One of the innovations that makes the Profilm3D affordable is it’s distributed-APA design. By using three small APAs (amplified piezo actuators) positioned around the turret center-of-gravity, the Profilm3D uses a much smaller volume of piezo material than traditional single-APA profiler designs. Since the total volume of piezo material used is a major cost driver in profilers, this results in significant cost savings. By characterizing the APA motion as a function of voltage and driving the three APAs independently, Filmetrics is able to attain an exceptionally straight and linear turret vertical scan motion.
