Abstract:
An arrangement for generating a plurality of optical axes oriented in a defined manner relative to one another in which the optical axes are defined by the reflection angles of a light bundle at plane mirror surfaces arranged in different ways, comprising:spherical segments having a section face upon which said plane mirror surfaces are arranged; every spherical segment always including a spherical cap and a circle face; an axis of symmetry of the spherical segment extended beyond the circle face being a mirror surface normal; every spherical segment being embedded with its spherical cap in a recess of a base body; said recess having a center axis, which is essentially adapted to a direction of the mirror surface normal required for orientation of the optical axis, and an outside surface, and there are contact points between the spherical cap of the spherical segment and the outside surface of the recess; said contact points constituting an invariable pattern of contact points which is not dependent on the orientation of the mirror surface; and said spherical segments being rigidly fixed in the recesses of the base body, at least at the contact points, by a connection layer, wherein the plane mirror surfaces can be adjusted with the desired degree of accuracy prior to the final fixation of the connection layer corresponding to the optical axes to be aligned.
