    Upto five aperture positions can be selected using push buttons, the centre position of the aperture may be adjusted using arrow buttons. Aperture positions are stored in non-volatile memory so that when selecting a new aperture, re-centering is not necessary. Total movement is 10mmx1mm with position reproducability better than 3um. Motorised aperture drives may be supplied for any column with a side entry aperture holder.
    An optional RS-232 interface in incorporated for remote operation. Aperture selection may then be controlled from a microscope computer control program, removing the need for an accessory panel or keypad.
