New Scale Technologies Inc. has announced the SQL-3405, motorized linear positioning stages for biological research, optical instruments and other micropositioning applications. The closed-loop stages measure 25 × 25 × 10 mm and are driven by an integrated piezoelectric Squiggle motor that provides precise incremental motion of 100 nm. A position sensor provides closed-loop control with 10-μm resolution and a 5-mm travel range. The stages use precision ball bearing guides and are easily assembled to create X-Y and X-Y-Z systems. Maximum operating speed is 5 mm/s.
