Aerotech Gimbals Offer High Accuracy Positioning
Economical AMG-GR gear-driven motorized gimbals from Aerotech provide numerous options for high accuracy positioning applications.
A series of gear-driven motorized gimbals for high-accuracy elevation-over-azimuth positioning has been introduced by Aerotech. The new AMG-GR two-axis optical mounts are available in numerous standard travel ranges and customized travels are easily accommodated from 90 degrees to continuous rotation. Accuracy of ±10 arc sec and a variety of motor types, and cell designs make these gimbal mounts appropriate for applications ranging from sensor calibration to laser beam steering. Standard circular cells range from 100-300 mm diameter. Mounting options include a centered (balanced) cell or a front-surface reflection configuration. The gimbals are available with either brushless servo or stepper motors, with a full range of matching drives and controls. Vacuum-compatible versions are also available. A direct encoder option allows increased accuracy and repeatability. Special configurations accommodate non-circular optics, cameras, sensors, and round optics larger than 300 mm in diameter. The gimbal’s modular-design approach allows each mirror cell to be easily modified or replaced to accommodate sensors or other asymmetrically-shaped payloads.
