Cedrat Technologies today manufacture 30 different standard amplified piezo actuators (APA). The smallest exhibits a 28-μm stroke with a height of only 6 mm in the direction of actuation. Linear and rotating piezo motors offer micro-positioning on long-stroke of more than 100 mm, with blocking at rest in any position. APAs can provide innovative solutions in many fields, including:
Optics: positioning of mirrors or lenses, focusing, laser cavity tuning, alignment or deformation of fibres, deformation of fiber Bragg gratings (FBG), scanners, choppers, interferometers and modulators.
Mechanics: positioning of tools, clamps, active wedges, damping, active control and generation of ultrasonic or sonic vibrations.
Fluids: proportional valves, pumps, measuring, injections, ink jet and droplet generators.
Electronics: positioning of masks, wafers or magnetic heads, non-magnetic actuation and circuit breakers.
