Linear Actuator with Moving Magnet and Air Bearing
Many optics and photonics applications require linear limited travel fine motion with high precision. Redirecting laser beams requires near perfect travel without any runout in X and Y directions while travelling in the Z direction. This precision stage uses moving magnet linear motor technology to apply force in the Z direction. When coupled to a linear absolute encoder positioning and precision can be realized in the nanometer resolution range. The Air Bearing helps to stabilize the motion and eliminate nearly all unwanted travel in X and Y.
