The P-736.ZR Large Aperture piezo-Z nanopositioning system from PI LP (Auburn, MA) is designed for imaging and fast focusing applications. It consists of a large-aperture piezo stage and a digital controller. The flexure-guided piezo nanopositioning stages are optimized for high resolution and fast step and settle. The system enables travel ranges of up to 220 μm with subnanometer closed-loop resolution. The digital nanopositioning controllers can be switched between focus tracking and closed-loop positioning, and also accommodate fast focus and freeze applications. The system is equipped with a compact digital servo piezo controller, as well as user interfaces such as USB, SPI, RS-232, and real-time analog.
