4. Combinations of this product and non-Olympus microscopes have not been evaluated extensively.

Non-Olympus microscopes and commercially available C-mount lenses can be used provided that

they match a CCD with a size of no less than 2/3 inch and the lens projection length from the C-mount

body attaching section is no more than 6 mm. However, problems due to optical adaptability, such as

shading, may be observed.

5. When the specimen has a low contrast (near transparent) or high reflectance (mirror status) and the

aperture iris diaphragm is stopped near the smallest aperture, spot flare may be noticeable.

6. There are some cases that red flare appears in the image of specimen which has very big differences

in luminance, and the strong luminance portion is located in the image. This results from the peripheral

surface reflection of the CCD. This flare can be minimized by adjusting the exposure for strong

luminance portion to appropriate level, or by opening the AS.

7. When the edge of a non-transmitting object is observed by transmitted illumination under the STM6

in combination with the MM6-OB3X/5X/10X objective and the MM6C-VL/MM6-ETR, flare may be

noticeable due to the difference in brightness between the transmitted sections (over-exposure) and

non-transmitting section (underexposure).

To reduce the flare, set a lower exposure using the exposure adjustment function or setting the exposure

manually.

8. 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.

9. Specimens with a distribution that is not suitable for center averaged metering require spot metering or

exposure adjustment.

10. When electronic zoom is used for magnification display during focusing, the image may become

noticeably coarse with certain samples.
