Nikon ECLIPSE Si Instructions Manual page 102

Installing the eyepiece tube
Insert the eyepiece tube into the circular dovetail mount
while tilting it so that the eyepiece tube fits into it properly.
Securely tighten the fixing screw for the eyepiece tube while
supporting the eyepiece tube by hand.
Fit the stopper screw for the eyepiece tube, and tighten the
screw by using the supplied hexagonal wrench.
Purpose of the stopper screw for the eyepiece tube
The stopper screw for the eyepiece tube is for preventing
the eyepiece tube from falling when the fixing screw for
the eyepiece tube is loosened. The eyepiece tube cannot
be fastened with only the stopper screw for the eyepiece
tube.
When screws are attached
If you purchase the microscope without the eyepiece tube,
the fixing screw and stopping screw for the eyepiece tube
are fitted into the screw holes and taped to prevent them
from falling out. When installing the eyepiece tube, peel off
the tape and remove the two attached screws, and then
follow the procedure described in "Installing the eyepiece
tube."
When using an eye-level riser
You can raise the eye point by 25 mm by attaching an
eye-level riser between the microscope main body and the
eyepiece tube.
While tilting the eye-level riser, fit it into the microscope's
circular dovetail mount. Fasten the eye-level riser by using
your fingers to tighten the fixing screw for the eyepiece
tube. Then, tighten the stopper screw for the eyepiece
tube by using the supplied hexagonal wrench.
Attach the eyepiece tube to the round dovetail mount on
the upper surface of the eye-level riser. Perform the
attachment correctly according to the aforementioned
procedure.
(3) Attaching the camera mount
The camera mount (C mount) is attached to the camera port
of the trinocular eyepiece tube.
Loosen the knurled screw on the camera port and remove
the cap and C mount. Photomicrography becomes available
after attaching the C mount to the camera, and then
attaching it to the camera port.
The optical path of the trinocular eyepiece tube is fixed at
the ratio: binoculars : camera port = 50 : 50.
For details about photomicrography, refer to the instruction
manual of the camera.
Camera mount cap
Do not lose the cap.
When you do not attach the camera, make sure that the
cap is placed on the camera port.
