Topic: Optimized fused silica used in new astronomical applications
Presenter: Wolfgang Schlichting, Sales Manager Science & Research Optics
Abstract: New astronomical instruments enable scientists to survey the sky in the ultraviolet and near-infrared spectra. The unique optical properties of fused silica, e.g., highest transmission, best homogeneity, and lowest absorption, enable extremely low photon count observations. High-performance fused silica glass overcomes light absorption in the range >800 nm that limits the performance of IR spectrographs. Metallic impurities and OH groups embedded in the fused silica matrix are reduced to achieve best operation. Examples of fused silica optimized for earthbound and spacebound astronomical applications in the NIR and UV are discussed.
In the middle of the Atacama Desert in Chile stands one of the most important facilities for astronomical observations – the Paranal Observatory. The "Very Large Telescope" set up there is the most advanced optical observatory in the world.
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.
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.
