Chalcogenide Glasses Summary

Chalcogenide glasses have an excellent transmittance and a low thermal change in refractive index and dispersion. This makes it easier for you to design color corrected, infrared optical systems without thermal defocusing in the 1-14 µm spectrum. Our glasses are also ideal for applications in combination with other IR materials.

Classic or single-grained diamond processing as well as final pressing enable you to use these as , with spherically and/or aspherically shaped surfaces, and other optical components.

We produce 5 different kinds of chalcogenide glasses for you:

IG2 - Ge33∙As12∙Se55 IG3 - Ge30∙As13∙Se32∙Te25 IG4 - Ge10∙As40∙Se50 IG5 - Ge28∙Sb12∙Se60
