Three-axis Yaw, Pitch and Roll Stage

The PYR-45-15-60 Series of Three-axis Pitch, Yaw, and Roll Stages from OES (Optimal Engineering Systems, Inc.) are the integration of a 60 mm diameter rotary stage (upper axis) capable of 360 degrees of continuous operation mounted with the table perpendicular to the table of the Yaw stage (middle axis) goniometer. The middle goniometer stage has a range of +/- 15 degrees and the lower goniometer stage has a +/- 10 degrees range.  These compact three-axis Pitch, Yaw, and Roll stages feature four motor options to meet the precision and speed of travel requirements of an application. 

Depending on the levels of precision and speed of travel requirements, four motor options are available.  The Stepper Motor Driven Stage (-01 option pictured) has knobs at the back of the stepper motors for manual adjustments. With a 10 microsteps-per-step motor driver the repeatability of the stages is +/- 0.01 degrees and travel speeds of 30 degrees-per-second (roll stage) and 14 degrees-per-second (yaw and pitch stages) can be achieved.  Option -02 is driven by Three Phase-Servo Motors with Quadrature Optical Encoders, and option -03 is Brushed DC Servo Motor Driven with Quadrature Optical Encoders. The servo driven stages in a closed loop offer the highest precision and travel speeds.  The -04 option is Stepper Motor Driven with Quadrature Optical Encoders for position verification.  

These three axis stages are the ideal choices for: Optics, laser scanning, drilling, and machining, reverse engineering, inspection, assembly, measurements, tracking, and positioning. 

The rotary axis has a precision pattern of threaded holes for mounting tooling or fixtures and is equipped with a HOME switch to signal the motion controller for initial HOME positioning.  The goniometer (pitch and yaw) axes are equipped with positive and negative limit switches to signal the motion controller that end of travel is reached.  All axes have calibrated scales for visual inspection.
