Spectrogon manufactures and develops optical filters, thin film coatings, and holographic diffraction gratings. Spectrogon US Inc, a subsiduary of Spectrogon AB, market and sell Spectrogon products in the Americas. Spectrogon derives its origin partly from research conducted at the Royal Institute of Technology in Stockholm, and partly from research and development projects at AGA AB, a former major Swedish industrial group. In 1980 we became AGA Optical, which eventually became Spectrogon in 1984. Spectrogon AB became an independent company 1991. With over 90 % in export, our most important markets are Western Europe and North America. More than 80 % of invoiced sales go to OEM in specialised electro-optics markets. These markets include: instrumentation for medical diagnostics, industrial process control, robotics, environmental measurements, optical communications and other related instrumentation.
