Infrared Freeform Gradient Index Optics

Freeform gradient refractive index (GRIN) glass lenses for use at infrared (IR) wavelengths between 2 micro;m and 40 micro;m will be developed for use in high-performance infrared science missions. Designs will includine phase-dispersive and phase-correcting elements. To demonstrate the perforamnce, size, and weight benefits of freeform gradient-index infrared optics, inorganic infrared optical feedstock will be developed and characterized. The properties of gradient-index optics fabricated using additive-manufacturing processes will be measured and characterized. The measured optical properties will be used to update existing modeling and simulation tools, and the performance, size, weight, cost, and schedule impact of the technology will be quantified in candidate telescope designs. nbsp;
