APP Systems Services provides a wide range of equipment and engineering solutions in the R&D sector especially in material science, semiconductor and related fields. The MagVision Kerr System is a microscopy system that characterizes magnetic devices and its critical effect on final product yield. The core technology stems from Nanyang Technological University (NTU) Physics Laboratory's discovery on a novel technique of Faraday Effect Reduction on the objective lens to better establish Kerr imaging in a magnetic domain process.
