AUBURN, Mass. — 
The F-712.HA2 and F-712.MA2 automated alignment engines from Physik Instrumente LP are designed for silicon photonics applications including three- to six-axis mechanisms, controllers with firmware-based alignment algorithms and software tools for the packing, planar testing and inspection markets.
The systems achieve alignment times of <1 s for single and double-sided alignment tasks, with all axes driven by one controller or one software interface using one global coordinate system. Interdependencies of axes are automatically compensated for and integrated coarse-fine solutions deliver 25-mm, closed-loop motion for first light and 100-μm, high-speed, piezo-flexure-based nano-align motion in X, Y and Z. Longer linear travel ranges are possible.
The advanced alignment systems are based on a specialized digital motion controller with embedded advanced alignment, tracking functionality and a hybrid precision scanning and tracking mechanism, combining the advantages of piezoelectric on servo-motorized drives.
