An optical resonance scanner has a spring-elastic bending element () excitable to effect rotational oscillations about a longitudinal axis (A-A) using a stationary magnet () and a stationary drive coil () that is wound around a pole shoe (). The pole shoe () is magnetically coupled to the magnet () and has two mutually opposite free ends () between which the bending element () is arranged symmetrically so that a magnetic flux can be transferred substantially perpendicularly to the longitudinal axis (A-A). In superimposition of the magnet- and coil-induced magnetic fluxes the magnet () and a first half () of the pole shoe () form a first magnetic circuit (), and the magnet () and a second half () of the pole shoe () form a second magnetic circuit (), which run in opposite senses with respect to one another in a plane perpendicularly to the longitudinal axis (A-A) through a magnetizable section () of the bending element ().
