4 Frame Clamping Plate
}This is the module for clamping the microscope frame onto an
anti-vibration platform. The applicable anti-vibration platforms are
the following four models
· 25 mm pitch and 50 mm pitch anti-vibration platforms.
· 1-inch pitch and 2-inch pitch anti-vibration platforms.
For the assembly procedure, see item
10 on page 65.
}Pressing the option button ² makes it possible to release or close an
external shutter (UNIBLITZ, etc.) To do this, the external shutter be con-
nected to the right side of the frame using a commercially available
BNC cable.
# When the option button is not used, leave the cap attached to it.
4-2 Focusing Block
}Rotating the coarse or fine focus adjustment knob @ toward the front
(in the direction of the arrow) raises the objective and toward the rear
(opposite direction) lowers the objective.
# Always use the rotation tension adjustment ring ² to control the
rotation tension of the coarse adjustment knob.
The tension of the coarse adjustment knob has been pre-adjusted to
optimum tension, but this can be changed as required. Turn the rotation
tension adjustment ring ² in the direction of the arrow to decrease the
knob’s tension and in the opposite direction to increase it.
If the objective lowers by its own weight or the focusing obtained with the
fine adjustment knob is lost soon, the tension is set too low. In this case,
turn the rotation tension adjustment ring in the opposite direction to the
arrow to increase the tension.
