Developed for optical positioning applications, the compact LFA-1012 linear focus actuator from Equipment Solutions Inc. offers a zero-translation tangential flexure for high-speed travel. It features a clear aperture, 10-mm stroke length and a standard 12-mm optics mount (or an optional DIN mount for use on microscopes). The frictionless, closed-loop, noncontact, submicron-resolution linear displacement sensor has high bandwidth and low noise to ensure high responsiveness and precision. The actuator offers 150-nm positioning resolution, repeatability of 200 nm (short term) and 50 pulses per minute per 1000 h (long term) with 2.2-lb continuous and 3.5-lb peak force. It is cleanroom-compatible and operates in any orientation.
