OptoSigma 124-0070-I Rotation Stage
Rotation stages permit the precise angular adjustment of components. These stages use plain brass bearings to provide coarse adjustment over a full 360° circle. A scale around the circumference provides an indication of the angle. Once set approximately in place the stage may be locked by means of a clamp screw and then fine adjusted by a micrometer (fine pitch screw is used for the 25mm stage). The sizes of these stages are such that they may be mounted together with translation stages to form compound motion devices.
