Device for the controlled deflection of a focussed light beam

摘要

The invention relates to a device for the controlled deflection of a focussed light beam in two dimensions, in particular for controlling a luminous point for marking specific locations on a display section, e.g. on a printed circuit board or the like which is to be fitted, through the use of a deflecting system in the light beam. According to the invention, the deflecting system has a mirror (1) which is arranged obliquely relative to the light beam and is mounted or supported on its rear at three points (a, b, c) under pretensioning (2). At least two bearing points are arranged in an adjustable manner in a direction perpendicular to the surface of the mirror or its rear.
