The company OEG GmbH was founded in 1991 and deals with the development and production of high-precision automatic optical measuring systems for industry and research. OEG GmbH focuses on measuring systems for optical, geometric and physical parameters. We are proud that OEG devices are now installed on all continents. This fact proves the efficiency and innovative strength of the OEG engineers and technicians. In addition to other branches of industry, OEG GmbH has numerous customers in semiconductor technology. The core product is the fully automatic contact angle measuring device SURFTENS WH 300. With a wafer robot, load port, SECS/GEM interface and a fully automatic measurement process, it meets all the requirements for use in highly automated wafer fabs. OEG GmbH also offers devices for research in the semiconductor sector. These include the precision diamond scriber MR 200, the wafer stress measuring device FLATSCAN and various other types of manual and semi-automatic contact angle measuring devices. The product range is supplemented by an image processing system for criticle dimension (CD) measurement, which can be retrofitted to existing microscopes.
