Winlight System was in Lyon on September 6, 2013, to attend the celebration of the completion of MUSE instrument. The instrument will be dismounted and shipped to Chili. It will be installed on Atacama desert, on one of the four VLT 8.2 meter telescope of ESO. The French Ministry of Higher Education and Research, Geneviève Fioraso, the scientific community and local and national authorities have acknowledged the work done for over 10 years by the consortium. Winlight System has supplied more than 2500 optical components for the project and many subsystems such as the 24 spectrographs, the 24 image slicers, the derotator, the 48 transport doublets, the field spiltter optics. With this experience, Winlight System has won several calls on projects of similar size.
