Optical compensation
Skip boundary
The boundary of the 3D plot may have weird bends due to the difficulties of determining the right focus plane.
In such cases the 3D may show up better if the boundary is slightly trimmed.
Suggested value is 3-5%
Focus parabola
The boundary of the 3D plot may have weird bends due to the difficulties of determining the right focus plane. This is often due to non-telecentric objective or shift in a stereo microscope.
In such cases the 3D may show up better if the boundary is slightly trimmed away.
Suggested value is 3-5%
Mechanical compensation
When making 3D plots of surfaces with very little height, it is very disturbing if the stage has a slight tilt.
This may be corrected by the X- and Y-tilt compensation.
