Ultra-precise pointing & tracking
The AOM-HG hybrid gimbal features a direct-drive, large-travel azimuth (AZ) axis, and screw-driven elevation (EL) axis driven by a directly coupled brushless servo motor. Optimized for high accuracy, it features a low mirror height for maximum compactness and ultra-fine, highly repeatable stepping performance to provide highly capable pointing and tracking motion. Both axes have sub-arcsecond feedback resolution. The AOM-HG is available with 16-, 20- 24- and 30-inch mirror cell diameters, and the small cell thickness allows for reflections with high angles of incidence. Special environmental preparation options are available for operation in cleanrooms and vacuum chambers.
Multi-Axis Versatility
AOM-HG hybrid gimbals are highly configurable, with a variety of options available to provide an effective and stable platform for applications that require excellent positioning resolution and pointing stability. Three azimuth options offer increasing torque specifications and payload capacity, with travel options ranging from ±5° to ±170°, thereby preventing cable wind-up. The elevation axis is configurable for the desired optic size, ranging from 16 in. to 30 in., with two optional mirror cell arrangements. In addition to operation in atmospheric environments, AOM-HG gimbals can be prepared for use in clean rooms and vacuum chambers.
Customizable Design Features
The AOM-HG is an especially versatile motion platform, able to be customized to meet your specific application requirements. Whether you need a mirror cell with non-standard geometry and anti-distortion mirror clamps, custom-tailored counterbalancing or even a special slip ring, our highly experienced engineering teams have you covered.
