USING THE CONTROLS

3-1 Base

Turning On the Bulb (Fig. 3)

1

1. Set the main switch @ to “ ” (ON).

2. Turn the light intensity knob ² clockwise in the direction of the arrow
to make the illumination brighter or counterclockwise to make it darker.

The numbers around the knob indicates the reference voltage values.

Fig. 3

Field Iris Diaphragm (Fig. 4)

2

Using the field iris diaphragm ring @, adjust the diameter of the field
iris for objective power to the extent that it just circumscribes the field
of view. When the field iris diaphragm is stopped down to circumscribe
the field of view, it will exclude extraneous light and improve image
contrast within the field of view.

#When using the 100X objective, the field iris diaphragm image will

not be visible within the field of view. Accordingly, stop down the
diaphragm to its smallest diameter.

Fig. 4

Dummy Slider

3

The dummy slider provided with the microscope frame can be used to
accommodate the optional transmitted light analyzer (U-ANT).
By preparing a transmitted light polarizer (U-POT) and polarizing light
condenser (CH3-CDP), simple polarized light observation becomes
possible.
Also refer to the instruction manual of the CX-POL.

3-2 Focusing Block

Fig. 5

Adjusting the Coarse Adjustment Knob Tension (Fig. 5)

1

1. The coarse adjustment knob tension is preadjusted for easy use.
However, if desired, one can change the tension using the tension
adjustment ring @. Applying a large flat-bladed screwdriver to any of
the grooves ² on the circumference of the ring, turning the ring
clockwise (in the direction of the arrow) increases tension, and vice
versa.

2. The tension is too low if the stage drops by itself of focus is quickly lost
after adjustment with the fine adjustment knob ³. In this case, turn the
ring in the direction of the arrow to increase tension.

Pre-focusing Lever (Fig. 6)

2

CX41

Fig. 6

The pre-focusing lever ensures that the objective does not come in
contact with the specimen and simplifies focusing.
After focusing on the specimen with the coarse adjustment knob, turn
this lever @ clockwise (in the direction of the arrow) and lock; the
upper limit on coarse adjustment movement is set at the locked
position.

}Focusing using the fine adjustment knob is not affected by the pre-

focusing dial. Accordingly, after using the coarse adjustment knob to
lower the stage for changing specimens or applying immersion oil
(see section 3-6), refocusing is easily accomplished by rotating the
coarse adjustment to reach the pre-focusing position, then making fine
adjustments with the fine adjustment knob.

#When not required, leave the pre-focusing dial unlocked.

#Releasing the curved finger with great force or suddenly releasing

your grip on the curved finger knob @ while releasing the curved
finger will crack or damage the slide glass. Always place the
specimen with great care.

Observation with Specimen Holder for Single Specimen Slide

1. Turn the coarse adjustment knob ² counterclockwise (in the direction
of the arrow) to lower the stage.

2. Open the spring-loaded curved finger ³ on the specimen holder and
place the specimen slide into the specimen holder from the front.

3. After placing the slide as far as it will go, gently release the curved
finger ³.

Observation with Specimen Holder for Two Specimen Slides

1. Place the first specimen slide as described in steps 1 and 2 above,
then place the second specimen slide so that it contacts the first
specimen slide.

2. Gently release the curved finger ³.

Observation by Placing the Specimen Slide with One Hand

Place the specimen slide at the front of the stage, then slide the
specimen slide on the stage surface to slowly and gradually open the
curved finger in the direction of the arrow. Insert the specimen slide
into the specimen holder until it is fully and properly seated in the
specimen holder.

· Cover Glass
Use cover glasses of 0.17 mm thickness in order to allow the
objectives exhibit their full performances.

· Specimen Slide
Use specimen slides of 0.9 to 1.4 mm thickness. Using thicker
specimen slides may result in inaccurate imaging of the field iris
diaphragm image on the specimen.

Turn the upper knob which is the Y-axis knob @ to move the
specimen in the vertical direction, and turn the lower knob which is the
X-axis knob ² to move it in the horizontal direction.

#Do not use the specimen holder or stage to move the specimen,

for this will damage the rotating mechanisms of the knobs.

#When the stage and specimen holder are stopped by the pre-

focusing dial, the tension of the X-axis/Y-axis knobs increases. In
this case, do not attempt to turn the knobs to move the stage
beyond the stopped position.

· The aperture iris diaphragm determines the numerical aperture of the
illumination system. Matching the numerical aperture @ of the
illumination system with that of the objective provides better image
resolution and contrast, and also 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. of the objective in use is usually recommended. If necessary,
adjust the ratio by removing the eyepieces and looking into the
eyepiece sleeves while adjusting the aperture iris diaphragm knob ²
until the image shown in Fig. 17 is seen. (Fig. 18)

#If the aperture iris diaphragm is set too small, image ghost may be

observed.

Using the numerical aperture scale:

}Align the aperture iris diaphragm knob ² with the NA value @ on the

scale. The scale value should correspond to the NA number engraved
on the objective.
Since the aperture iris diaphragm knob has a certain width, align the
center line engraved on the knob with the scale indication.
When using a 100X objective, turn the aperture iris diaphragm knob ²
all the way to 0.9 on the scale. (Fig. 18)

Fig. 19

Fig. 20

Using Filters (Fig. 19)

}You can place a filter in the light path with either method.

· Insert a filter with diameter of 32.5 mm @ in the condenser accessory
(CH2-FH or CX-AL) attached below the condenser.

· Insert one or more filter with a diameter of 45 mm ² on the light exit
glass on the microscope base.

}For the types of the filters, please consult Olympus or its catalogues.

Using Darkfield Ring CH2-DS (Fig. 20)

Using Low-Power Light Adjustment Objective CX-LA

}The CX-LA is the lens designed for providing the illumination covering

the illumination field of the 2X objective. The CX-LA can be attached
below a specified condenser (see page 23).

#The CX-LA is designed exclusively for use in observation. As the

aperture iris diaphragm cannot be seen and field iris diaphragm
cannot be used when the CX-LA is used, set both iris diaphragms
to the fully open conditions.

}When the CX-LA is attached on one position of the CX-SLC slide

condenser, observations using the 2X objective and using other
objective can be switched with a one-touch operation.

Fig. 22

Using the Immersion Objectives (Fig. 22)

#Be sure to use the provided Olympus immersion oil.

1. Focus on the specimen by switching the objectives fro the lowest
power to highest power.

2. Before engaging the immersion objective in the light path, place a
drop of immersion oil provided with the 100X objective combination
model onto the specimen at the area to be observed.

3. Turn the revolving nosepiece to engage the immersion objective, then
focus using the fine adjustment knob.

#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 eyepieces 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 to move the oil

immersion objective back and forth a few times.

}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.

4. After use, remove oil from the objective front lens by wiping with gauze
slightly moistened with an ether (70%)/alcohol (30%) mixture.

Caution in use of the immersion oil
If immersion oil penetrates in your eye or attaches to your skin,
apply the following treatment immediately.

Eye: Rinse with fresh water (for more than 15 minutes)

Skin: Wash with water and soap.
When the appearance of your eye or skin is altered or pain
continues, immediately consult the doctor.

Total magnification:

The distance from the cover glass surface to the nearest point of the objective.
The N.A. value represents a performance number which can be compared to the relative
aperture (f-number) of a camera lens. The higher N.A., the higher the resolving power.
The ability to differentiate two points, i.e., the minimum distance by which the objects must be
separated in order to be revealed as two separate objects.
The depth in the image through which the focused image will appear uniformly sharp. As the
aperture iris diaphragm is stopped down, the focal depth becomes greater. The greater the N.A. of an
objective, the shorter the focal depth.
A number that represents the diameter in mm of the image of the field diaphragm that is formed by
the lens in front of it.
The actual size of the field of view in millimeters.
Equals the objective magnification multiplied by the eyepiece magnification.
