OES motorized stages provide positional accuracy to 0.05 degrees with repeatability of +/- 0.01 degrees.
Optimal Engineering Systems (OES) released three Yaw-Pitch-Roll stages: the YPR100-10-15-01 (stepper motor driven), the YPR100-10-15-02 (brushless servo motor driven) and the YPR100-10-15-03 (DC servo motor driven). The Yaw axis (bottom stage) is capable of rotation of large angles and features a 180:1 ratio gear. The positional accuracy is 0.05 degrees and repeatability is +/- 0.01 degrees. The Pitch axis (middle stage) has cross roller guides and a range of travel of +/- 10 degrees and has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees. The Roll axis (top stage) has cross roller guides and a range of travel of +/- 15 degrees and the 65mm x 65mm table has a precise pattern of threaded holes for fixtures or tooling. This stage has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees and the total center deflection for all axes is 0.03mm. The rotation center height is 50mm. The maximum speed with stepper motors is 14 degrees/second and 90 degrees/second with servo motors.
