Sliding Nosepiece
The sliding nosepiece can be attached two objectives into the near side socket and the far side socket.
The objectives are changed by sliding the nosepiece to and from.
2.1
Objective Vertical Movement Lever and the Objective Position
You can move the objective upward and downward by
operating the objective vertical movement lever on the
sliding nosepiece from side to side. This operation is
independent of the focus knob operation.
This operation is useful for retracting the objectives to
switch objectives and for dipping the objective into the
water to perform the water immersion.
You can operate the lever only when the objective is
placed in the optical path.
The vertical movable range of the objective is up to 15 mm
above the focal point. With this movable range, you can
observe a specimen in a high petri dish.
The table below shows the relationship between the objective vertical movement lever position and the
objective position.
