#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.

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.

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.

Check the framing (recording area). (If a live image has been displayed in a magnification other than 1X, return it to 1X.)

(P. 15)

Press the EXPOSE button to photograph and record a picture.

· Check the recording result. (P. 29)

RECORDING FUNCTION SETUPS/OPERATIONS (REC)

5-1 Operations Using the Control Box Buttons (REC)

}After installing the CF card, set the main switch @ to “ ” (ON) and confirm that the POWER indicator LED ² lights up.

(The display shows an image in about 5 seconds after the indicator ² lights up.)

}For the display resolution setting, see page 26.

1. Press the INFO (recording information) button ³ to display or hide the INFO display alternately. To perform setups, it is required to display the INFO display. (Factory setup: INFO display ON.)

2. The displayed information contents are variable depending on the REC AUTO (auto recording), REC MANUAL (manual recording) and PLAY (playback) mode setting. (For the INFO display in each mode, see page 7.)

}Press the MODE button @ to switch the mode between REC AUTO

(auto recording), REC MANUAL (manual recording) and PLAY (playback).

1. Select a record mode, which is either REC AUTO or REC MANUAL.

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

}Provided that the beep tone is set to ON, warning composed of three

TIFF JPEG

}The compression rates are as follows:

SHQ (TIFF): No compression. SHQ (JPEG): 1/2.7. HQ (JPEG): 1/8. SQ (JPEG - Low): 1/2.7. SQ (JPEG - High): 1/8.

}The sensitivity (ISO rating) in recording can be set like a photo

film. The provided ISO values are set by converting the obtained sensitivity into an ISO value of photography films. Three ISO values including 100,200 and 400 are available. A larger value indicates that the camera becomes more suitable for recording darkish specimens or quickly moving objects.

#Although increasing the ISO value makes the camera

suitable for recording darkish specimens under low light, it also results in increasing noise in the picture. Select the appropriate ISO value according to situations.

3 Setting the Sharpness

Factory setup: NORMAL

}The sharpness of picture can be selected from three

options including “NORMAL” , “SOFT ” and “OFF”. “NORMAL” provides sharp contours which is suitable for printing and viewing, while “SOFT” reproduces more natural contours. “OFF” does not correct the sharpness so it is suitable for post-processing of images on a PC.

file are named automatically inside the DP20. The files are named in the range from file Nos. 0001 to 9999 and the folders are named in the range from folder Nos. 100 to 999. The file and folder can be named by one of the two methods including AUTO and RESET. These options can be selected from item FILE MENU in the menu. Note that the maximum number of image files that can be stored on one CF card is 10,000. With TIFF images, the maximum storable number is 5,000.

Folder name File name

Folder No.: 100 - 999 Month (1 - C)

Day (01 - 31)

File No. 0001 - 9999

* In the “Month” expression for the file name, January to September are expressed as “1” to “9”, October as “A”, November

as “B” and December as “C”.

How the folder and file are named in each mode {AUTO

When the CF card is exchanged, the file No. becomes the number continuing the file Nos. which have been recorded on the previously used CF card to avoid overlapping. (Example) When a CF card recorded till Folder No. 100/File No. 0005 is exchanged with another CF card:

When pictures are copied file by file onto a PC, the file Nos. do not overlap even when the pictures were recorded in multiple cards. Note that, however, when 9999 pictures have been recorded, the file No. returns to 0001.

{RESET

When the CF card is exchanged, both the folder No. and file No. are reset. (Example) When a CF card recorded till Folder No. 102/File No. 0005 is exchanged with another CF card recorded till Folder No. 105/File No. 0008:

· When a picture is copied onto a PC, the copied picture has the same folder name as the copy source folder name, thereby making the data management easier.

Actual examples of scale settings

· Assume that the 4X,. 10X and 20X objectives are switched and a 0.5X TV adapter is used. Note that the magnification of eyepieces does not affect the scale setting.

@How to calculate the available photographing magnifications

This is equal to Objective magnification x TV adapter magnification. Therefore, it is 2X with the 4X objective, 5X with the 10X objective or 10X with the 20X objective.

²How to set the photographing magnifications

ON1: Set the magnification with the 4X objective. 0002.00 (which represents 2X) ON2: Set the magnification with the 10X objective. 0005.00 ON3: Set the magnification with the 20X objective. 0010.00

³How to set the registered data number

}Any numbers can be set, but most convenient is to register the objective magnifications.

ON1: Since the objective magnification is 4X 004 (which represents the 4X objective) ON2: Since the objective magnification is 10X 010 ON3: Since the objective magnification is 20X 020

|When performing microscopic observation using the 4X objective, set the registered data number to ON1/004. It

should be set to ON2/010 when the 10X objective is selected.
