Status des brevets
French patent
application FR1351795
filed on February 28th,
2013 entitled "Verres et
vitrocéramiques
nanostructurés
transparents dans le
visible et l’infrarouge"
Materials which are transparent in Infrared wavelength at 6µm are important for optical
applications. In particular, glass and ceramic glass are interesting compared to crystals as
they could be manufactured in large size.
TECHNICAL DESCRIPTION
The invention is related to a new family of glass and ceramic glass, their manufacturing
process and their application in optical applications.
