Motion Control – Linear Focus Actuator from Equipment Solutions

Sunnyvale, CA, —The LFA-1205 Linear Focus Actuator is a high performance compact positioning system.  It was specifically developed for optical applications requiring both high precision and high-speed positioning over a short to medium stroke.  The LFA-1205 is well suited for optical focusing and other micropositioning applications such as scanning interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, bio-technology, semiconductor test equipment.  Note that this motor is normally configured with an analog position feedback sensor and can be optionally equipped with a digital quadrature feedback element.    The key to this products immense success is its novel tubular architecture.  This arrangement provides a means to send the optical path directly through the middle of the motor.  The moving optic attached to the motors ‘C-mount’ is not cantilevered and so has no torques.  The LFA-1205 Linear Focus Actuator is directly compatible with the SCA814 Servo Controlled Amplifier.

  • 12 Millimeter clear aperture
  • 5 millimeters of linear motion
  • <50 nanometer positioning repeatability
  • Small Step Response of <1 millisecond
  • Threaded lens mount
  • 70 x 70 x 50 millimeters, 600 grams

 

 

By design, the LFA-1205 Linear Focus Actuator rotates approximately 0.1 degrees or 1.7 milliradians for every 1 millimeter of translation.  Through manufacturing tolerances only there can be a small amount of pitch and roll motion that is induced during the intended translation.  These small but real error sources are routinely characterized during the manufacturing process  using our AC400 Digital Autocollimator to control product uniformity.
