Teltron Deflection E/M Tube. For investigating electron beams in electric and magnetic fields and determining specific charge e/m through compensation of magnetic deflection by electrostatic deflection. Also for estimating the speed of electrons. The integrated plate capacitor allows electron beams to be deflected by using the Helmholtz coils (not supplied). The beam path is visible on the fluorescent grid which is inclined 15 degrees in relation to the beam axis. Equipped with an integrated focusing electrode system.
