Integration of the Eclipse Transparent Electrical Conductor and Eclipse Multiline Rejection Filter Technology for Transparent Armor Applications Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-014 Topic Title: Integration of the Eclipse Transparent Electrical Conductor and Eclipse Multiline Rejection Filter Technology for Transparent Armor Applications Proposal No.: N091-014-1531 Firm: Eclipse Energy Systems, Inc. 2345 Anvil Street North St. Petersburg, Florida 33710-3905 Contact: Rand Dannenberg Phone: (727) 344-7300 Web Site: eclipsethinfilms.com Abstract: As optical systems increase in their sensitivity and sensors become more capable, modern and future rotary wing aircraft will suffer from the need to have transparent armor systems that are transparent in the visible wavelengths and sensor wavelengths of interest while incorporating low ohm coatings for shielding efficiency as well as filters to protect against laser threats. The challenge is in providing a system that increases crew protection by the reduction of laser threats, and solar loading on transparent armor while enhancing the shielding efficiency and not reducing the mission capabilities by limiting transmission in wavelengths of interest. Eclipse Energy Systems, Inc. has addressed these current and future needs with the Eclipse Transparent Electrical Conductor (TEC) and Advanced Filter Technologies such as Rugate filter systems. The EclipseTECT is a flexible visually transparent electrical conductor (88%+ transmission at 550 nm, <5 ohms/ sheet resistance). In this proposal, Eclipse will utilize the expertise and infrastructure capabilities to fabricate a conductive coating and a narrow band blocking filter on an acrylic aircraft window. This window will be tested to demonstrate a reduction in radar cross section and characterized to measure the blocking capabilities of the coating. Benefits: The transparent conducting coatings developed in the present program will have applications in flat panel and flexible displays, anti-static devices and EMI/RFI Shielding, passive solar control coating, electrochromic and variable emissivity devices, electro-optical and instrument systems, solar photovoltaics and transparent electronics.
