7 Attaching the Observation Tube (Figs. 96 to 99)
U-BI90CT, U-BI90 or U-TBI90 Binocular Tube
(U-MO Monocular Tube)
1. Using the Allen screwdriver, loosen the observation tube clamping screw
@ on the observation tube mount. (Fig. 96)
2. Attach the circular dovetail mount of the observation tube into the
observation tube mount, placing the observation tube so that the
interpupillary distance scale numbers ² are seen right side up. Then
tighten the clamping screw to clamp the observation tube.
}Normally, the distance from the surface of the desk to the eye point is
approximately 430 mm. If it is desirable to lower the eye point position, the
observation tube (provided it is other than the U-TBI90) may be detached,
turned 180° and then attached on the observation tube mount again. This
lowers the eye point height by approximately 30 mm. (Fig. 97)
U-TR30H-2 Tube (Figs. 98 & 99)
}First mount the IX-ATU intermediate tube.
1. Using the Allen screwdriver, loosen the observation tube clamping screw
@ on the observation tube mount. (Fig. 98)
2. Insert the circular dovetail mount of the intermediate tube into the
observation mount so that its upper surface is flush with the microscope
frame. Tighten the observation tube clamping screw @ to clamp the
intermediate tube.
3. Using the Allen screwdriver, loosen the observation tube clamping screw
² on the intermediate tube’s observation tube mount. (Fig. 99)
4. Insert the circular dovetail mount of the observation tube into the
intermediate tube’s observation tube mount so that the binocular
eyepiece sleeves face toward the front. Then tighten the observation
tube clamping screw ² firmly. (Fig. 99)
