Low Cost, High Speed, 150 nm Resolution, Voice Coil Stage for Optical Applications!


motion control - miniature components

Forestville, CA, – A high speed, 150 nanometer (0.000005905512 inches) resolution voice coil stage with an 18 mm (0.709 in.) aperture is ideal for micro positioning and optical focusing applications. The compact, high precision Equipment Solutions’ LFA-3 Linear Focus Actuator, utilizes patented frictionless/stictionless flexures for very high responsiveness and zero mechanical noise. Typical applications include: optical focusing, scanning, interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, biotechnology, and semiconductor test equipment.

The low inertia, ± 12 VDC to ± 24 VDC, @1 amp, voice coil motor of the LFA-3 Linear Focus Actuator has very low electrical noise, 3 mm (0.118 in.) travel, and 813.5 Ncm continuous force (6.0 ft-lbs) 4067 Ncm peak (30 ft-lbs). It is clean room compatible and can be operated in a horizontal or vertical orientation. Standard lens “C” mounts are provided on both the stator and translator elements, and DIN standard microscope objective adapters are available. For easy mounting of the actuator, mounting holes are on several surfaces.

For easy integration into a new or existing application the matching SCA824 Linear Servo Controller is available from Equipment Solutions. It is a high performance single axis DC motor controller and amplifier that was developed for applications requiring high temporal and spatial servo precision.
