Key Features

The RT75S is the smallest rotary stage in the RT-S series, making it ideally suited for precise handling of small objects. Its small size and low mass allow for an easy integration in multi-axes systems. It is compatible with many Z-stages and can be equipped with a slipring to enable mounting of an XY linear stage on top of the rotary stage.
