What predictive focus method settings are available and how are they used?
Prior to uScope Navigator v4.3, the only predictive focus setting was the grid spacing which specified the maximum number of fields between prediction points.
Starting in uScope Navigator v4.3, predictive focus was enhanced as follows:
The step size specifies the number of motor steps to move the objective (0.1375 microns per step). So, 10 steps is 13.75 microns. The step range specifies the range (in motor steps) above and below a mid-point. So, a step range of 100 is equivalent to 201 steps in total (100 motor steps above and 100 motor steps below a mid-point).
