Abstract:
A remote control system, adapted to be connected to a SEM (scanning electronic microscope), said SEM having a movable aperture having longitudinal and transverse axes and a manual aperture alignment mechanism for moving said aperture on said longitudinal and transverse axes and having a movable electron gun having a longitudinal axis and a manual electron gun adjusting mechanism for moving said electron gun about said electron gun longitudinal axis, including:a) a remote display and control panel; b) a first motor drive unit adapted to be externally connected to said aperture alignment mechanism for moving said aperture alignment mechanism to cause said aperture to move on said aperture longitudinal and transverse axes; c) a second motor drive unit adapted to be externally connected to said electron gun adjusting mechanism for moving said electron gun adjusting mechanism to cause said electron gun to move about said electron gun longitudinal axis; d) said first and second motor drive units each having forward and reverse drives; e) said first and second motor drive units connected to said remote display and control panel; f) said display control panel having separate displays for said first and second motor drive units; g) said display and control panel having a power ON/OFF switch, a selector control for powering either said first or said second motor drive units when said ON/OFF switch is on, a speed control for said first and second motor drive units, and forward and reverse direction controls for said first and second motor drive units; h) said display control panel separate displays having changeable readout indicia indicating the direction and amount of travel of said aperture during and after alignment and of said gun during and after adjustment during and after actuation of said first and second motor drive units.
