#To prevent electric shock and malfunction, never disconnect or connect a connection cable
while the main switch is “ ” (ON).
1. Be sure to set the main switch of the control box to “ ” (OFF) before connecting or disconnecting the connection cables
and power cord.
When connecting a cable equipped with lock screws, tighten them firmly and ensure that the connector will not slip out
before setting the main switch to “ ” (ON).
2. Always use the specified AC adapter only.
Using another AC adapter will prevent the camera system from operating at optimum levels and may also cause it to
malfunction as well as a fire or burns due to abnormal heating.
3. The cords and cables are vulnerable to bend or twist. Do not apply excessive force to them.
Lay the power cord and camera cable so that they do not come in contact with a heat generating module such as the
lamp housing of the microscope.
4. To prevent the microscope from toppling down, avoid using microscope attachments that may make the total height of
the microscope above 1 meter when they are attached.
5. The AC adapter and the bottom of the control box generate heat after long hours of use. To prevent low-temperature
burning of your skin, be careful not to leave your skin in extended contact with those modules.
6. Connect the provided power cord correctly and ensure that the grounding terminal of the power supply and that of the
3-conductor wall outlet are properly connected. If the equipment is not grounded, Olympus can no longer warrant the
electrical safety performance of the equipment.
IMPORTANT
The DP20 microscope digital camera is designed to be connected to a TV adapter mounted on an
Olympus UIS2/UIS type optical microscope for use in quick recording of images.
The DP20 microscope digital camera can manifest the intended optical performance fully when it is
used in combination with an Olympus TV adapter.

Restrictions
1. The standard TV adapter is the U-TV1X-2 or the U-TV0.5XC-3.
The U-TV0.25xC or U-TV0.35xC (TV adapter with a magnification below 0.5X) and the U-TV0.5XC/GX-TV0.5XC-DP cannot
be used because of their optical performances.
2. When the DP20 is mounted on the rear port of the U-DPT or U-MPH, the image in the peripheral area will degrade due to
the optical performances of the port.
3. When using two intermediate attachments by stacking one on the other, the peripheral area may become dark or
obscured depending on the types of the observation tube and objective used.
4. Under fluorescent lamp illumination, the image may flicker.
5. When the DP20 is combined with a non-Olympus microscope or a commercially available C-mount lens, problems due
to optical adaptability such as shading may occur. Also when using a commercially available C-mount lens, make sure
that neither screw protrusion from the C-mount abutting section nor lens protrusion exceeds 4.5 mm.
6. When the aperture iris diaphragm is stopped down near the minimum aperture during observation of a low-contrast
specimen (nearly colorless and transparent) or high-reflectivity specimen (near mirror), spot flare may be noticeable.
7. When edge observation of a non-transparent subject is performed using the STM combination under transmitted light
illumination, flare may be noticeable due to the difference in brightness between the transmitted area (over-exposure) and
opaque area (under-exposure). In this case, the flare can be reduced by reducing the exposure by means of exposure
adjustment or by using manual exposure.
<< SMT6 combination details >>
Edge observation using the combination MM6C-VL + MM6-ETR and MM6-OB3X/5X/10X objective.
8. This system cannot photograph dark specimens in reflected light fluorescence or darkfield observation (a specimen that
required exposure of 1/2 sec. or more when the ISO is equivalent to 100).
9. If the specimen has a distribution unsuitable for center average metering, it is necessary to use spot metering or exposure
adjustment.
10. When image magnification with electronic zooming is used during focusing, the image may become noticeably rough
with certain specimens.
11. The frame rate for live image (15 fps) is possible when the exposure time is no more than 1/15 sec.
12. When the scale photographing function or measurement function is selected, the image capturing time may be longer
than usual.
13. The tracking of the auto white balance function is deteriorated when the specimen has little white region.
14. The measurement function (not including the scale display function) requires a display resolution of 1600 x 1200 with
UXGA or 800 x 600 with SVGA. The measurement of playback picture is possible only with a TIFF image that has been
photographed with the scale display ON. It is not possible with JPEG images.
The measurement results are superimposed on the image display, but not compiled into a file such as a text file.
15. The available Compact Flush (CF) file formats are FAT and FAT32. Other file formats such as NTFS are not compatible.
If the CF card you want to use is in a format other than FAT or FAT32, you need to format the CF card properly on the PC
before use.
16. The recommended recording medium is the Compact Flash (CF card Type I, up to 4 GB) by SanDisk or Lexar. (For the CF
card models we already confirmed operation, see page 11.)
Operating Environment
Temperature: 0° to 35°C (32° to 95°F). Humidity: 20% to 85% (without condensation).
Recommended display specifications
Full-color capable monitor, 800 x 600 or better. (The factory setting is 1600 x 1200.)
Compliance with the VESA DDC2B standard.
1
Conformity of the System
17. The DP20 picture downloading software/USB driver cannot be used in the camera control (including recording).
18. When connecting a PC to the DP20, connect the DP20 control box to the USB2.0 port of the PC directly. If a connection
through a USB hub is used, malfunction may occur.

DP20
CAUTION The control box incorporates a lithium ion coin battery used for data backup. This lithium battery has
a service life of about 6 years.
Because the control box incorporates a lithium ion coin battery (CR1220), be sure to check local
regulations for proper disposal procedures when disposing of it.
1. The camera system uses precision components. Handle it with care and avoid subjecting it to a sudden or severe
impact.
2. Do not use the camera near a source of strong electromagnetic waves. Otherwise, the displayed picture will be disturbed
and malfunction or failure may also result.
3. When mounting the camera head on a tripod, attach it by using the DP-TRAD tripod adapter, which is separately available.
4. Do not use the camera system in areas where it may be subjected to direct sunlight, high temperature and humidity, dust
or vibrations. For the operating environment conditions, see Chapter 9, “SPECIFICATIONS” on page 46.
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. Parts other than the glass components should be cleaned by wiping with a clean cloth. Do not use organic solvents to
remove major stains. Use a soft cloth slightly moistened with a neutral detergent solution.
3. To avoid any degradation in performance, do not attempt to disassembly or modify any part of the system.
4. When not using the camera system, keep it covered with the dust cover provided with the microscope.
If the camera system is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition,
the camera may also be damaged. Always use the equipment as outlined in this instruction manual.

DIGITAL IMAGE PHOTOGRAPHING/RECORDING PROCEDURE
· Perform all necessary optical adjustments on the microscope.
(The camera system can photograph and record microscope observation images under transmitted and reflected
light illumination as well as other observation techniques (except fluorescence microscopy).
· Use the TV adapter to perform the confocal adjustment between the microscope’s eyepieces and the display
image. (Refer to the instruction manual for your TV adapter for details.)
· The factory setting for the white balance control is AUTO, but this may sometimes be inappropriate for microscopic
specimens with small white parts. When photographing a microscopic specimen, it is recommended to use the
one-touch white balance (OTWB) facility.
Insert a CF card.
(P. 11)
Set the main switch of the control box to “ ” (ON).
(P. 13)
Select REC mode REC MANU or REC AUTO (P. 13)
Set the light path selector knob of the microscope to the photographing (TV) light path.
Adjust the brightness of the microscope.
· Engage the LBD filter in the microscope’s light path.
· Set the intensity control to the indicator or the
specified voltage.
Check the focusing and brightness of the specimen (by viewing the display screen).
<< Focusing procedure >>
· The live image can be zoomed from 1X 2X 4X to
facilitate focusing. Focusing is easier at high zoom
magnifications. (P. 15)
· The optimum focusing position can be identified easily
by displaying the focusing indicator on the display.
(P. 23)
· If the brightness is too high, reduce it by using ND filters.
(Note) Brightness control based on the light intensity
voltage adjustment may be affected by variation in
the illumination color temperature.
· Adjust the picture quality, SPOT, AE LOCK and exposure
adjustment as required.
· The brightness and colors of the live images displayed
on the display may differ from actually recorded pictures.

Exposure adjustment in REC AUTO mode
}The exposure in REC AUTO mode can be corrected in the range of ±2
EV in 1/2 EV steps.
When the specimen is darkish, positive correction is effective because
this provides an overexposure effect by extending the exposure time.
When the specimen is too bright, negative correction is effective because
this provides an underexposure effect by reducing the exposure time.
· Press either cross-cursor button ² or ³ to set the exposure
adjustment value. The setting can be confirmed on the following scale
on the INFO display.
(Example) +2/3 EV
