A new series of low-cost DC drive motors from Siskiyou Corporation (Grants Pass, OR) enables precise, hands-free adjustment of translation stages and mirror mounts, using a simple, push-button control pad. Specifically, the new 500 series actuators can replace manual screw and micrometer adjusters on Siskiyou’s crossed roller bearing linear stages, kinematic mirror mounts, and IS OGP beam steering assembly for microscopes. The hand-held controller for operating these actuators offers two preset drive speeds (0.3 mm/s and 0.1 mm/second), as well as an adjustable low speed range (from 10 μm/s to 30 μm/s). The latter enables consistent, small moves (down to 1.0 μm) with a single, short button press.

The 500 series actuators for translation stages are available with either 12 mm or 25 mm of travel. The models intended for mirror mounts offer 5 mm or 8 mm of total travel. For all of these 500 series actuators, built-in limit switches prevent damage by ensuring that the stage or mount cannot be driven past its intended end of travel.
