U-FWR Filter Wheel (Fig. 5)
}The U-FWR can be mounted on a BX, BX2, AX, IX or IX2 series microscope
while the projected part of the motor is positioned at the top. If there is no
interference, however, the installation direction can be changed in any
desired way without compromise in performance.
When using two U-FWR filter wheels in two stages (possible except with
the AX series), one of them should be tilted to prevent interference with the
projected part of the motor.
}When a 25 mm filter is used, light amount becomes insufficient in the
peripheral area of field in super widefield observation (FN26.5).
This is barely noticeable with FN22.
Heat Caution
Since the U-FWR is mounted near the lamp housing, its surface be-
comes extremely hot.
You may accidentally touch the U-FWR when operating the collector
lens focusing knob of the lamp housing. So we recommend that you
use the U-CLA optional extension knob.
1. Attach the lamp housing @ on the filter wheel ².
}This is because the clamping screw of the filter wheel cannot be tightened
easily after the filter wheel has been installed on the microscope.
2. Tighten the filter wheel clamping screw ³ using an Allen screwdriver.
3. Attach the filter wheel on the reflected light illuminator.
4. Connect the connection cable | of filter wheel to one of connectors FW1,
2 and 3 on the BX-UCB.
