TScan - Tower Scanners

TScan is a fast and ultra-accurate planar near-field scanner with the latest motor drive and encoder technologies. High acceleration of the linear motors for stepped and continuous mode operation optimizes the performance and cost of the scanner. Excellent manufacturing precision combined with direct readout high resolution linear encoders and careful alignment ensure unrivaled mechanical positioning accuracy and planarity.
