An accessory for use with a microscope or other optical system and a camera to record or observe static or moving scenes clearly in focus over a depth of field many times that possible without it, and in some embodiments to allow control of perspective. The axial position of the plane in focus is changed continuously by the changing power of a rotating optical component (1) or set of lenses interposed between the microscope (10) and the scene (7). Illumination is arranged through a synchronously rotating slit (3) so that only the plane instantaneously in focus is illuminated. |
