  STATEMENT OF INTENT: Develop innovative optics that significantly upgrade the future wide-field-of-view (WFOV) capability of Space Based Infrared Systems, an extremely high priority Technology for this PEO
  Objective:  Develop innovative optics, both at the component and system level, that significantly upgrade the future wide-field-of-view (WFOV) capability of Space Based Infrared Systems (SBIRS).
  Description:  A critical technology in SBIRS is the optical system. Future advances in SBIRsSdesire WFOV apertures capable of full-earth viewing with approximately 20-degree full angle. In addition, the optic design must provide an active or passive means for sun exclusion from the sensor plane. System design should include capability for two or more wavelengths, which can be accomplished through splitting the incoming light onto multiple sensors, agile filtering or other innovative means. Systems must also include thermal design and possible coolers. This solicitation seeks innovative advances relevant to WFOV optical designs at the component or system level. Concepts at the component level could include large aperture optics, spectral filters, beam-splitters, baffles and other optical elements. Proposals at the component level should be directed towards the short-wave or mid-wave infrared spectrum or both. Proposals for advances in focal plane arrays, cryocoolers and processing electronics are responsive to this topic only if part of a system solution. Proposals addressing the system level solution can propose to design/develop full infrared (IR) optical payloads or optic benches with multiple critical components. All designs should be flight-like designs, meaning that they are designed with the intent of going through ground environmental testing to advance the system technology readiness level, but not actual flight. For example, a proposal that offers an innovative optical payload may interface to ground non-flight electronics for environmental testing, but it should carry flight-like components and thermal design within the payload. Such decisions in the design trade should be made with the goal of advancing the system-level maturity to the greatest possible extent at reasonable cost. System level payloads designed for “easy” upgrade of their components are responsive and attractive. Upgrades would generally be expected to be accomplished in days, not hours. Proposals can also develop a laboratory test-bed that facilitates rapid testing of other flight components. An optical system that enables rapid evaluation and flight qualification of sensors, optics, processors, thermal components and algorithms is considered highly responsive and attractive. In all cases proposals will be judged on the technology advance they provide for a future geosynchronous earth orbit (GEO) IR spacecraft system.

  PHASE I: Design an innovative IR component or payload. Proposers can propose to deliver prototype hardware or detailed systems designs under Phase I. Proposals will be judged on largest payoff to future WFOV GEO IR systems, risk reduction for a Phase II proposal, and maturity gained in Phase I.
  
  PHASE II: Build, test, and qualify an engineering model of the assembly. Clearly the amount that can be accomplished under Phase II varies significantly between system-level concepts and component technology. In both cases, proposals will be judged on their advancement of technological maturity for space flight.

  DUAL USE COMMERCIALIZATION: Military application: The proposed research and development effort has strong applicability to the Department of Defense (DoD) IR community Commercial application: The technology has strong applicability to the commercial space imagery community.
