}When performing observation on a desktop, attach the provided rubber feet (x 4) to the front (x 2) and rear (x 2) parts on the
bottom of the base. Note that the rubber feet are not necessary when installing the microscope on an anti-vibration bench.

Attaching the Revolving Arm
(Fig. 49)
1. Loosen the 2 clamping screws
2
of the revolving arm
1
using an Allen
screwdriver and fit the arm into the mount dovetail on the microscope
frame along the direction of arrow from to .
2. Push the revolving arm all the way until it is stopped, then tighten the
clamping screws.
3. Screw in the light shielding tube

Attaching the Revolving Nosepiece
(Fig. 50)
}The attaching procedure is common for the U-SLRE, WI-SRE3 and
WI-SNPXLU2 revolving nosepieces, except that the WI-SNPXLU2
2
should
be inserted so that the round end comes on the front.
In DIC observation using the WI-SRE3 or WI-SNPXLU2
revolving nosepiece, attach the DIC prisms before at-
taching the revolving nosepiece (see page 25).
1. Loosen the revolving nosepiece clamping screw
1
using an Allen screw-
driver, and slide in the revolving nosepiece
2
along the mount dovetail.
2. Push the revolving nosepiece all the way in and tighten the clamping
screw.
WI-SRE3 Only
}When the microscope has been assembled, the confocality adjustment
and centering of the two objectives can be performed.
Adjusting the Confocality of Objective (Figs. 51 & 52)
}To maintain the accurate focusing even after the objective is switched,
the height of the objective with the higher focal point is corrected by
attaching a washer.
Nine washers with three kinds of thickness (10, 30 and 50 µm), three per
kind, are provided with the microscope.
1. Engage the objective on the front side in the light path. Use the coarse/
fine adjustment knobs on the front side to adjust focusing.
}Accurate focus cannot be achieved if the coarse/fine adjustment knobs
on the back side are used.
2. To find the confocality difference, read the scale indication of the fine
adjustment dial
2
(1 scale graduation: 1 µm).
