摘要

Mounting devices with a receptacle along an optical axis for an optical component in a cylindrical holder and with setting elements for adjusting the holder along the axis or along and about the axis are provided. The number of setting elements for adjustment of an optical component is reduced and the setting elements are formed and arranged in a space-saving manner and simplify an adjusting operation. In one embodiment the receptacle (13) and the holder (17) engage one another via corresponding thread segments (14, 19) such that a rotational movement of the holder (13) by engaging an adjusting tool (20) in a bore (16) of a lug (15) on the holder movement along an axis (Z).
