Negligible backlash and creep
Non-marring set screws on retaining clips
Custom precision mounting designs are available for centering non-circular payloads on the gimbal

AOM130 series mounts have been designed to position large, heavy optics to 609.6 mm (24 inches) in diameter. These mounts are used in major fusion and high-powered laser research and development projects due to their excellent thermal stability and sub-arc-sec resolution.

AOM130 series optical mounts have 360° rotation capability in both the azimuth and elevation axes. They have ball bearing gimbal pivots to eliminate unwanted motion (cross-talk); movement in azimuth and elevation is orthogonal and decoupled. A unique azimuth bearing system permits operation of a fully-loaded mount in any plane including upside-down. With Aerotech's patented* sub arc second resolution drive, the angular range is quickly achieved while maintaining resolution as fine as 0.026 arc-seconds.

The fine thimble has a 32-division scale for reference. The spring loaded drive mechanism assures smooth, low stiction and backlash-free motion. 360° rotation is obtained by releasing the cell or yoke clamp screws (tool provided). The mount's precision drive mechanism is unaffected when the clamp screws are disengaged. The mount and drive mechanisms feature extremely low backlash and excellent thermal stability (less than two microradians per °C).

Adapters for 5, 8 and 10 inch (127.0, 203.2, and 254.0 mm) optics add versatility and value to the AOM130 series mounts. The optics and/or adapters are held in place with three retaining clips with non-marring set screws. The non-marring set screws permit rigid placement of various optic thicknesses.

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
