Correct assembly and adjustments are very important for the microscope to manifest its
full performance. If you want to assemble the microscope by yourself, see Chapter,
“ASSEMBLY” first.

1. Important
The Motic DSK is a side-by-side dual viewing stereomicroscope system. As it allows two
observers to sit side by side, it is ideal for education and training purposes. Note that
there are few restrictions on the installation location of this attachment.
The orientation of the images observed by the primary observer and the secondary
observer is the same in both the vertical and horizontal directions.
1.1 Getting Ready
1. This manual pertains only to the DSK attachment. Before using this attachment in
conjunction with the SK500/SK700 Stereo microscope and associated options, make
sure that you have carefully read and understood the corresponding manuals, and
that you understand how the various components of the microscopic system are
used together.
2. The DSK attachment is a precision instrument. Handle it with care and avoid
subjecting it to sudden or severe impact.
3. Do not use the attachment anywhere where it may be exposed to direct sunlight,
high temperature and humidity, dust, or vibrations. (For operating environment
conditions, see Section, “SPECIFICATIONS”
4. Before replacing the pointer illumination bulb, be sure to set the main switch to
“(OFF)”, unplug the power supply unit and other cords and wait until the bulb and
its surroundings have fully cooled down.
5. be sure to use only the specified tungsten bulb when replacing the pointer
illumination bulb.
Applicable bulb 6V1OWGE (mfd. by Hosobuchi Electric Lamp)
6. Do not plug the pointer illuminator cord into any unit except the Motic deliverd power
supply unit.

7. Make sure this attachment is installed in a room where there is as little vibration as
possible and that the work surface on which this attachment is installed is sturdy
and level (with inclination within 5°). If vibration is still noticeable, use a anti-vibration
pad.
8. Before placing a specimen which is sensitive to static electricity (such as a
packaged circuit board) on the stage of the large base, place a conductive mat or
similar object on the stage.

1.2 Maintenance and Storage
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.
 The equipment uses plastic resins extensively in its external finish. Do not attempt to
use organic solvents to clean the non-optical components of the microscope. To
clean these components, use a lint-free, soft cloth lightly moistened with a diluted
neutral detergent.
 Never disassemble any part of the microscope as this could result in malfunctions or
reduced performance.
 This equipment should be disposed of by following the rules and regulations of your
national or local government.
1.3 Caution
 If the attachment is used in a manner not specified by this manual, the safety of
the user may be imperiled. In addition, the attachment may also be damaged.
Always operate the equipment as outlined in this instruction manual.

4. Operation
4.1 Focus adjustment
4.1.1Focusing at the primary observer Position
1. Switch on the main switch on the power supply unit to light up the pointer.
2. Look through the primary observer’s eyepiece to see the pointer. If the pointer is not
visible in the field of view, use the pointer control lever D tobring it into the center of
the field.
3. Loosen the lamp socket clamping knob slightly. Then, while looking through the
eyepiece, turn the lamp socket until the pointer is brightest, then tighten the clamping
knob.
4. Turn the right eyepiece diopter adjustment ring until the pointer is in focus.
5. Look through the right eyepiece and focus on the specimen using the coarse and fine
focusing knobs on the microscope body.
6. Turn the left eyepiece diopter adjustment ring until the specimen is in focus.
The pointer and the coarse and fine focus adjustment knobs can be operated only
from the primary observer’s side. They cannot be controlled by the secondary
observer.
4.1.2 Focusing at the secondary observer Position
Turn the left and right eyepiece diopter adjustment rings until the specimen is in focus.
(When the specimen is in focus, the pointer is also brought in focus.)

9
4.2 Using the pointer
4.2.1 Pointer Brightness Adjustment
Looking through the eyepiece, set the pointer brightness by turning the brightness control
knob on the power supply unit.
If the eyepiece incorporates micrometer disks, setting the pointer brightness to ” H “ while
observing a dark specimen may generate a pointer ghost image.
Indication Application
H Used with brightfield of view
M Used with normal brightfield observation
L Used with dark field of view (darkfield observation, etc.)
4.2.2 Pointer Displacement
You can move the pointer to any desired location within the field of view by moving the
pointer control lever on the rear up, down, left or right.
When not using the pointer, use the lever to move it outside the field of view.

10
4.3 Photomicrography cautions
In general, the procedure for taking photographs (including digital camera photographs)
is the same as usual. This section describes special considerations that apply when
taking photographs with the SDK attachment installed.
1. Provided that the primary observer’s position is on the right side, you can take
photographs that include the pointer using a eyepiece adapter.
2. Pointer brightness is set higher than specimen brightness to ensure adequate
contrast. This has the following effects on photographs that are not apparent during
visual observation.
a) Since the pointer is always overexposed when exposure is correct for the
specimen, the pointer color will fade to white in color photographs.
b) When taking a photograph with a photomicrography system with automatic
exposure control, the brightness of the pointer will cause the specimen to be
underexposed. To prevent this, set the photomicrography system’s specimen
distribution compensation dial to the “OVER’ position.
c) Since the effects of the pointer are greater when making long exposures of dark
specimens, first check the exposure time with the pointer illumination turned off.
Then, after turning the pointer illumination back on, make the exposure manually
with the exposure time identified above.
3. Take photographs from the primary observer’s position.
* When taking photographs, be sure to place the reverse incidence prevention cap on
the secondary observer’s eyepieces.
* To avoid reducing stability, do not install the photomicrography system / digital
camera at the secondary observer position.
