Abstract
In a device for the deflection of a light bundle generated by a light source, wherein this device has a nonmechanical deflection device in which the light bundle enters and exits at a different angle determined by a controlling variable, which angle depends on the wavelength of every light component in the light bundle, it is provided that an optically dispersively active system is provided behind the nonmechanical deflection device in the light propagation direction, wherein the angular dispersion of this system is dependent on the angle of the light bundle entering the system, wherein the angular dispersion compensates for the wavelength dependence of the angle of the nonmechanical deflection device determined by the controlling variable.
