Abstract

The invention relates to an optical system consisting of at least two partial systems. The partial systems can be adjusted relative to each other over an adjusting element which they abut over a sliding surface and can be fixed in place by glue. Here the adjusting element has the form of a cylinder and is positioned between the partial systems so that the optical axis of one partial system travels through the adjusting element parallel to the cylinder axis. One of the partial systems possesses sliding surfaces whose forms are matched to the form of the sliding surfaces which lie in the cylinder top surface of the adjusting element. The adhesion spots in the cylinder top surface are spread uniformly along the cylinder circumference.
