The focus point of the microscope is generally the pointer tip, while the other pointer end is
the center of the lens system.
The microscope-related trajectory is displayed in blue. The microscope's focal axis and the
field of view are indicated in the 3D display by a line and a circle. If a target has been
planned, the distance from the focus point to the target can be displayed.
Further details on microscope images and how to display them is provided on page 220.
Overlaid Objects
Overlaid objects are always displayed at the focal point. This may lead to misinterpretation
of the position of an overlaid object (relative to the actual object) if a wide field of depth is
used. If the correct position of the overlaid object is critical, use a shallow field of depth.
