AOM300 Optical Mount
Description
Design Features
- Compact two-axis azimuth and elevation design
- Continuous 360 degree elevation range; ??180 degree azimuth range
- Choice of high resolution microstepping or servomotors
- Rectangular and circular cell models
- Custom precision mounting designs are available for centering non-circular payloads
Aerotech's AOM300 series of motorized optical mounts offer extended rotation in the elevation and azimuth axes. The larger AOM300 models offer 360° in the elevation axis and ±180° in the azimuth axis.
This extended travel provides the user with the capability to automatically control AZ/EL throughout the full 360° of travel. This makes the AOM300 ideal for experimental tracking applications. The AOM300-150 and -200 models can handle heavier loads and are available with DC brush, brushless servomotors and stepping motors.
The AOM300 has a large number of encoder options so the user can select the system that is right for them. All AOM300 optical mounts are equipped with accurate home marker references to facilitate accurate and repeatable positioning.
The standard AOM300 cell configuration is designed for circular optics. Special configurations are available to accommodate non-circular optics, cameras, sensors and larger diameter optics. Special larger cells up to 300 mm can be supplied. Please contact us with your requirements.
