Chalcogenide Glasses Specifications
Infrared transmissive chalcogenide glass
VITRON Spezialwerkstoffe GmbH – IG-glasses are made of the components Ge-As-Se-Sb-Te. Its excellent transmission, low thermal change in refractive index and its dispersion makes it easier for optical designers to develop color corrected IR optical systems free from thermal defocusing. It is also ideal in combination with other infrared materials.
We offer you our IG glasses according to your wishes: as cut blanks, milled and moldings for your own optics machining, or as a finished optic with or without antireflection coating for both atmospheric 3-5 µm
and 8-12 µm.
