The AD Series actuators and ESA Series controllers bring you cost-effective nanometer-scale positioning like conventional piezoelectric devices without their associated hysteresis, creep, settling, and high voltage problems. We have packaged today’s most advanced electrostrictive ceramic materials into a compact micrometer-sized module which mounts on all of our micrometer-compatible components.
Ideal for demanding fiber positioning, waveguide testing, micro-assembly, and probing applications, the AD actuators provide as fine as 40 nm minimum incremental motion with long travel ranges up to 100 mm. An integrated ultra-fine pitch manual screw allows for 13 mm manual adjustment range with a sensitivity better than 0.5 mm. The adjustment knob is precisely marked every 10 mm making it simple to center the electrostrictive fine-motion travel where desired.
