1. An Optical device for speckle pattern reduction, comprising:
a diffusor configured to diffuse a light beam passing through said diffuser to reduce a speckle pattern,
a support frame configured to support the diffusor,
a spring structure connected to the support frame, wherein the spring structure comprises a frame to which the diffusor is connected, wherein the frame is moveable with respect to the support frame, and wherein the spring structure comprises a first holding member that is connected via a first spring element to the frame, and
an actuator configured to move the frame with respect to the support frame by means of a Lorentz force.
