Newport Goniometric CradleUSED
BGM Series goniometric cradles rotate about a transverse axis in space above the platform. They are designed so that orthogonal mounting of two adjacent-size cradles (e.g., BGM50 and BGM80) provides two perpendicular axes of rotation about the same point in space. Single-row ball-bearings and precision-ground, tool-steel races assure smooth rotation with minimal wobble and eccentricity. Position measuring is performed with a 2000 pts/rev. encoder, integral with the motor shaft. All BGM Series stages are equipped with a knurled knob for a manual control.
