Adjustment equipment for optical systems

摘要

The tower (1) has adjusting devices (20, 90) rotatable independent of each other relative to a base (3). One of the adjusting devices is rotatable in an adjusting position (Y) and movable relative to the base in axially limited manner such that the device protrudes from the other adjusting device in the adjusting position than that in a securing position. A force storage exerts axial force on the former adjusting device from the securing position toward the adjusting position. The former device is engaged with the base by a stop unit in the securing position.
