The chips can be manufactured with or without pre-attached wires, with holes ranging from Ø2.0 mm to Ø6.0 mm, cross sections ranging from 5.0 mm × 5.0 mm to 10.0 mm × 10.0 mm, and thicknesses under 5.0 mm. Stacks are available in lengths from 5 mm to 100 mm, providing free stroke displacements up to 100 µm. Our in-house manufacturing facility can also be deployed to provide custom dimensions, voltage ranges, and coatings upon request. Leveraging our high-volume production capacity allows us to fulfill high-volume quantity requests with short lead times.
The piezoelectric chips are driven under a maximum voltage of 150 V, providing maximum free stroke displacements from 1.8 µm to 3.0 µm with sub-millisecond response time. Through a precision grinding process, the accuracy of the design height is ensured to better than ±5 µm. The high accuracy makes it significantly easier to design devices around our piezoelectric chips, as it allows the users to have a loose tolerance when choosing their other components, and helps guarantee a better parallelism when employing multiple chips between two substrates.
“Reliability and durability of multilayer piezoelectric actuators are becoming increasingly important as the piezo application fields expand,” commented Cary Zhang, Piezo Product Line Manager. “Thorlabs’ multilayer piezo actuators are based on modified PZT-5H ceramics, which are sintered at low temperatures (<1000 °C) to possess improved characteristics such as low electrical capacity, large displacement, and high stiffness.”
