

(Figs. 17 & 18)

30°or less

Fig. 18

2. Lower the focusing assembly until it stops, then tighten the focusing assembly clamping knob @. (Fig. 17)

To prevent the microscope from turning over, the focusing assembly must be installed on the same side as the stage plate in the stand, as shown in the illustration marked “\” in Fig. 18, and its pivot angle must be limited to 30°. If the focusing assembly is placed on the wrong side, the microscope will turn over.

# If the clamping knob @ is tightened while the pillar ³ is not completely

inserted into the mounting hole ², the plate spring supporting the pillar will deform and the pillar will not be able to penetrate into the hole. (Fig. 17)

Page 24

Fig. 19

Mounting the Microscope Body

1. Remove the cap @ on the focusing assembly by inserting a thin object into the notch.

2. Using the provided Allen wrench, loosen the dovetail mount clamping screw inside the cap on the focusing assembly by rotating it by 2 or 3 turns (counterclockwise).

3. Gently insert the dovetail mount ³ on the rear of the microscope body into the dovetail mounting port ² on the focusing assembly.

#Do not insert the mount at an angle or with excessive force, for this

may cause malfunctions.

4. When the microscope body has been inserted until it stops, tighten the clamping screw using the Allen wrench.

5. Place the cap @ in the original position.

(Fig. 19)

Fig. 20

Fig. 21

Mounting the Objective

#Since the objective is heavy, take the following measures to prepare

for an accident in case it is dropped.

· Attach the cap to the objective tip.

· Place the cap of the objective mount thread or a notebook, etc. on the

stand to absorb the shock even when the objective drops. While holding the tip of the objective ², mount it on the objective mount thread @ by rotating the objective in the direction of the arrow.

Mounting the Observation Tube

1. Using the Allen screwdriver, loosen the observation tube clamping screw @ completely.

2. Aligning the positioning pin ³ of the microscope body to the positioning groove ² on the observation tube, insert the dovetail mount | at the bottom of the observation tube into the mounting port ƒ on the microscope body.

3. Using the Allen screwdriver, tighten the observation tube clamping screw @.

#The observation tube can be mounted 180° from the above position,

but this positioning makes observation difficult and is not recommended. When the auxiliary pillar is used, this positioning is impossible because the eyepiece gets in the way.

(Fig. 20)

Mounting the Eyepiece

}When using the micrometer eyepiece disk, insert it in the right eyepiece.

(It may be inserted in the left eyepiece but the description in this manual assumes that it is inserted in the right eyepiece.)

1. Remove the eyepiece dust caps @ and loosen the eyepiece clamping screws ² completely.

2. Gently insert the eyepieces of the same magnification ³ into the left and right eyepiece sleeves all the way until they stop.

3. Tighten both eyepiece clamping screws ².

Mounting (Removing) the Stage Plate

Place the stage plate into the mounting hole on the base. To remove, press the stage plate at the edge nearest to the pillar with your fingertip. The opposite end will rise from the base so the stage plate can be picked up easily.

OPERATION OF OTHER MODULES

9-1 Drop Prevention Collar SZX-R and Auxiliary Pillar SZH-P400/SZH-P600

}The auxiliary pillar is to be used when observing a large specimen or when it is required to move the microscope body

upward for using a low-magnification objective with long WD.

}The drop prevention collar prevents the zoom microscope body from dropping when installed at a high position using

the auxiliary pillar and the clamping knob on the focusing assembly is loosened carelessly. This helps to avoid accidental damage to the specimen or objective.

#The static load resistance of the SZX-R is 7 kg at maximum.

Assembly

1. Mounting the auxiliary pillar

· Remove the pillar from the standard base and replace the pillar with the SZH-P400 or SZH-P600 auxiliary pillar (see page 19 for the mounting procedure).

2. Mounting the drop prevention collar

· Fit the drop prevention collar @ onto the auxiliary pillar ².

}Position the oblique illumination unit* mounting groove ³ on the front

@ ²

Fig. 26

Operation

When moving the microscope body around the pillar, never loosen both the focusing assembly clamping knob and drop prevention collar simultaneously.

To Move the Microscope Body Upward

1. Loosen the clamping knob of the focusing assembly to be moved upward.

2. At the desired height, tighten the focusing assembly clamping knob securely.

3. Loosen the drop prevention collar clamping knob, press the drop prevention collar tightly against the lower end of the focusing assembly, and tighten the clamping knob securely.

side of the drop prevention collar @ and tighten the clamping knob |.

*The LSGA oblique illumination unit and SZX-LGH1 light guide can be

mounted.

#When the specimen height is low or an objective with a short working

distance is used, the drop prevention collar @ does not have to be mounted if you move the microscope body downward. However, this reduces safety that is assured by using the SZX-R drop prevention collar @, so be always sure to hold the focusing assembly firmly when loosening the focusing assembly clamping knob.

(Fig. 26)

To Move the Microscope Body Downward

First loosen the drop prevention collar, move the microscope body downward, and then move the focusing assembly.

#For the drop prevention collar to exhibit its full effect, clamp the focusing assembly and drop prevention collar in

close contact between each other, without leaving any space.

#Two screw holes are provided at each position with an interval

of 5 mm. When not using the SZX2-RFA16 reflected fluorescent light illuminator, use the screw holes closer to the front.

#As the screw holes may be hidden behind the objective mounts |,

clamp the nosepiece mount while rotating it. (Fig. 28)

5. Install the focusing assembly on the pillar, and install the observation tube in the original position.

6. Attach two objectives onto their respective objective mounts | by screwing.

(Fig. 28)

Operation

Fig. 29

(Fig. 29)

Hold the objective and gently rotate it until a click position on the front, where the objective to be used is engaged in the light path.

Operation for Optical Axis Aligned Photomicrography

}Align the center of objective and that of the illumination light path with

the photo light path (the right line) to enable photomicrography with high contrast.

1. Rotate the desired objective @ clockwise (15°) till the click position for the photo light path. (Fig. 30)

SZX16

2. Return the microscope body to the illumination light path by loosening the focusing module clamping knob ², rotating the microscope body gently in the direction of the arrow, aligning visually the objective with the illumination light path and tightening the clamping knob ² again.

(Fig. 31)

Now the setting of the photo light path is complete.

}If you want to use the right light path, see below.

<< Using the left light path for photomicrography >>

}When the SZX2-LBS beam splitter is used, the left light path can be used

as the photo light path of optical axis aligned photomicrography.

1. Rotate the desired objective @ counterclockwise (15°) till the click position

2. Return the microscope frame to the illumination light path by loosening the focusing assembly clamping knob, aligning visually the objective with the illumination light path and tightening the clamping knob again.

Color temperature setting when using the SZX2-ILLB2 illumination base

}When using the SZX2-ILLB2 in optical axis aligned photomicrography,

perform the following setting to compensate for the color temperature deviation of about 20 mired.

1. Engage the LBD filter, which is built into the bottom section of the SZX2ILLB2, in the light path.

2. Set the brightness control knob of the SZX2-ILLB2 to the maximum brightness position.

}After this setting, the brightness should be adjusted using built-in ND

filters.

Caution

#When transporting the microscope, do not hold it by the revolving nosepiece. #The parfocal property when the objective is switched is not completely guaranteed. #The SZ2-FO variable-height stage cannot be used when the revolving nosepiece is used (because the objective

will come in the way).

#The SZX2-FO focusing assembly cannot be combined with this microscope.

9-3 BX Stage Adapter Type 1 SZX-STAD1

}This adapter is for installation of a U-SRG or U-SRP rotary stage on the SZX2 standard base or a SZX2/SZX series

illumination base. When the U-SRP rotary stage is used together with the U-FMP mechanical stage, X-Y directional movement becomes possible, which is convenient for framing during photomicrography. To cover the height of the stage adapter (about 41 mm), we recommend combination with the SZH-P400 auxiliary pillar (together with the SZX-R drop prevention collar).

Mountable Bases, Restrictions

Base Applicable Objectives Restrictions

Standard base SZX2-ST/SZX-ST

· Transmitted illumination base SZX2-ILLK/SZX-ILLK

· Advanced illumination base SZX2-ILLB/SZX-ILLB2

· Brightfield/darkfield transmitted illumination base SZX2-ILLD/SZX-ILLD2

0.5X to 2X None

The same restrictions apply regardless of whether the stage adapter is used or not. (Refer to the instruction manual for the SZX2/SZX illumination base.) Note that the field illuminated by the transmitted light is limited depending on the diameter of the opening of the stage plate in use.

#Darkfield observation is not possible using the SZX2-ILLD or SZX-ILLD2. #The illumination intensity may be reduced when a frosted filter is used.

9-4 BX Stage Adapter Type 2 SZX-STAD2

}This adapter is for installing the U-SIC4R2/SIC4L2 large stage* on the SZX2-STL/SZX-STL large stand**. When this stage

adapter is used, the SZH-P400 auxiliary pillar should be used to cover the height of the stage adapter (about 125 mm). In addition, when a low-magnification objective with a long working distance (SDFPLFL0.3X) is used, the SZH-P600 auxiliary pillar should be used (always together with the drop prevention collar).

* The U-SVL or S-SVR BS stage for the BX series microscopes can also be mounted but the operability deteriorates. The

U-SVLB and U-SVRB cannot be used due to their long stage knobs.

**A SZX2/SZX series illumination base can also be mounted, but its built-in transmitted illumination cannot be used.

External light source

1. Illuminate the specimen with an external light source (LSD illuminator, light guide illuminator, etc.). Light the external light source as shown in the figure on the left and irradiate the mirror assembly.

2. Eliminate irregularities in illumination.

1) Align the microscope body center with the center of the SZX-STAD2

adapter.

2) Set the zooming knob on the microscope body to the minimum

magnification and focus the stage top surface.

3) While observing through the eyepiece, rotate the mirror knob to adjust

the mirror angle so that the entire field of view is illuminated uniformly.

}When observing using an oblique illuminator, remove the frosted filter

and, while observing through the eyepiece, tilt the mirror gradually until optimum contrast can be obtained.

9-5 Stage Adapter Type 1 SZH-STAD1

This adapter has the same function as the SZX-STAD1 BX stage adapter type 1, but the usable stages with this adapter are the BH2-SH horizontal knob stage and the BH2-SRG rotary stage. The assembly and the SZXPO polarizer installation procedures for this adapter are identical to those for the SZX-STAD1. Refer to the SZX-STAD1 description for related information (page 27).
