Glass production by using Melt-Quenching process :  Thanks to a lift furnace (Max Temperature around 1700°C), we can produce silica glasses (up to 70% of silica in the final composition). Planetary Milling Unit helps us to produce dedicated granulometry. Purification of material powders (O2 / He / C2F6 / N2 / Ar @ 1800°C)Some Projects [...]

We have developed skills and equipments around glass working, and principaly for silica material. Burners associated with a glass lathe for tube assembling, home made diamond cutting system, polishing machine are some of the important equipments available.     Videos available : 1. Machining of a powder rod fabricated with 1500 bars pression : https://mediaserver.unilim.fr/permalink/v12689cd54bc62jlrjj6/ [...]

Following Glass synthesis (in powder way), materials have to be treated and shapd in order to produce a transparent rod, used at least to realiser the optical preform. A first stage consists to purify with gas (O2, C2F6) at high temperature (up to 900°C) these materials. The second is to produce a compact powder rod, [...]

Some Equipments are dedicated to characterisation of material such as Tornado M4 (Brukker) to quantify elements present in glass realisations.                     On the right picture, a RIP of a Panda fibre. We have also access to the stress in the fibre.     An LZM CO2 [...]
