MRH-series
MRH meets the control requirements for small angles with its configuration of precision bearings both above and below, enabling excellent coaxiality and continuous rotation capability. The center through-hole, depending on the model, accommodates lens requirements ranging from 25.4mm to 101.6mm, and can be combined with external optical components using the M6 and M4 holes on the platform's top.
