♦ Covestro cooperates with the Italian Institute of Astrophysics

♦ Enhance the performance of astronomical instruments with holographic optics

♦ Tailored photopolymer films for multiple uses

Today's astronomical high-performance telescopes can not only perform precise imaging observations of stars and galaxies, but also perform a large number of highly specialized physical studies to elucidate the physical and chemical processes of stars from formation to supernovae

The Italian National Institute for Astrophysics (INAF) is working on holographic optics based on volume holograms, which can be very efficient at splitting light from stars into different colors for spectroscopic studies

The new "Stars at your fingertips"

"Because of these photopolymer films that can contain light, we are really able to push the boundaries of astronomical observations," said Alessio Zanutta, project manager for holography at INAF at Brera Observatory, "compared to the materials previously used to make diffraction gratings and their processing limitations.
, Bayfol® HX volume holograms enable a wide variety of diffraction grating geometries with a high degree of combinatoriality, or integration with other optical components

The Bayfol® HX film consists of a transparent carrier film on which is placed a photosensitive layer and an additional protective outer film

Wide range of applications

"Our photopolymer films can be successfully used in demanding applications, such as spectrometers in high-performance telescopes for astronomy
