ADJUSTMENT MOUNT FOR RADIAL ADJUSTMENT OF AN OPTICAL UNIT HAVING AN OPTICAL AXIS

The invention relates to an adjustment mount (0) for the radial adjustment of an optical unit having an optical axis, containing a support (1) and an auxiliary mount (2) which is radially adjustable with respect thereto via adjusting devices (3). The adjusting devices (3) each contain a set screw (3.1) of which the ends are arranged in cylindrical elements (3.2, 3.3) which are rotatably mounted in the support (1) and in the auxiliary mount (2). This allows the set screws (3.1) to perform compensating movements during the adjustment, which allows a force-free radial adjustment in one adjustment plane. To fix an adjustment position, the auxiliary mount (2) is held clamped between two cover elements (4) which are fastened to the support (1) and braced together such that, during and after fixing, only moments or forces acting perpendicularly on the adjustment plane are effective. The invention also relates to an apparatus having at least two adjustment mounts (0). The supports (1) of the adjustment mounts (0) can advantageously be different components of a common frame.
