An improvement in a magnetically focused image intensifier increases the usable range of magnification without degradation of image quality while keeping to a minimum the power requirements of the focusing coils. The improvement comprises an arrangement of focusing coils which reverses the direction of the axial magnetic field distribution between the planes of the photocathode and the phosphor screen.
