Abstract
In a device for displacing an optical element 2 along the optical axis, in particular a lens of large diameter in an objective, the optical element 2 is supported by a retaining ring 1 acted upon by an adjusting device 8 with a coarse adjusting drive 9 and a fine adjusting drive 10. The retaining ring 1 is connected, via solid joints 4 which have a substantially greater stiffness transverse to the optical axis than along the optical axis, to a supporting ring 3 which is arranged on a mount or which forms a part thereof. The solid joints 4 are arranged between the retaining ring 1 and the supporting ring 3 in such a way that the retaining ring 1 can be displaced along the optical axis upon actuation of the adjusting device 8.
