Image overlapping on the z-axis; compensates for poor depth of field by merging several individual images in different focal levels. Only dhs offers algorithms for reflected light, transmitted light and scanning electron microscopy.
The upper figure is an animated multi-level image (focus series through the z-axis), below is the final result image as calculated by the software.


Multilevel image sequence = focus series through the Z-axis (sample: hemispherical solder point on a circuit board)
