New refractive index data on GLS glass now available

GLS refractive index

GLS refractive index vs. wavelength

We have recently obtained new infrared ellipsometry data for our Gallium Lanthium Sulphide glass giving more accurate refractive index measurements to 10um. If you would like more detailed n or k data in this spectral region please contact us. The latest data sheet also has updates on the physical and optical propoerties of GLS Chalcogenide glass.

Glass purity – reducing loss, extending operation, enabling applications

GLS_loss_LD1625_8-12um_2015A key focus of Champ is to continue the work conducted under the EPSRC Centre for Innovative Manufacturing in Photonics on reducing contamination and impurities in Chalcogenide glass.  A long-term focus on purifying raw materials and optimising the manufacturing process has led to a signficant reduction in oxide and water impurities.  GLS Chalcogenide glass loss in 2-6 micron windowThis has  yielded a 100x fold reduction in transmission loss at 5um and a signficant extension of the operating band edge to >10.5um, as shown, removing the path to applying chalcogenides in many applications.

Note there is no offset applied in these loss figures– the curve shown are a true reflection of the glass loss and the improvements made.
