The AOM130M series of gimbal mounts position optical components
as large as 600 mm (24 inches) 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 Assure 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, which
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 (24 in)
AOM130M series motor-driven gimbal mounts are available in six
standard sizes that accommodate 152.4, 228.6, 04.8, 406.4, 508.0,
and 609.6 mm (6, 9, 12, 16, 20 and 24 inch) diameter optical components.
In addition, adapters for 127.0, 203.2, and 254.0 mm (5, 8, and
10 inch) diameter optics are available as accessories, providing
mounting capability for virtually all standard optic elements
between 127.0 and 609.6 mm (5 to 24 inches) 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), and manually rotating each axis
anywhere in a 360° range, and reclamping. Neither of the manual
adjustments disturbs the precision motorized drive assembly.
Wide Range of Resolutions and Drive Choices
Depending upon the motor selected (microstepping or servo) and
the controller resolution setting, resolution to 0.008 arc second
is achievable with the AOM130M. Some commonly specified resolutions
and corresponding mount resolutions are listed in the specifications
table. For mount resolutions other than those listed in the specifications
table, please contact us.
A home marker encoder and positioning knob are options for microstepping
versions. The DC servomotor is equipped with a rotary encoder
with marker-to-enable closed-loop positioning feedback.
