Operation
"Oscillating with Variable Amplitude" operating mode
The deflection range can be parameterized separately for each of the maximum of 8
distance configurations/focal positions. The limitation of the deflection range for fast appli-
cations ensure that the scan line only sweeps areas that contain bar codes during the time
available. At the same time this allows an almost constant scan line density on the object.
