Advanced Optics for Imaging Applications: UV through LWIR VI.
In this paper we present techniques for measuring efficiently the optical properties of chalcogenide glasses. In particular we discuss methods for measuring refractive index and the variation of refractive index with temperature. We then apply these

While widely used in the visible, radial gradient refractive index (GRIN) lenses are still elusive in the IR waveband. In this paper we introduce a new method based on spatially resolved crystallization of chalcogenide glass to produce such lenses. O

Glass-ceramics were fabricated from the 80GeS2⋅20Ga2S3 chalcogenide glass using an appropriate heat-treatment at a fairly low temperature (T g+30°C) for different durations. Compared with the base glass, they present much-improved thermal shock re
