ABSTRACT:
An electro-magnetically controllable beam deflection device for use in an optical system for deflecting a radiation beam obtained from a radiation source, in particular for use in video players. The deflection means may for example comprise a pivoting mirror, or an assembly of a plano-concave and a plano-convex lens which with their concave and convex surfaces face each other, and can perform pivoting movements at a small distance from each other. The deflection means is connected to frame by means of an integrated plastic bearing component. The bearing component has a local portion of small cross-section which under the influence of the control forces exerted on the deflection means, is relatively readily deformable. This portion may for example take the form of an integral hinge or of a thin cylindrical portion.
