(1) Image backlash adjustment
1) Set the stage on the microscope frame.
Under observation state (with 100X objective),
*1
check image backlash at the lowest knob
torque. If it is over 2 microns, conduct adjustment.
B
(The knob rotation torque is measured by
turning the knob with a sting or some other
suitable item adhered to it, using tension
gauge.)
D
Tension gauge: OT3326
2) When adjusting Y-movement, loosen the two
screws(*1) and turn the Y-knob "A" to bring
backlash within 2 microns. Turn the stopper
ring "B" to come into contact with knob "A",
and fix the stopper ring using the two
AWU2X2SA(*1) screws.
3) When adjusting X-movement, remove the
X-knob "C" after loosing the two AWU3X3SA
screws.
Loosen the screw(*2). Turn the F-ring "D" to
bring image backlash within 2 microns, and fix
the F-ring using the HU1.7X2SA(*2) screw.
At this time, make sure that the final knob
torque at the lowest is within the following
standard for both X and Y.
Knob torque at the lowest:
X: 0.25 -0.35N (25 - 35gf)
Y: 0.39 - 0.59N (40 - 60gf)
