The PG-50 gonio stage performs best in limited space applications due to its compact design. High stiffness motion is achieved through pre-loaded crossed-roller bearings and a precision worm drive. These stages may be mounted in an orthogonal, space-saving arrangement to achieve pitch and roll adjustment. Versions capable of operation in vacuum (10-6) are available. The PG-50 is compatible with the MMC-200 controller. Additional center of rotations are available. Precision Gonio Stage PG-50SM
