Fluoride Glass Fibers

Our products

Le Verre Fluoré provides the most transparent mid-infrared fibers of the market.

Le Verre Fluoré

Le Verre Fluoré was established in 1977 as a spin-off of the discovery of fluoride glasses by Poulain brothers.

40 years of continuous R&D effort led to outstanding pionneering achievements.

Among them, ZBLAN and Fluoroindate glasses, low loss mid-infrared fibers, qualified for industrial use. High reliability and low costs outline the maturity of our fluoride glass technology.

The company added recently a new range of Germanate multimode fibers for surgery and dentistry applications (Er:YAG laser and Er,Cr:YSGG laser beam delivery) in its product portfolio.


Fluoride glass technology allows very efficient transmission and laser emission in mid-infrared.

Germanate fibers are the fibers of choice for surgery and dentistry applications (Er:YAG laser and Er,Cr:YSGG laser beam delivery)

Fluoride glass is a key technology for many mid-infrared industrial applications.

Our multimode fibers are the fibers of choice to transmit  light in process and measurement involving mid-infrared spectroscopy/analysis

Since 1987, LVF is the reference company for astronomy developments

Thanks to its outstanding properties, fluoride glass allows innovative laser developments from UV to mid-infrared

Fluoride glass technology allows also the development of Praseodymium and Thulium doped fibers for amplifiers in O and S bands.
