Equipment Solutions

Forestville CA --The LFA-2010 Linear Focus Actuator from Equipment Solutions is a high performance compact motion control positioner, specifically developed for optical applications requiring both high precision and high speed positioning over a short to medium stroke. The LFA-2010 actuator has a 10 mm range of motion with <50 nanometer positioning repeatability, and a small step response of time of <3 milliseconds. This high force, low noise voice coil motor is typically configured with an analog position feedback sensor and can be optionally equipped with a 1um resolution digital quadrature feedback element.

An important feature of this product is it's innovative tubular architecture. This allows the 20 mm clear optical path to go directly through the middle of the motor. The patented dual 'Flexures system' has zero stiction/friction. For mounting optics a standard C-mount is provided, or an optional 12.7mm diameter lens socket. The C-mount provides options for adapters to common microscope objectives like DIN or M25 or M26. The LFA-2010 Linear Focus Actuator is well suited for optical focusing and other micropositioning applications such as scanning interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, biotechnology, and semiconductor test equipment.
