Optimisation of material composition for individual applications is a core part of ChAMP. This is achieved through partnership with the Advanced Composite Materials Facility (ACMF) at the University of Southampton headed by Prof. Brian Hayden and housed in the department of Chemistry. …
The enhanced infrared performance of a new modified Gallium Lanthium Sulphide (GLS) chalcogenide glass family is illustrated in this transmission curve. Details of the modification and the range transmission achieved are in Dan Hewak’s latest presentation. The strong bonding and high glass transition temperature that characterise GLS glasses are maintained in this formulation and are…
Building on ChAMP, the Optoelectronics Research Centre (ORC) and Plasma App Ltd are collaborating in a one-year £150k feasibility study exploring novel thin film coating technology and applications for Gallium Lanthanum Sulphide (GLS) Chalcogenide glass
…
With a new glass formulation, ChAMP has extended the transmission of high durability non-toxic chalcogenide glasses from the visible to the thermal infrared LWIR band Images show a thermal LWIR image from 7-14 microns being simultaneously transmitted through the same glass as the visible image. With a glass formulation specifically chosen for its strong covalent…
In operation at SPIE Security + Defence and Remote Sensing meeting in Edinburgh 27-28 September 2016
Prof Dan Hewak, presented the latest ground breaking developments on chalcogenide glasses developed in ChAMP on Wednesday 28 September 2016 at SPIE Security + Defence and Remote Sensing meeting in Edinburgh. 17:10 paper 9989-2 Dan’s full presentation on next generation chalcogenide glasses is available here including details of the new extended GLS glass with transmission…
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…
As part of the Glass Reflections Conference ChAMP are orgainising a one day workshop on Chalcogenides on 9 September 2015 at Murray Edwards College, University of Cambridge.
To attend please register with the day rate for the Chalcogenide workshop or you are also of course welcome to attend the entire conference, which runs from 7 – 9 Sept
Papers include:-
…
Computers that function like the human brain, using optical fibres made of chalcogenide glass, could become a reality according to new research.

A 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. This has yielded a…
