Sulfur-based polymer material with IR transmission from ~700 to 6200nm for low cost lightweight IR solutions.

摘要

Brimstone Holding, a partner of Semper Fi Systems, is the first company to synthesize sulfur-based polymers with infrared transmission at a wavelength from ~700 to 6200 nm that lack chemical groups absorbing in the near-IR region. This range can be extended or narrowed if needed by using different monomers and oligomers and by variation of elemental sulfur content. In addition, this material shows possible utility as an optical adhesive as it strongly attaches to everything except silicone. Our proprietary polymer material can be produced sustainably and inexpensively in large scale without requiring the use of rare and expensive semiconductor crystals or highly toxic chalcogenide glass manufacturing. The Brimstone Lens™ material can be molded with ease into complex shapes, curvatures and sizes and is amenable to grinding and polishing. The Brimstone Lens™ polymer can serve as a base for complex IR nanostructures with previously unattainable properties. Our low cost Brimstone Lens™ will allow for numerous inexpensive applications in security and guidance systems, quality analyzers, infrared cameras, night vision goggles and optics, automotive safety, as well as in the production of solar panels and electric battery cells, along with numerous other potential uses, without diminishing the quality of an IR solution. The replacement of Germanium would minimize US dependency on China's mining and distribution of these expensive and rare metals.
