8816 Picomotor Piezo Gimbal Mount

The 8816 Picomotor Gimbal Mount combines the precision of our ULTIMA^® Gimbal mounts with the resolution of our Picomotor™ actuator to provide the ultimate in precision motorized optical alignment for 2.0 in. (50.8 mm) diameter optics. The angular range is ±4°. This mount can be driven by our Open-Loop Picomotor Controller/Driver.

Gimbal Mirror Mount

A gimbal mount has axes of rotation which intersect at the center front surface of the optic. When the mount is adjusted, only the beam's angle changes, not its length. In contrast, a non-gimbal mount will shorten or lengthen a beam path as angle is adjusted.

Compact Design

The compact Picomotor actuator housing adds only 0.75 in. (19.1 mm) to the overall thickness of the mounts, allowing these mounts to be located where needed on a crowded optical table or breadboard.

0.7 µrad Resolution

Our Picomotor actuators allow for an angular resolution of 0.7 µrad, allowing for very small, controlled movements of your optics. The Picomotor actuator offers the additional advantage of using the integrated knobs for quick, manual adjustment of all axes.

Set-and-Forget Long-Term Stability

The Picomotor actuator moves when voltage is applied to the piezo, changing its length and in turn moving the jaws which turn the screw. When no power is applied, the actuator does not move. You can feel confident that your mount will stay put, even when you power down your system.

Smooth and Reliable Motorized Adjustment

Sapphire seats and optimized spring location and force provides for smooth, reliable motorized adjustment while maintaining a high level of thermal and mechanical stability.

Easy-to-Use, Flexible Picomotor Controllers

Our Open-Loop Picomotor controllers and drivers are modular. You can daisy-chain up to 31 drivers together with four channels each, so you can have a network of up to 124 standard Picomotor actuators. You have two interface options with the controller system: hand pad or computer, both providing plug-and-play use. Alternatively, you may choose to use our TTL/Analog Picomotor driver.
