Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsPI (Physik Instrumente) L.P. has introduced the E-709, a piezo nanopositioning controller that provides digital functionality in the size of a paperback for the price of analog. Fifth-order polynomial digital linearization ensures higher accuracy than analog, and two notch filters allow faster response and piezo operation at higher frequencies. A fast servo update rate also ensures responsiveness. The digital-to-analog converter in-the-loop architecture guarantees positional stability. The system is supplied with USB, RS-232, real-time analog and transistor-transistor logic high-speed...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueWafer Measurement SystemThe NEXIV VMZ-NWL 200 from Nikon is an automatic wafer measurement system developed to solve the challenges of wafer metrology in the back-end of the semiconductor manufacturing process.
