Thorlabs has expanded its piezoelectric line to include new types of piezoelectric actuators, low-voltage piezoelectric chips, and discrete stacks with through holes, enabling a higher level of flexibility when integrating the actuators into other devices. These chips are ideal for laser tuning, micro-dispensing, and life-science applications. 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.
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.
