When scanning large regions of interest using predictive focus, prediction points may not be well-focused and may be blurry.


This problem is caused by the method used to auto-focus prediction points. The initial focus point selected to start the scan is used as the center of the image stack collected for each prediction point. This may prevent accurate focus for some points within the region that are significantly higher or lower than the initial focus point.


Starting in uScope Navigator v4.3 RC44, the center of the focus stack for prediction points is determined from previously captured neighboring prediction points.

If you are already using uScope Navigator v4.3 RC43 or earlier, contact our support department for the latest software release.
