This window displays the current working distance (the focusing position calculated from the lens current).

When a working distance value is selected from the pull-down list, focus point will be set to the specified working distance.

This window can be used for focusing purposes when the Z-axis of the stage is moved or when it is necessary to set the WD accurately for EDX analysis purposes.

By clicking the Up and Down arrows, you can adjust the WD in 0.1mm increments.

(4)Analysis position setting button

This button can be used to set the WD at 10 mm, such as during an EDX analysis. This button sets a WD without the moving the stage itself.
