ACM Coatings GmbH (subsidiary of Acktar Ltd.)

Acktar is a manufacturer of deep black, light-absorbing coatings and films that are used worldwide to optimize optical systems. In addition to medical technology, the company serves a range of other high-tech industries such as aerospace, semiconductors, automotive, industrial optics, laser technology, and scientific instrumentation.The coatings are applied to various substrates (metals, glass, ceramics, plastics, films) using a patented vacuum process and are characterized by extremely high stray light absorption (up to approximately 99%), high emissivity, low outgassing, and high thermal stability well above 300 °C. Typical applications can be found in space telescopes and satellite optics, the semiconductor sector, cameras and LiDAR systems in vehicles, laser systems, inspection systems, and optical measuring devices.In medical technology, Acktar coatings are used in endoscopes, fluorescence microscopes, and other imaging or diagnostic systems, where they reduce stray light and reflections, thereby improving contrast, measurement accuracy, and detection limits. Thanks to their inorganic composition, low outgassing rates, and suitability for clean room and vacuum conditions, they are suitable for sensitive medical and biomedical applications while supporting compliance with strict material and environmental requirements, including REACH & RoHS.
