Best dissecting microscopes for botanical subjects?

I had heard about, though I don't know where to find more information on it, a camera + computer setup where the camera took a series of pictures with gradually changing focus settings, and the pictures were then combined by the computer choosing only the in-focus portions to create the composite.  This would be extremely useful  in creating substantial depth of field for close-ups, and macro photography generally.  If anyone knows anything about this equipment, I'd be very interested.
