Beam Optics

Well focused particle beams are a key factor in the field of electron and ion beam technology. Therefore, D.I.S Germany provides highly developed products of charged particle beam optics, which allow for further customization to fit perfectly into our customers’ facilities.

Electrostatic lenses are ion-optical elements used to guide and focus charged particle beams without changing their kinetic energy. The most prominent representative is an Einzel lens which consists of three cylindrical electrodes. Focusing of the beam is achieved by applying a high voltage to the central electrode. Electrostatic lenses can be used in broad pressure ranges, down to ultra-high vacuum conditions.
