Abstract

An optical element holding device adjusts an optical element about a first and second axis and includes a main support, and a first plate-shaped support mounted on the main support via a first flexure bearing. The first support can pivot about the first axis. A second support is mounted on the first support via a second flexure bearing and can pivot about the second axis and fasten to the optical element. A first and second actuating element are actuated from a same side of the optical element holding device. A transmission device connected to the first and the second supports transmits the second actuating element movement acting on the transmission device into a pivoting movement of the second support about the second axis. The pivoting positions of the first and second supports can be set by the actuating elements and the second axis is oriented substantially perpendicularly to the plate-shaped first support.
