Motorized Theta 2 Theta Stage

Model : MRS-T2T-200
360° limitless movement
Preloaded ball bearing guides

Holmarc's theta 2 theta stage consists of two rotation stages arranged in such a way that axis of rotation for both the stages are same. Both stages have preloaded ball bearing guides for wobble free rotation and positioning. 360° limitless movement is possible for inner and outer stages. Holmarc manufactures these stages with manual as well as motorized drive configurations. Rotary graduations are provided in 1°/ 2° with appropriate vernier graduations depending on the size of the stage. For motorized rotation stage, worm and gear is our standard drive mechanism. Surfaces of both stages are provided with M6 tapped holes for mounting components and subassemblies. Holmarc manufactures custom theta 2 theta stages to suit specific applications as well.

This robotic positioner has two rotary axis (theta X and theta Z) and two linear axis (X and Y ), all driven by stepper / BLDC servo motors. The base stage is X axis stage with 500 mm traverse. The theta-X rotation stage is fixed to the carriage of the X stage. Y axis (second linear stage) having a traverse of 300 mm is fixed to the top of the X-theta rotation stage. Vertical bracket is fixed to the carriage of Y axis. Theta Z stage is fixed to the top of the angle bracket. Antenna holder is fixed to the theta-Z stage. Both theta x and theta Z stages have 360 degree rotation and 1 degree graduation for reference. Construction material is aluminium alloy for clean room compatibility and for keeping the self weight of the stage as minimum as possible.
