Physik Instrumente (PI)
This company’s line of controllers for ultrasonic direct-drive motors and positioning stages offer responsiveness for a range of user requirements, including precision positioning and handling. The small-footprint C-877.1U11 single-axis controller (photo) and low-cost two-axis controller are among the product line’s offerings. Also available is the new C-867.262 multi-phase controller, which allows for extremely smooth motion with velocities below 1µm/s, a critical feature for microscopy and surface nano-metrology. The controllers are delivered with extensive software packages, including dynamic libraries for Windows and Linux operating systems. In addition, a powerful macro programming language is available for automation tasks and standalone operation. — Physik Instrumente (PI) LP, Auburn, Mass.
