PICA Stack Actuators from PI for Precise and Reliable Image Stabilization in the World’s Largest Telescope
· Dr. Daniel Jakobsen
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.
Hybrid drives combine two different drive concepts into a high-performance and precision positioning system. Nanopositioning systems that combine piezo drives with classical drive screws therefore offer a practical solution, but also other drive concepts are possible.
The starlit sky has been fascinating humanity since the dawn of time. Observing distant galaxies, discovering new planetary systems and the idea of life outside our solar system does not only inspire our fantasy but also provides us with important insights for a better understanding of the universe.
