When either the primary or secondary observation tube is not being
used, be sure to put the provided reverse incidence prevention cap a
on the eyepiece to prevent penetration of reverse incident light during
observation.

In general, the procedure for taking photographs (including digital camera photographs) is the same as usual. This
section describes special considerations that apply when taking photographs with the SZX-SDO2 attachment installed.
1. Provided that the primary observer’s position is on the left side, you can take photographs that include the pointer
using a trinocular observation tube.
When you use a genuine Olympus trinocular observation tube, photo eyepiece and photomicrography
system, the pointer (
)is always focused.
2. Pointer brightness is set higher than specimen brightness to ensure adequate contrast. This has the following
effects on photographs that are not apparent during visual observation.
1) Since the pointer is always overexposed when exposure is correct for the specimen, the pointer color will fade
to white in color photographs.
2) When taking a photograph with a photomicrography system with automatic exposure control, the brightness
of the pointer will cause the specimen to be underexposed. To prevent this, set the photomicrography system’s
specimen distribution compensation dial to the “OVER” position.
3) Since the effects of the pointer are greater when making long exposures of dark specimens, first check the
exposure time with the pointer illumination turned off. Then, after turning the pointer illumination back on, make
the exposure manually with the exposure time identified above.
3. Take photographs from the primary observer’s position.
·
When taking photographs, be sure to place the reverse incidence prevention cap on the secondary
observer’s eyepieces.
·
To avoid reducing stability, do not install the photomicrography system/digital camera at the secondary
observer position.
