Device for preventing the displacement of an optical element

摘要

In a device for preventing the creeping of an optical element, in particular a lens or a mirror, the optical element is connected to a mount via connecting members arranged on the circumference of the optical element. The position of the optical element in an objective (PL) deviates from the vertical axial position. In order to compensate the dead weight at least of the optical element at least one holding element via which the optical element is held on a housing part of the objective (PL) is provided in addition to the connecting members.
