ABSTRACT:
The invention concerns an apparatus for beam deflection, in particular for scanning microscopy, a light beam being deflectable by a mirror arrangement that is alternatingly rotatable by a rotary drive. The apparatus for beam deflection makes possible maximum variability in terms of frequency range and maximally achievable oscillation frequency, and is thus usable in flexible and versatile fashion. It moreover allows almost any desired angular offset from the zero point position to be established, and is characterized in that the rotary drive comprises two mutually independent drive units which rotate the mirror arrangement, together or mutually independently, about a rotation axis.
