Adjust the interpupillary.
Adjust to match the distance between your right and left
eyes. Look into both eyepieces and move the binocular
part of the tube so that the right and left fields of view
merge into a single circle.
This adjustment is required for each user.
9
Adjust the focus.
Turn the focus knobs (coarse/fine control) on the right and
left of the focus unit 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.")
Notes on turning the focus knobs
• 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 reach their rotational limits for
the unit's vertical movement, do not forcibly turn it
further. Doing so may cause malfunction.
Notes on the torque adjustment
When the torque is too low, the zooming body may slide down due to the various loads it carries, such as its own weight
or the load of the counterbalance spring inside the focus unit. This may result in injury, such as pinching fingers
between the objective and sample, or cause damage to the sample or objective.
