Abstract

A device for two-dimensionally scanning beam deflection of a light beam has spectrally tunable light source that emits a light beam having a time-varying wavelength. The device further comprises a first optical component that produces a first beam deflection. The first beam deflection causes the light beam to be deflected wavelength-dependently in a first direction. A second optical component produces a second beam deflection which causes the light beam to be deflected in a second direction different to the first direction. The second optical component comprises a prism pair comprising two prisms that are rotatably arranged successively in a beam path of the light beam. The two prisms are configured to perform continuous counter-rotational movements.
