Dithering stages aid resolution enhancement
Two new high-speed x-y dithering stages are designed for use in resolution enhancement and scanning applications.
Integrated ultra-long-life piezoelectric drives provide subnanometre position resolution, important for high-resolution interlacing applications where the optical resolution of a CCD or CMOS sensor is increased by shifting it at high frequency between pixel positions.
Open loop (P-713) and closed loop (P-714) models are available.
Both versions were specifically designed for highly dynamic scanning and tracking tasks.
The closed-loop version provides higher linearity, the open loop version costs less.
The stages feature a very low profile of only 6mm for easy integration in various other applications such as scanning microscopy or in static nanopositioning tasks.
A variety of standard and low-cost OEM controllers in analogue and digital design is available to drive these stages. Request a free brochure from PI (Physik Instrumente) ...
