N2 - An optical scanning system was commissioned and further developed in the Detector Laboratory of Helsinki Institute of Physics and University of Helsinki. It was designed to automatically scan, perform on-line analysis and to classify the overall quality of GEM-foils especially of the GEM-TPC detectors for Super-FRS at FAIR. The optical scanning system consists of precision positioning table, lighting, optics and operating system with analysis software. It has active scanning area of 95 x 95 cm(2) and it can study this area with the minimum resolution of 128 lp/mm. Performance of the system and first results from the GEM-foil uniformity and quality analysis are presented. (C) 2011 Elsevier B.V. All rights reserved.
