Abstract:
Glasses transmitting light up to 20 micrometers have been discovered in the family base on Se and Te. Those out of equilibrium solids are stable enough to be shaped into two kinds of objects: IR lenses and optical fibers. An original molding technique was used to transform the glass into complex lenses with aspheric configuration. These IR optics are used for night vision systems in IR cameras and all kinds of thermal imaging devices. They provide low cost and sustainable heat measurement systems. Taking advantage of the possibilty to control the viscosity of those glasses as a fonction of temperature it is possible to transform these materials into long infared fibers. From this, we have developed sensors based on Fiber Evanescent Wave Spectroscopy. This technique allows the in-situ collection of the IR spectra of molecules. Applications in medecine with the analysis of biological liquid such as humam serum will be presented. Also the analysis of water pollution for environment control wil be described. Four start up companies located close to the campus were born from this research
