Dual-axis Pitch and Roll Stage

Home > Motorized Pitch and Roll Stages 


The precise measurements of angles and the curvature of objects are easily determined using OES' Pitch and Roll Stages.   The Pitch axis (lower stage) is a high precision goniometer stage which features preloaded cross roller guides and a 1 to 296 ratio worm drive for smooth motion over a range of travel of +/- 45 degrees and has a typical accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees.

The roll axis (upper stage) is also a high precision goniometer stage featuring preloaded cross roller guides and a 1:352 gear ratio worm drive for smooth motion over a range of travel of +/- 10 degrees. This stage has a 65 mm x 65 mm table and also has a typical accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees.  Additionally, each axis has end-of-travel limit switches. 

The PR120-45-10-01 and the PR120-45-10-04 which has Optical Encoders for position verification, are both stepper motor driven.  The PR120-45-10-02 is driven by Three Phase Servo motors and the PR120-45-10-03 is driven by DC Servo motors; and each have Quardrature Incremental Encoders for the higher speeds, resolution, and repeatability of closed loop servo systems. 

Each axis features an adjustable calibrated scale to visually display the angle of rotation. The maximum speed with stepper motors is 14 degrees/second and 45 degrees/second with servo motors.  The resolution of the PR100-45-01 stepper motor driven duel-axis stage depends on the resolution of the stepper motor driver resolution or the optical encoder if a servo motor is used. A resolution of 0.001 degrees equivalent to 3.6 arc-sec can be achieved using a 10 micro-steps per step stepper motor driver or an encoder with a resolution of 500 cycles per revolution.

The Dual-axis Pitch and Roll Stages require a Motion Controller that can be ordered as a complete plug-and-play system with joystick, trackball, and keypad.
