Last week, four lasers were projected into the skies above the European Southern Observatory’s (ESO’s) Paranal site in Chile. The lasers are each used to create an artificial star, which astronomers use to measure and then correct the blur caused by Earth's atmosphere. The striking launch of these lasers, one from each of the eight-metre telescopes at Paranal, is a significant milestone of the GRAVITY+ project — a large and complex upgrade to ESO’s Very Large Telescope Interferometer (VLTI). GRAVITY+ unlocks a greater observing power and a much wider sky coverage for the VLTI than previously possible.
About
Photonics is a key enabler for progress in semiconductor manufacturing, quantum technology, and advanced optical systems. These fields require extreme precision and multidisciplinary integration. The SPIE Photonics West Exhibition brings together industry and research to showcase innovations that advance imaging, sensing, and optical engineering. It provides a platform for collaboration and technological development in photonics.

Recent highlight: Laser Guide Star systems for ESO
Our expertise in photonics is demonstrated through the Laser Projection Systems developed by Demcon focal in collaboration with TNO for the European Southern Observatory (ESO). These systems, now operational at the Very Large Telescope (VLT) in Chile, use advanced laser technology and adaptive optics to enable high-resolution astronomical imaging. This capability is essential for observing exoplanets and studying phenomena near the Milky Way’s supermassive black hole.
