Novel Long-Wave Infrared Transparent Thermoset Polymers for Optical Components and Imaging Systems
This invention is new polymeric materials with improved Long Wave Infrared (LWIR) transmission as demonstrated by IR spectroscopy and IR thermal imaging. A one mm thick polymer film demonstrated transmittance with an LWIR camera in the 7.5-13 micron regime. The polymer is a thermoset and can be fabricated into windows, lenses, and prisms using simple...

Photoresponsive Polymer Films for Photo-Patterned Waveguides
University of Arizona researchers have developed a new class of high refractive index polymers that can be deposited as thin films and directly photo-patterned into useful device architectures. The resulting cured (e.g. photo-exposed) regions have a reduced refractive index, which is 0.01-0.05 lower than the unexposed regions and, hence, have tremendous...
