Description
PPO and PPS levers are driven by our superior MPO stack-actuators. The high strain of these stacks allows for smaller constructions at given displacements. Our levers are equipped with electro-eroded flexures. This is a difference to other suppliers. Flexures avoid friction (wear, non-accuracies) and also micro-cracks, which would reduce life-time. The moving platforms (10×13 mm) are being guided in parallel. Thus PP0 and PPS are not simple drives, but also guidances.
PPS are equipped with strain-gage (SGS) full-bridges, which care for temperature-compensated measuring and controlling positions.
