The OES YPR-10-15-100 of three-axis high precision yaw, pitch, and roll stages are for identifying crystals; examining cutting edges of medical instruments; and estimating hyperspectral bidirectional reflectance.

Summary points:

  • The YPR-10-15-100 provides high-accuracy rotation for yaw, pitch, and roll, offering 10 degrees (yaw), 15 degrees (pitch), and continuous 360-degrees rotation (roll) for advanced applications.
  • Product is for crystal identification, medical instrument inspection, LED radiation pattern testing, and hyperspectral reflectance, as well as gloss measurement and mirror alignment.
  • Available with four motor configurations, the YPR-10-15-100 delivers repeatability up to 0.01 degrees, with precision control for demanding motion tasks.

VAN NUYS, Calif. – Optimal Engineering Systems Inc. (OES) in Van Nuys, Calif., is introducing the YPR-10-15-100 of three-axis high precision yaw, pitch, and roll stages for identifying crystals; examining cutting edges of medical instruments; and estimating hyperspectral bidirectional reflectance.

The YPR-10-15-100 stages can rotate an object around point on a spherical surface. The yaw (lower) axis features plus-or-minus 10 degrees of travel; the pitch (middle) axis has plus-or-minus 15 degrees of travel; and the roll (upper) axis has 360 degrees of continuous rotation in clockwise or counterclockwise directions.

The 100-millimeter-diameter rotary table has a precision pattern of threaded holes for mounting cameras, lasers, mirrors, tooling, and fixtures that weigh as much as 11 pounds.

Applications

Yaw, pitch, and roll stages also are for gloss test and measurement, measuring radiation patterns of LEDs, directing lasers, aligning mirrors, and manufacturing quartz oscillator plates using quartz cutting X-rays.

The YPR-10-15-100 has four motor options: the -01 option for stepper motor driven with knobs for manual adjustments; the -02 option is driven by three-phase brushless DC servo motors with quadrature optical encoders, the -03 option is brushed DC servo motors driven with quadrature optical encoders; and the -04 option is stepper motors driven with quadrature optical encoders for position verification.

The YPR-10-15-100-01 stepper motor driven stage has plus-or-minus 0.01 degrees of repeatability, 0.05 degrees accuracy, and 0.002 degrees resolution with a 10 micro step-per-step micro-stepping driver.

Tell me more about three-axis yaw, pitch, and roll stages ...

  • A three-axis system uses yaw, pitch, and roll to describe the rotation of an object in 3D space. Yaw refers to the rotation around the vertical axis (left or right). Pitch is the rotation around the horizontal axis (up or down), and roll is the rotation around the axis extending from front to back (tilting side to side). These three rotations are independent and allow an object, like a drone or aircraft, to move fluidly in all directions. Each axis influences the object's orientation, and by controlling these, precise navigation and stabilization are achieved, especially in aerospace and robotics. These stages are key in motion control, sensor calibration, and stabilization algorithms.

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 size of the YPR-10-15-100 yaw, pitch, and roll Stage is 169-millimeter-by 169 mm. 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.
