A filter with a diameter of 45 mm can be placed on the filter mount on
the base. If you need to place multiple filters, please purchase the U-FC
filter cassette.
CAUTION
1
CAUTION
Even when a filter cassette is used, a filter with thickness of no
more than 3 mm can still be placed on the filter mount.
Using the Filter Cassette (Figs. 14 to 17)
Loading Filters into Filter Cassette
} The filter cassette accommodates filters with a diameter of 45 mm and
thickness of 2.7 mm or less.
} The filter cassette has two filter levels on the right side and one on the
left side.
} When the filter cassette is used, the ECO mode cannot be used because
the human sensor is hidden by the filter cassette.
1. Move all filter levers to the OUT position except for the one belonging to
the slot into which the filter is to be inserted.
2. Slide lever @ to the IN position. Make sure that it clicks securely into
place. (Fig. 14)
3. Holding the lever in the position shown in Fig. 14, put the filter into the
cassette by inserting it in the direction indicated by the arrow.
4. Insert the other two filters in the same manner.
2. Align the key 3 on the bottom surface of the filter cassette with the
positioning slot | on the filter mount, then snap the filter cassette into
place from above.
3. Rotate the filter cassette to align its sides with the base. (Fig. 16)
4. Align the clamping screw 2 with the positioning hole 5 on the filter
mount, then tighten the screw to fasten the filter cassette.

Up to three of the above filters can be loaded in the filter cassette. Moving
the levers 6 on the left and right sides of the cassette to the IN position
brings the corresponding filter into the light path.
* When an IF (interference) type filter is used, flare and ghost may be
observed. These phenomena may be reduced by adding ND filter(s) to
the IF filter.
} The LBD filter is not required when the LED lamp is used.
What is LBD filter?
The color of the sun at the noon of a clear day is called the daylight
color, which looks white to human eyes. On the other hand, the
halogen bulb used as the light source of this microscope does not
emit the daylight-color light. so the LBD filter is engaged in the light
path to convert the color of halogen bulb light into daylight. In general,
engaging the LBD filter makes it possible to observe specimens in
natural color tones.

CAUTION
The fine adjustment knob has been attached on the right side
at the factory.
} The fine adjustment knob is designed detachable to prevent interference
with hand during manipulation of the X-and Y-axis knobs.
Usually attach the knob on the opposite side to the X- and Y-axis
knobs.
1. Using the Allen screwdriver, loosen the clamping screw @ and remove
the fine adjustment knob 2.
2. Remove the seal from the fine adjustment knob screw hole on the other
side and attach the knob by reversing the removal procedure.
3. Attach a provided seal on the screw hole | of the removed fine adjustment
knob 3.
} The fine adjustment dial 3 can be operated with your fingertip or finger
surface at the same time as manipulating the X- and Y-axis knobs.
Adjusting the Coarse Adjustment Knob Tension
Adjust the coarse adjustment knob tension using the tension
adjustment ring @.
The coarse adjustment knob tension is preadjusted for easy use. However,
if desired, you can change the tension using the tension adjustment ring
@. Turning the ring in the direction of the arrow increases tension, and
vice versa.
The tension is too low if the stage drops by itself of focus is quickly lost
after adjustment with the fine adjustment knob. In this case, turn the ring
Fig. 22 in the direction of the arrow to increase tension.
(Fig. 21)
(Fig. 22)

Fig. 23
5Pre-focusing Lever
} 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 @ in the direction of the arrow and lock; the upper limit on coarse
adjustment movement is set at the locked position.
After changing a specimen, approximate refocusing is easily accomplis-
hed by rotating the coarse adjustment knob to reach the pre-focused
position. After this, all you have to do is make fine adjustments with the
fine adjustment knob.
} Stage movement with the fine adjustment knob is not locked.
CAUTION
When the pre-focusing lever is locked, a coarse movement stro-
ke is reduced due to the microscope’s mechanism, causing the
stage not to be able to be lowered to the lower limit. To lower
the stage to the lower limit, release the pre-focusing lever.

1Placing the Specimen
} The dimensions of the slide glass should be 26 x 76 mm with thickness of
0.9 to 1.2 mm, and the cover glass should have thickness of 0.17 mm.
} When observing very large specimens, remove the slide holder and place
the specimen directly on the stage.
Microscopy with Double-Slide Holder (Fig. 24)
1. Turn the coarse adjustment knob @ to lower the stage.
2. Open the spring-loaded curved finger 2 on the slide holder and place
one or two specimen slides on the stage from the front.
3. After placing the sides as far as they will go, gently release the curved
finger.
Microscopy with Single-Slide Holder (Fig. 25)
The specimen side can easily be placed by sliding it into the slide holder
from the front.
Examining a whole specimen
Use one of the thin slide holders listed below that cause less interference
with the objectives*.
· U-HRD-4 · U-HLD-4 · U-HLS-4
* The applicable objectives are ones with 40X or less magnification (except
Apo series).
Using an Oil Immersion Condenser
Use the optional U-SVRO (right-hand knob) or USVLO (left-hand knob)
slotted stage which prevents close contact between the specimen and
stage.
} When a biological slide glass specimen is placed on the U-HLDT4/U-
HRDT4 two-slide holder (thick type), the slide holder may interfere with
the objective when the following conditions are combined;
· The objective in use has a short WD (Working Distance);
· The sspecimen being observed is the specimen placed on the rear
side of the side holder, and;
· The stage is in a rotated position.
If the slide holder contacts the objective, set the provided auxiliary slide
holder @ as shown in the figure and observe only the specimen on the
front side of the slide holder.

3Adjusting the X- and Y-Axis Knob Tension
1. Hold the X-axis knob @ and slide up the Y-axis knob 2 up to expose
the adjustment knobs.
2. Turning the X-axis adjustment knob 3 or Y-axis adjustment knob |
clockwise (in the direction of the arrow) increases the tension and
counterclockwise decreases it.
CAUTION
If the tension is adjusted to tight, a creaking sound may be heard
during stage travel, and the stage stopping accuracy may be
imperiled.
} After long hours of use, the stage guide may be deviated and the stage
travel range may be decreased.
However, this is not malfunction and can be corrected easily as described
below.
[Treatment]
Horizontal direction: Hold the specimen holder and move the stage guide
to the left and right so that it hits the stoppers.
Vertical direction: Hold the upper stage and move it to the front and rear
so that it hits the stoppers.
Stage Feed Knob Rubber Caps (Optional)
} When the X- and Y-axis knobs are fitted with the rubber caps, the knobs
can be adjusted without slipping and fine adjustment is possible by
holding the knobs with a very light force. The knob rubber caps also
reduce fatigue after long hours of operation.
The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness
2 mm) knob rubbers are available.
(Fig. 27)
To attach the knob rubbers:
First fit the larger knob rubber to the Y-axis (upper) knob from below it,
then fit the smaller knob rubber to the X-axis (lower) knob from below it.

4Rotating the Stage
1. Slightly loosen the stage clamping screw @.
2. The stage can be rotated both clockwise and counterclockwise by the
stage clamping screw.
CAUTION
A click may be heard and felt during rotation. However, this is
due to the construction of the substage and does not indicate

5Adjusting the Stage Height
} By lowering the position of the substage, the microscope will accommo-
date specimens with maximum height of 35 mm. This is useful when
observing metallurgical specimens and other thick objects.
1. Lower the stage to the lower limit, then remove the stage from the
microscope.
2. Using the Allen screwdriver, loosen the substage bracket clamping screw
@ and remove the substage.
3. Turn the coarse adjustment knob and raise the focusing block 3 to where
the stopper screw 2 on the arm becomes visible.
4. Using the Allen screwdriver, loosen and remove the upper stopper screw

1Adjusting the Diopter
When diopter adjustment rings are provided on both the left and right, it
is possible to adjust the optimum vision for both the left and right eyes as
described below. The diopter adjustment rings may be provided either on
the eyepieces or the observation tube, and there is no problem even when
the rings are not provided on both of them.
The diopter adjustment ensures parfocality from low to high magnifications
and makes it possible to avoid defocusing even when the objective is
switched.
1. Set the diopter adjustment rings on both sides to scale “0”.
2. Engage a high-power objective (40X or so) in the light path, look into
the right eyepiece with your right eye, and rotate the coarse and fine
adjustment knobs to bring the specimen into focus.
} Do not use an oil-immersion objective.
3. Engage a low-power objective (10X or so) in the light path, rotate the right
diopter adjustment ring @ to bring the specimen into focus. Do not touch
the coarse and fine adjustment knobs during the focusing.
4. Looking into the left eyepiece with your left eye, rotate the left diopter
adjustment ring 2 to bring the specimen in focus.
} The above procedure adjusts the diopter with reference to the right eye,
but it is also possible to adjust with reference to the left eye. In this case,
read the above procedure by inverting “right” and “left.”
} If an eyepiece equipped with a diopter adjustment ring is inserted into
the side equipped with another diopter adjustment ring of the observation
tube, perform the above procedure without moving the diopter adjustment
ring of the observation tube from the “0” position.

2Using 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.

3Using the Eyepiece Micrometer Disk
When the WHN10X-H (WHN10X) eyepieces are used, an eyepiece
micrometer disk can be inserted in one of them. When the eyepiece
does not have a diopter adjustment mechanism, however, it is hard to
focus on the micrometer disk if the operator has poor eyesight. Should
that be the case, adjust the focus with eyeglasses on.
Use 24 mm dia. x 1.5 mm thick micrometer disks.
Following Fig. 33, turn the built-in micrometer-mounting frame 2 coun-
terclockwise to remove it from the eyepiece and place a micrometer
disk @.
Screw the micrometer mounting frame back into the eyepiece sleeve.
} Be careful not to touch the lens surface with your finger.
} The micrometer-mounting frame may be tight for certain micrometer disks.
In this case, turn the frame slowly but with a stronger force than usual.

With the U-ETBI/U-TTBI (Fig. 36)
The U-ETBI and U-TTBI are ergonomic observation tubes with normal
field, capable of the adjustments of the positioning angle (0° to 25°) as
well as front-rear positioning (by 45 mm) of the eyepieces. The U-ETBI is
the erect image model and the U-TTBI is the inverted image model, and
both models are of the same size.
CAUTION
The intermediate attachments that can be combined with the
U-TTBI are limited. For details, please contact Olympus.
With the U-TTLBI (Fig. 37)
The U-TTLBI is a Tilting, Telescopic, Lifting binocular tube with the following
adjustment capabilities.
· Eyepiece angle adjustment (0° to 27°)
· Eyepiece up-down position adjustment (45 mm)
· Observation tube front-rear position adjustment (55 mm)
} When adjusting the front-rear position of the observation tube, hold the
base of the observation tube as shown in Fig. 38.
} When storing the microscope, increase the angle of the eyepieces so as
to prevent the eyepieces from dropping.
} To adjust the up-down position of the eyepiece, turn the dial 2.

6Using Eyepieces Incorporating a Micrometer
} When the eyepieces in use incorporate a micrometer, the accuracy of
the left-right focusing adjustment (diopter adjustment) can be improved
further.
1. Looking into the right eyepiece with your right eye, turn the top of the
eyepiece @ so that the micrometer in the field of view looks sharpest
(Fig. 39).
2. Looking into the right eyepiece, rotate the coarse and fine adjustment
knobs to bring the specimen and micrometer (cross lines, etc.) in focus.
3. Looking into the left eyepiece with your left eye, rotate the diopter
adjustment ring 2 to bring the specimen into focus.

5-6 Immersion Objectives
CAUTION
Be sure to use the provided Olympus Immersion oil.
1Using Immersion Objectives
1. Focus on the specimen with objectives in the order of lower-power to
higher-power ones.
2. Before engaging the immersion objective, place a drop of provided
immersion oil 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.
CAUTION
Fig. 40
CAUTION
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 eyepiece 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 repeatedly defocus
and refocus the oil immersion objective.
} 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 immersion oil from the objective front lens by wiping
with gauze slightly moistened with absolute alcohol.
Caution in use of immersion oil
If immersion oil enters your eyes or contacts with your skin, imme-
diately take the following treatment.
Eyes: Rinse with fresh water (for 15 minutes or more).
Skin: Rinse with water and soap.
If the appearance of the eyes or skin is altered or pain persists,
immediately see your doctor.
(Fig. 40)
5-7 Objectives with Correction Collar
} If the thickness scale setting of the objective with collection collar does
not match the cover glass thickness, the objective cannot manifest the full
performance. To prevent this, be sure to perform the following adjustment
when using an objective with collection collar.
Adjustment Procedure
