Device for deflecting a beam includes a rotating driving mechanism with two operating devices working jointly but separate from each other to turn an arrangement of mirrors around an axis of rotation.

摘要

A beam of light is deflected by an arrangement (4) of mirrors rotated alternately by a rotating driving mechanism (1). It is possible to adjust almost any offset angle at all to a zero pint position. The rotating driving mechanism has two operating devices (2,3) working jointly but separate from each other to turn the arrangement of mirrors around an axis (5) of rotation.
