PLATO - Planetary transits and oscillations of stars

About the project

This space telescope is currently under development by ESA and scheduled to launch in 2026. PLATO will search for planetary transits across up to one million stars to discover and characterize earth-like extrasolar planets in the habitable zone around sun-like stars. Another objective is to study stellar oscillations or seismic activity in stars to measure their masses, age, and evolution. The mission is designed to observe significantly more stars with greater precision of the measurements. This data will be further enhanced by post-detection investigations such as spectroscopy, asteroseismology, and in some cases imaging. With this method the observation can be expanded to small exoplanets and exoplanets with long orbital periods.

Our contribution

Visual/NIR light cameras wide-field telescopes for measurement 500-1000 nm, need to be protected. The optics are exposed to a radiation hard environment. To protect the sensitive infra-red imaging optics and electronics in the harsh radiation environment in space, Heraeus Conamic supports the PLATO mission with radiation hardened  Suprasil 312 high-purity fused silica windows from damage due to solar protons.
