GLS-Se extruded optical fibre

Extruding chalcogenide glass for optical fibre

Core-clad GLS-Se optical fibre
Core-clad GLS-Se optical fibre from extruded preform*

ChAMP has demonstrated for the first time fabrication of a core-clad GLS-Se glass-based optical fibre using extrusion. For initial demonstration two glass compositions similar in thermal and mechanical characteristics were chosen, with only a 5wt% difference of Ga2Se3 between core and cladding. Billets of 30mm in diameter and different thicknesses were fabricated using established and repeatable melt quenching process in our facilities

Sellmeier Coefficients for GLS glass


In response to many requests from optical designers and using the latest visible to infrared index data for GLS glass we are pleased to release the full Sellmeier coefficients for GLS. Use of the following coefficient enables the refractive properties of GLS lenses to be modelled in most common lens design programs.
