commercial status

Exclusive or non-exclusive licenses, Collaborative agreement

Laboratory

Laboratoire Conditions Extrêmes et Matériaux Haute Température et Irradiation (CEMHTI), a CNRS laboratory (UPR 3079) in Orléans, France.

Description

CONTEXT

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.

BENEFITS

Materials are transparent from visible to far infrared (until 6µm) and could be easily manufactured in large size.
In addition, doping with rare earth elements is feasible allowing laser applications. 

INDUSTRIAL APPLICATIONS

The main application of this invention are:

  • Optics
  • Medical imaging
  • Lighting
  • Display

DEVELOPMENT STAGE

Synthesis and characterization are made at a laboratory scale. Glass and ceramic glass samples were made in a range between 1 to 20 g.
Temperature synthesis are in the range of typical glass process (less than 1300°C).
