Our EDF system allows the user to combine a stack of multi-level focal planes into a single in-focus image. It incorporates our simple to use software/hardware interface. Users can simply focus on the top and bottom of the focal planes and the software does the rest. Delta Z is displayed on the screen as is the fully in-focus image of the data stack. Microscope configuration is based upon the users samples. Macroscopes and Microscopes are both available for this technique.
