Abstract

An optical switch actuator moving an optical element into or out of an optical pathway. The optical element is coupled to a movable shuttle and driven by a motor between two rest positions. The motor includes two stationary coils and a magnet attached to the shuttle. The shuttle is magnetically latched in the rest positions. The optical element's position at the extended rest position is controlled with a stop that contacts the shuttle to provide accuracy and precision about multiple axes. The material used to construct the actuator's components aids in repeatedly positioning the optical element with precision.
