We have developed several magnetic-coil based beamline elements for focusing and steering electron beams. The focusing coil creates a strong on-axis magnetic field along the propagation axis of the electron beam. This results in transverse focussing of the electron beam, the focal point can be adjusted by changing the current running through the coil. The focussing coil is ideal for focussing an electron beam on the sample/detector. For more information please consult the specification sheet or contact us.
