For more details see the Operation tab.Ĭhips After Binder Burnout and Sintering Thorlabs' In-House Piezoelectric Manufacturing Please note that when mounting a load onto the piezoelectric chip, the force should be directed along the actuator's axis of displacement. The actual value of the maximum displacement varies for each item and must be experimentally determined however, the maximum displacement will always be larger than the free stroke displacement. The maximum displacement of these actuators is achieved when they are preloaded with the maximum displacement load, which is specified for each product. This high accuracy makes it significantly easier to design devices around our piezoelectric chips. Through a precision grinding process, the accuracy of the design height is ensured to better than ±5 µm. These compact piezoelectric chips can be easily integrated into systems for precision movement and provide maximum free stroke displacements from 1.8 µm to 3.0 µm. They are available with a drive voltage range of 0 - 150 V for a complete list of specifications, see the table below. The central through hole is ideal for laser tuning and micro-dispensing applications. The multilayer design enables high resonant frequencies and sub-millisecond response times, while the use of interdigitated electrodes minimizes the drive voltage range. Thorlabs' piezoelectric actuators with a central through hole consist of stacked piezoelectric ceramic layers with interdigitated electrodes, as pictured in the diagram to the right.
