Focus Tool
The
Focus
tool controls the position on Z of the
specimen. It controls the internal Z drive of the
microscope and, if available, the additional high
resolution focus which can either be a Z Piezo
focusing device for a single objective or a Z Piezo
insert for the stage.
The
Z-Position
of the specimen stage / nosepiece
is indicated as a numerical value. This value and
with it the focus position can be changed by using
the arrows next to it
.
The
Step Size
, by which the focus moves when
clicking on the arrows, can be set between 0 and
1000 µm.
The Current Z-Position can be
Set
as
Zero
Position
by clicking the
Manually
button.
In addition a focus software joy stick is available to focus with different speeds.
The white joystick
can be dragged over these areas to focus.
The stage / nosepiece can be moved to predefined positions.
Zero
moves the stage / nosepiece to the position which was set as position zero before.
Work
moves the specimen stage / nosepiece to the Work position. This is the position last indicated as
current Z position before the
Load
button was pressed.
Load
lowers the specimen stage / nosepiece to make it easier for you to change the specimen (or
objective).
Use of an optional high resolution focusing device (Piezo objective focus or Z-Piezo stage
insert)
The
Piezo Position
is indicated as a numerical value. This value and with it the focus position can be
changed. A change of this value updates the value of the microscope focus accordingly.
The
Step Size
, by which the Piezo focus moves when clicking on the arrows, can be set between
0.005 µm and 10 µm.
As soon as the focus position of the microscope is changed (via hand wheel or software), the piezo
objective focus is automatically levelled.
•
A click on the
Leveling
button moves the Piezo objective focus or Z-Piezo stage insert into the center
position of its travel range and the focus position of the microscope is reset to compensate for the
leveling. Therefore, the same Z-level remains visible (the current position is not set to zero).
The motor focus of the stand is operated in the same way via the relevant buttons. Moving into the
Work
or
Load
position is always performed via the motor focus and not via the Piezo objective focus.
Please see printed manual CHAPTER 7 ANNEX of the printed manual for further information on
the Piezo objective focus and Z-Piezo stage insert.
