Three-Axis Positioning Stages

OES introduced its YPR-10-15-60 Series of three-axis yaw, pitch, and roll stages that feature four motor options. The series is the integration of a 60mm diameter rotary stage (upper axis) capable of 360 degrees of continuous operation, and two goniometers (middle and lower axes). The middle stage has a range of +/- 15 degrees and the lower stage has a +/- 10 degrees range. The four motor options include the -01 option is stepper motor driven and has knobs for manual adjustments. The stepper motors with a 10 micro-steps per step motor driver have a repeatability of +/- 0.01 degree and travel speeds of 30 degrees-per-second (roll stage) and 14 degrees-per-second (pitch and yaw stages). Option -02 is driven by three phase-servo motors, and option -03 is DC servo motor driven. The -04 option is stepper motor driven with quadrature optical encoders for position verification.
