Equipment Solutions: Optical Positioning System
Optical positioning system.
Sunnyvale, CA, — Developed for precision optical positioning applications, Equipment Solutions, Inc.'s LFA-1012 Linear Focus Actuator has a patented zero-translation tangential flexure for high-speed travel. The system provides a clear aperture, 10mm (0.394-in.) stroke length and standard 12mm optics mount (or an optional DIN mount for use on microscopes).

The positioning system is especially suitable for optical focusing, scanning, interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, biotechnology, and semiconductor test equipment.

According to the company, a frictionless, closed-loop, non-contact sub-micron resolution linear displacement sensor with high bandwidth and low noise assures high responsiveness and ultra precision. Positioning resolution is stated at 150nm, repeatability is 200nm (short term) and 50 ppm/1000 hr. (long term) with 2.2 lbs. continuous and 3.5 lbs. peak force.

The low inertia, zero stiction/friction, ±12VDC to ±24VDC at 1amp, voice coil motor of the Linear Focus Actuator has very low electrical noise, is clean room-compatible, and can be operated in any orientation. Mounting holes on various surfaces makes mounting easy in new or existing applications.

The corresponding SCA814 Linear Servo Controller is also available — a high-performance single-axis DC motor controller and amplifier that was developed for applications requiring high temporal and spatial servo precision.
