1-2 Conformity of the System
Restrictions in Use
1. The standard TV adapters are the U-TV1X-2 and U-TV0.5XC-3.
The U-TV0.25xC, U-TV0.35xC (or a TV adapter with magnification below 0.5X), U-TV0.5XC and GX-TV0.5XC-DP cannot be
used because of optical performance problems.
2. When the DP21 is connected to the rear port of the U-DPT or U-MPH, the peripheral part of the recorded image may be
deteriorated due to the optical performance of the U-DPT or U-MPH.
3. When two or more intermediate attachments are used, the peripheral part of the image may become dark or obscured
depending on the observation tube and objective in use.
4. When a fluorescent lamp illumination or an illumination stand of the SZX/SZX2 series is used, the image may flicker.
5. When a non-Olympus microscope or a commercially available C-mount lens is used, problems due to the optical
adaptability such as shading may be observed. If a commercially available C-mount lens is used, the thread projection
and lens projection from the C-mount body attaching section should be no more than 4.5 mm.
6. When the specimen has a low contrast (near transparent) or high reflectance (mirror status) and the aperture iris dia-
phragm is stopped down near the smallest aperture, spot flare may be noticeable.
7. When the edge of a non-transmitting object is observed under the STM6 transmitted illumination, flare may be noticeable
due to the difference in brightness between the transmitted sections (over-exposure) and non-transmitting section (under-
exposure).
To reduce the flare, set a lower exposure using the exposure adjustment function or setting the exposure manually.
(Details of STM6 combination)
Edge observation using the MM6-OB3X/5X/10X objective in combination with the MM6C-VL/MM6-ETR
8. When the SZX16 is combined, the peripheral brightness may become insufficient with a zoom ratio of no more than 10x.
9. The image of dark specimens under reflected light or in the darkfield (specimens that need exposure of 1/2 sec. or more
at ISO 100 equivalent) cannot be recorded.
10. Specimens with a distribution that is not suitable for center averaged metering require spot metering or exposure adjust-
ment.
11. When electronic zoom is used for magnification display during focusing, the image may become noticeably coarse with
certain samples.
12. The live image frame rate of 15 fps is possible when the exposure time is no more than 1/15 sec.
13. When the scale recording function or measurement function is used, the image capturing time becomes longer than
usual.
14. The trackability of auto white balance control deteriorates when the specimen contains little white area.
15. The measurement results are simply superimposed on the image and no text file or like is created.
16. The DP21 can handle files of the FAT and FAT32 formats only, and it is not compatible with other file formats. When using
a recording medium of an incompatible format, it is required to convert the format into FAT or FAT32 using a PC.
17. It is not possible to use a special USB memory adopting the security or password lock function.
18. To prevent destruction of the recorded image (data), never perform the following action during recording of a still image
or movie;
· turning power OFF;
· disconnecting the AC adapter;
· disconnecting the recording medium such as the USB memory or LAN cable.
Operating Environment
Temperature: 5 to 35°C. Humidity: 20% to 85% (without condensation).
Recommended Monitor Specifications
A monitor with the 800 x 600 or larger full-color display capability (the factory setting is WUXGA 1920 x 1200).
Compliance to the VESA DDC2B standard.
