Additive Manufacture of Thermal Infrared Optics

??????? The proposed effort aims to develop a technology platform that can deposit non-toxic infrared optical materials on existing substrates to refurbish MWIR and LWIR optical components. The challenge lies in matching the refractive index, dispersion, and partial-dispersion properties of the existing lens or optical substrate, which requires precise deposition of custom optical feedstock composed of precursors, nanoparticles, binders, and solvents. The project focuses on developing hybrid nanocomposite materials based on inorganic nanoparticle-loaded nanocomposites.ĀĀ The aim is to demonstrate the ability to identify and manufacture a set of nanocomposite feedstock with a range of refractive index and dispersion values, and the rheological properties that allow for efficient inkjet print deposition.Ā The program will also begin to develop an insitu drying and densification process.ĀĀĀ The project will test the properties of MWIR and LWIR glasses, specifically their optical and mechanical characteristics, and analyze the yield and develop a cost model for producing the expected quantity levels. The technology platform will enable the refurbishing of existing MWIR and LWIR optical components, reducing waste and saving costs.
