High speed, ultra-high resolution phase shifters Nanopositioning specialists Physik Instrument have introduced the S-303 series of high-speed phase shifters with angstrom level resolution. These compact and extremely responsive systems are based on a tripod piezo drive providing up to 2µm of movement. The 25kHz resonant frequency offers sub-millisecond response and settling dynamics. The shifters are designed to accommodate mirrors and other optics up to 25mm diameter and they may be mounted in any orientation.
