Rotation (Easy, Standard, Advanced)
The angle between the X-direction of the scanner and the X* direction of
the measurement (figure
Coordinate systems ).
Imaging Options (Standard, Advanced)
The reference plane for the image can be aligned to the surface of the sam-
ple using the slope parameters (figure
Coordinate systems ).
X-Slope (Standard, Advanced)
A positive value rotates the image plane around the Y-axis in the counter-
clockwise direction.
Y-Slope (Standard, Advanced)
A positive value rotates the image plane around the X-axis in the counter-
clockwise direction.
The centre position of the measured area can be changed by typing its posi-
tion as well as by using the Move tool in the imaging bar. The zero position
is the centre position of the scanner.
Image X-Pos, Y-Pos (Advanced)
The centre position of the measured area.
Overscan (Standard, Advanced)
The amount by which the scan range of each line is made larger than the
measurement range, relative to the image width. Thus edge effects, caused
by the reversal of the scanning motion, are not displayed in the measure-
ment. Disadvantages of using Overscan are that the maximum scan range
is reduced, the tip moves slightly faster over the sample with the same
‘Time/Line’ setting, and the tip may hit large features outside the measured
image. The value of ‘Overscan’ determines how much the scan range is
