Standard Picomotor Actuators

Picomotor actuators are ideal devices for motorizing fine-positioning stages and mounts in your optical or mechanical systems. Use them with our optomechanical translation stages or your own custom devices. They have better than 30-nm resolution with minimal backlash, and can exert a 5-lb (22-N) force. Moreover, they have exceptional longterm stability and the ability to hold their position with no power applied. These last two features make the Picomotor actuators 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 instance optimizing the alignment of a laser cavity or adjusting the pointing of a beam over a long distance).

The standard sized shanks of the Models 830X and 12X0.5-mm threading of the Models 832X let them fit into standard micrometer mounting holes. The Time Model 8351 gives you a solution for even the smallest application. For rotation without translation, use the Model 8341 rotating shaft.
