5. USAGE OF MICROSCOPE COMPONENTS
5.1 Coarse and fine focusing
(Fig. 10-1)
●
Focusing is carried out with the coarse and fine focus knobs at the left and right of the microscope
stand.
●
The direction of vertical movement of the stage corresponds to the turning direction of the focus
knobs.
●
One rotation of the fine focus knob moves the stage 0.2mm. The graduation on the fine focus knob
is 2 microns.
●
Never attempt either of the following actions, since doing so will damage the
focusing mechanism:
●
Rotating
the left and right knob while holding the other.
●
Turning the coarse and fine focus knobs further than their limit.

5.2 Coarse focus torque adjustment
(Fig. 10-2)
●
To increase the torque, turn the torque adjustment ring located behind the left-hand coarse focus
knob in the direction indicated by the arrow. To reduce the torque, turn the ring in the direction
opposite to that indicated by the arrow.
