Picomotor Actuator, 1 in. Travel, 30 nm Resolution, 9.5 mm Shank

The 8302 Picomotor Actuator is an ideal device for motorizing fine-positioning stages and mounts in your optical or mechanical systems. Use it with our optomechanical translation stages or your own custom devices. It has better than 30 nm resolution with minimal backlash over a 1 inch (25.4 mm) travel range, and can exert a 5 lb. (22-N) force. It has exceptional long-term stability and the ability to hold its position with no power applied. These last two features make the Picomotor actuator unique among motion-control devices and ideal for typical set and hold applications. Such applications include precision control of sample holders inside cold and/or vacuum chambers, hands-off adjustment of hard-to-reach mirror mounts, or adjustments of optical mounts that are sensitive to forces applied while twisting a knob. For example optimizing the alignment of a laser cavity or adjusting the pointing of a beam over a long distance. The standard 0.375 in (9.5 mm) shank of the Model 8302 lets it fit into standard micrometer mounting holes. Use these Picomotor actuators with our Model 8742 Picomotor Controller/Driver or Model 8703 TTL/Analog driver. Contact us for custom configurations and volume pricing.
