ELT: A Spectacular Eye on the Sky

PICA Stack Actuators from PI for Precise and Reliable Image Stabilization in the World’s Largest Telescope

In the Chilean desert, the European Southern Observatory (ESO) is currently building the largest telescope in the world - the ELT. It consists of five mirrors, with the main mirror having a diameter of 39 meters. The smallest mirror, the M5, is designed to compensate for aberrations and guarantee high image quality, thanks in part to eleven PICA stack actuators from PI Ceramic.

High-Precision ALMA Antennas are Decisive for the Success of the EHT

Sensation in astronomy: The Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes, took the very first image of a black hole, which was published on April 10, 2019. Hexapods developed by PI play an important role in the ALMA telescopes on the Chilean plateau, which are part of the EHT.
