The invention relates to a device, such as a rotary disk ( 1 ) or a longitudinal slider ( 2 ), for retaining optical components, this device comprising open orifices ( 3 ) arranged next to one another, and a raceway ( 4 ) having detents ( 5 ) being provided in the direction of the arranged orifices ( 3 ), which detents are embodied in such a way that they are to be brought into click-stop engagement with a ball bearing ( 6 ) running along the raceway ( 4 ), in order to hold the device ( 1, 2 ) in a selected position. In order to enable gentle click-stopping of the ball bearing ( 6 ) with a wide capture region, it is proposed that the detents ( 5 ) have, in the running direction, a profile comprising a combination of two arc-shaped profiles ( 10, 11 ), such that an outer profile ( 11 ) of lesser curvature surrounds an inner profile of greater curvature ( 10 ).
