ANT20G Single-Axis Direct-Drive Goniometer
Our ANT20G goniometers are designed for high-speed, ultra-precise positioning applications such as the angular alignment of components. This unique design utilizes our best-in-class direct-drive noncontact motor technology and provides an industry-leading positioning speed of up to 150 degrees per second.

Design Features
- Noncontact, non-cogging, frictionless direct-drive for zero backlash or hysteresis
- High speed (150 degrees/s)
- High resolution (0.05 arc sec)
- Excellent in-position stability
- Large 20 degree rotation angle
- Orthogonal mounting of two cradles provides rotation about the same point
- No maintenance
- Compact design
High-precision bearings, direct on-axis encoder feedback and noncontact and non-cogging direct-drive technology ensure the highest level of performance and make excellent repeatability and in-position stability a reality. The goniometer cradles can be mounted orthogonally to provide pitch and roll about the same point in space. Combining this with a rotary stage under the orthogonal assembly adds a third rotation axis (pitch, roll, yaw) through the same point.
The critical elements of the ANT20G goniometers, as with all other ANT series nanopositioners, were selected to operate in a 24/7 manufacturing environment. Unlike worm- or piezo-driven goniometers, the ANT20G series will not require periodic adjustment or maintenance. This will ensure many years of trouble-free operation. The ANT20G cradles are available in four sizes.

Integration (Required)
Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.
| Option | Description |
| -TAS | Integration - Test as system Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration. |
| -TAC | Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system. |
