Officina Stellare has produced entirely in-house the one meter diameter lenses designed to correct the quality of the focus on the focal plane of the MOONS corrector, the optical and infrared spectrograph intended for Yepun, one of the four 8-meter telescopes of ESO’s Very Large Telescope, installed in Chile.

Moons – Multi-Object Optical and Near-infrared Spectrograph – will collect spectroscopic information from many objects simultaneously, will observe both galactic and extra-galactic stars and objects, working on both the visible light and the near infrared wavelengths. Among its scientific goals, there will also be the study of the chemical composition of exoplanets atmospheres.
