    Abstract: A microanalyser operating by secondary ion emission and comprising a double magnetic-prism for deflecting the ions according to their ''''momentum-to-charge'''' ratio and electrostatic means for filtering the ions according to their ''''energy-tocharge'''' ratio. An element is provided to operate either as an electrostatic mirror allowing the production of images through ion microscopy or as a transmitting and filtering device incorporated in the make-up of a double-focussing mass spectrometer in accordance with the magnetic prism and an electrostatic condenser.
