Optimal Engineering Systems (OES) has released a new series of three-axis high precision Yaw, Pitch, and Roll Stages capable of rotating an object around a fixed point in space on a spherical surface. The Yaw (lower) axis features ±10° of travel and the Pitch (middle) axis have ±15° of travel and the Roll (upper) axis has 360° of continuous rotation in clockwise or counterclockwise directions. The 100mm diameter rotary table has a precision pattern of threaded holes for mounting cameras, lasers, mirrors, tooling, and fixtures weighing up to 5.0kg (11 lb). Typically, Yaw, Pitch, and Roll Stages can be for used for: Identifying crystals, examining cutting edges of medical instruments, estimating hyperspectral bidirectional reflectance, gloss measurements, measurements of radiation patterns of LEDs, directing lasers, aligning mirrors, and manufacturing quartz oscillator plates using quartz cutting X-rays.

The YPR-10-15-100 Series of three-axis stages have four motor options, The -01 option is Stepper Motor Driven with knobs for manual adjustments. The -02 option is driven by Three-Phase Brushless DC Servo Motors with Quadrature Optical Encoders, and -03 option is Brushed DC Servo Motors driven with Quadrature Optical Encoders. The -04 option is Stepper Motors Driven with Quadrature Optical Encoders for position verification.

The YPR-10-15-100-01 three-axis (dual Goniometers and Rotary) Stepper Motor driven stage (pictured) features ±0.01° of repeatability, 0.05° accuracy and 0.002° resolution with a 10 micro step-per-step micro-stepping driver. Greater precision and faster speeds can be achieved with the Servo Motor options in this series of stages.

The Yaw-axis features a precision ground 420:1 ratio worm gear, the Pitch-axis a 300:1, and Roll-axis a 180:1 ratio. The footprint of the YPR-10-15-100 Yaw, Pitch, and Roll Stage is just 169mm by 169mm. The Yaw-axis and Pitch-axis have End-of-Travel limit switches, and the Roll-axis has a Home switch.
These stages require a Motion Controller that can be ordered Plug-and-Play with Multi-axis Controller, Joystick, and Keypad.
