Patent

CA 2405353

A three axis optical component actuator mechanism is disclosed using two electromagnetic coil actuators and a common stator assembly. In the preferred embodiment the optical component is coupled to the carnage and the carriage is controllable in two axes using electromagnets. A third axis is controllable using a linear motor. The carriage is resiliently mounted within the stator assembly with a plurality of magnetic flux air gaps defined within. Advantageously the disclosed three-axis optical component actuation mechanism has a high frequency response as well as inexpensive cost of manufacturing. In an alternative embodiment a three axis electromagnetic coil actuator is shown having precise travel without the need for expensive linear bearing assemblies.
