That's pretty cool. Maybe this would actually be a good use for the failed Lytro cameras. Changing focus after the shot is taken was always a parlor trick with little use in regular photography, but for microscopy it could be game changing. Has anyone tried microscopy with a Lytro Illum? Seems like you can still buy them used.
A lab I used to work at had a light field microscope system. Sorry, though, its existence is pretty much all I know about it since I never personally got to use it.
