• Flickering of the displayed image.
• Instability in exposure.
• Hatching patterns in pixel shift recording (4080 x 3072 or 2040 x 1536 pixels).
However, provided that the brightness can be adjusted using the light intensity control knob or ND filters, the above
phenomena may be attenuated by adjusting the brightness so that the exposure time exceeds 1/50 sec.
For details on the microscope models using AC-driven illumination, contact Olympus.
5. Combinations of this product and non-Olympus microscopes have not been evaluated extensively. Non-Olympus
microscopes and commercially available B4-mount (2/3 inch bayonet mount lens) lenses can be used provided that
they match a CCD with a size of no less than 2/3 inch. However, problems due to optical adaptability, such as shad-
ing, may be observed.
6. When the specimen has a low contrast (near transparent) or high reflectance (mirror status) and the aperture iris
diaphragm is stopped down near the smallest aperture, spot flare may be noticeable.
7. When a low-power objective (below 4X) is used, the peripheral part of the field of view may be obscured. In this case,
use an ultralow-magnification condenser (U-ULC-2).
8. When the U-CFU (real time confocal unit) is used, it is required to set the exposure to a longer period than 1/30 sec.
using the manual exposure mode and control the brightness by engaging or disengaging ND filters.
9. When the specimen has large difference in brightness, particularly when the bright part of the specimen comes on
the upper part of the image, red and horizontal flare may be observed. It is noticeable when the AS is being closed.
The flare will get unnoticeable when the AS is being opened, though the flare may not be completely removed.
