The PT200 Pan-Tilt Stage is a combination of two 200 mm (7.874 in.) rotary stages. set at a 90 degrees angle to each other. The rotary stages of each Pan-Tilt stage features a high repeatability of 0.005 degrees (18 arc-sec), a positional accuracy of 0.005 degrees (18 arc-sec), and a resolution of 0.001 degrees (3.6 arc-sec) when 10 Micro-steps per Step Motor Driver is in use. These Pan (horizontal table)-Tilt (vertical table) stages are deal for: Scanning, testing, inspection, assembly, positioning, laser and micro machining, pointing optics and cameras, and other applications.
The pan and tilt axes on both stages have precision V-grove and crossed roller travel guides and are driven by a worm gear with just of 0.005 degrees (18 arc-sec) of backlash.
Each axis is driven by a standard bi-directional stepper motor with a knob for manual adjustments and each rotary axis has a vernier scale for setup. The knob on each motor can be replaced with an optical encoder for position verification. Travel speed of each axis is 12 degrees per second with the stepper motors. For higher speeds and closed loop operation, servo motors are also available.
The PT200 Pan-Tilt Stages can be ordered as complete plug-and-play systems with a
Motion Controllers
, joystick, trackball or keypad. |
