Dual-axis Pitch and Roll Stage

The PR10-60-01 (pictured) is driven by stepper motors and the PR10-60-02 is driven by brushless servo motors with quadrature incremental optical encoders.
The Pitch axis (lower stage) is a high precision goniometer stage which features preloaded cross roller guides and a high ratio worm drive for smooth motion over a range of travel of +/- 10 degrees. It has a typical accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees. Additionally, this axis has end-of-travel limit switches.
The 60 mm diameter Roll axis (upper stage) has a 90:1 gear ratio for smooth motion and has a precise pattern of threaded holes for fixtures or tooling.  This axis has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees. The Roll axis has a Home signal for initialization.
Each axis features a calibrated scale to visually display the angle. The maximum speed with stepper motors is 14 degrees/second and 45 degrees/second with servo motors. 
The knobs of the stepper motors can be replaced with optional optical encoders for position verification.
The resolution of the PR10-60-01 stepper motor driven duel-axis stage depends on the resolution of the step 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 a10 micro-steps per step stepper motor driver or an encoder with a resolution of 500 cycles per revolution.
The PR10-60-02 that features servo motors and optical quadrature encoders are used for very precise closed loop operation and greater speeds. 
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.
