Adjust the focus.
Turn the focus knobs of the remote controller to move the
focus mount of the focus unit vertically and focus on the
sample. The figure shows the turning directions of a knob
and the corresponding vertical movements of the focus
mount (zooming body).
• Turning the knob backward: Upward movement
• Turning the knob forward: Downward movement
(See Chapter 7, “7 Focusing on the Sample.”)

Focus operation
Focus speed switching
The focus speed can be switched between coarse,
fine, and extra fine control.
Use the fine/coarse focus switching button on the
remote controller to switch the speed.
Each time the button is pressed, the focus speed is
cyclically switched in the order of coarse, fine, and
extra fine.
When the focus speed is changed, the
corresponding indicator (Coarse/Fine/ExFine)
lights.
• Coarse: 2 to 10 mm/second
• Fine: 0.2 to 5 mm/second
• Extra fine: 0.01 to 0.1 mm/second
Notes on turning the focus knobs
• When using the focus knobs of the remote controller,
do not turn (or twist) the right and left focus knobs in
opposite directions at the same time. Doing so may
cause malfunction.
• When the focus knobs of the focus unit or focus mount
reach their rotational limits for the unit’s vertical
movement, do not forcibly turn it further. Doing so may
cause malfunction.
Do not turn the knobs in the opposite direction!
