Overview

Construction Features

The addition of a larger clear aperture is a key enhancement over previous generations of worm-gear-driven stages. This feature allows the AGR series to address applications requiring a through-hole or accommodations to mount an optic, including articulation of beam polarizing lenses, through-holes for cabling and/or air lines, or vision/camera/inspection applications.

The AGR stage base is fabricated from an aluminum alloy that offers significant weight savings in multi-axis arrangements and other weight critical applications, while providing high structural stiffness and long-term stability.

Each stage is designed with two high-precision angular contact bearings with optimal spacing to provide excellent error motions coupled with high load capacities in a small, compact package.

Flexible Options

Options include flexible motor selections as well as a direct encoder mounted to the stage shaft for outstanding repeatability and to virtually eliminate hysteresis and backlash. Vacuum-compatible versions (for use in pressures as low as 10-6 torr) are also available.

Motor and Drives

Standard AGR stage configurations feature Aerotech’s brushless servomotors. However, all AGR stages can be outfitted with stepper or DC brush motors. A full range of matching drives and controls are available for a complete single-source solution.
