Optical Positioning System Features Zero Translation August 12, 2008
The LFA-1012 linear focus actuator relies on a patented zero-translation tangential flexure for high speed travel. Suitable for a range of applications from optical focusing to semiconductor test equipment, the system features a clear aperture, a 10-mm stroke length, and a standard 12-mm optics mount or an optional DIN mount for use on microscopes. It also features a frictionless, closed loop, non-contact sub-micron resolution linear displacement sensor exhibiting a high bandwidth and low noise. Other features include a positioning resolution of 150 nm, repeatability of 200 nm short term and 50 ppm/1,000 hours long term with 2.2 lbs. of continuous and 3.5 lbs. peak force, and a clean-room compatible, ±12 to ± 24 Vdc at 1A voice-coil motor.
