Aerotech AOM130 Optical Mount

Designed to position large, heavy optics up to 609.6mm in diameter


AOM130 series mounts have been designed to position large, heavy optics to 609.6 mm 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-second resolution.


  • 360 degree rotation in azimuth and elevation
  • Excellent thermal and vibration stability
  • Standard models 152.4 mm through 609.6 mm optic diameters
  • Patented* sub-arc-second resolution drive
  • Negligible backlash and creep
  • Non-marring set screws on retaining clips
  • Custom precision mounting designs are available for centering non-circular payloads

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 ensures smooth, low stiction and backlash-free motion. To obtain 360° rotation, simply release 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 nonmarring set screws permit rigid placement of various optic thicknesses.
