AOM130M Gimbal

Description

Design Features

  • Standard models 152.4 mm through 609.6 mm optic diameters
  • Exhibits excellent thermal stability of better than 2 µrad/°C
  • Precise positioning is ensured by sub-arc-second resolution capability
  • Mounting holes are slotted to accommodate English or metric hole pattern
  • Can be supplied prepared for use in vacuum
  • Custom precision mounting designs are available for centering non-circular payloads on the gimbal

The AOM130M series of gimbal mounts position optical components as large as 600 mm in diameter in both azimuth and elevation. The AOM130M mounts provide outstanding stability and sub-arc-second resolution for use in optics and laser experimentation in research or industrial laboratory settings.

Precision Bearings Ensure Accuracy

The AOM130M's precision gimbal pivot ball bearings minimize backlash and reduce stiction. The mirror cell and azimuth bearing systems utilize high-quality preloaded angular contact bearings that permit fully-loaded operation in any orientation, including upside-down.

Excellent Positioning Capability

The AOM130M mounts possess desirable positioning characteristics including 0.75 arc sec unidirectional repeatability, negligible backlash and hysteresis that is typically better than 5 arc sec. The mechanical and thermal stabilities of the AOM130M series are excellent. The rigid castings employed help push resonant frequencies beyond 200 Hz, and thermal stability is better than 2 µrad/°C.

Highly Accurate Limits and Homing System

All AOM130M mounts are equipped with high accuracy limit switches. Combining the output of these switches and the motor's marker signal, Aerotech's motion controllers can position the AOM130M mounts to highly accurate home reference points, typically to within 0.001°.

Standard Sizes to 600 mm

AOM130M series motor-driven gimbal mounts are available in six standard sizes that accommodate 152.4, 228.6, 304.8, 406.4, 508.0 and 609.6 mm diameter optical components. In addition, adapters for 127.0, 203.2 and 254.0 mm diameter optics are available as accessories, providing mounting capability for virtually all standard optic elements between 127.0 and 609.6 mm in diameter.

Full 360° AZ and EL Positioning

High resolution positioning in the range of ±4° is achieved under motor control. Rotational freedom is further extended to a full 360 degrees by unclamping the mirror cell and/or azimuth assembly (a tool is included), manually rotating each axis anywhere in a 360° range, and then reclamping. Neither of the manual adjustments disturbs the precision motorized drive assembly.

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.
-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. This is typically used for spare parts, replacement parts, or items that will not be used or shipped together (ex: stage only). These components may or may not be part of a larger system
