Transmission of extended transmission GLS

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…

Latest ChAMP glass demonstrates extended IR transmission

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…

Lastest Chalcogenide Glass developments

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…

New refractive index data on GLS glass now available

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…
