Homogeneous and Gradient Index (GRIN) Materials For Multi-Band IR Optics

We report new materials for multi-spectral infrared (IR) optics including IR gradient index (IR-GRIN) materials with a delta-n of 0.1 and new homogeneous glasses. These new materials transmit SWIR-LWIR (0.9 μm - >12 μm) and fill gaps in the IR materials dispersion map.
