Fixing Distance (FD)
Marking Area (MA)
Working Distance is defined as the distance between the center of the
marking area (defined in the focal plane) and the closest mechanical edge
of the F-Theta scan lens.
The Working Distance tolerance is defined as the ± 2-Sigma value of devia-
tion from Working Distance mean value of the estimated Gaussian model.
Refer to the following figure.
Fixing Distance is defined as the distance between the base of the scan
head and the marking area.
The Fixing Distance tolerance is defined as the ± 2-Sigma value of devia-
tion from Fixing Distance mean value of the estimated Gaussian model.
Refer to the following figure.
For products equipped with 160S, 254S, 160L and 100L F-Theta scan
lenses the focus position, defined at the point where the focus beam over-
laps with the aiming beam, is preset at factory.
