Newport MKS Picomotor Actuator, Vacuum Compatible, 12.7 mm Travel, 12x0.5 mm Thread 8321-V

The 8321-V Vacuum Compatible Picomotor™ Actuator has 0.5 inch (12.7 mm) travel, and is an ideal device for motorizing fine-positioning stages and mounts in your optical or mechanical systems. Use it with our opto-mechanical translation stages or your own custom devices. It has better than 30-nm resolution with minimal backlash, and can exert a 5-lb (22-N) force. Moreover, it offers exceptional long-term stability and the ability to hold their position with no power applied. These last two features make the Picomotor 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 (like those in the center of a large setup), 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). 12 x 0.5 mm threads are used for mounting.
