Survivable & Affordable Lens Technology (SALT)

The Department of Defense, through the Office of the Secretary of Defense SBIR program, is seeking proposals to investigate the viability of using low-cost alkali-halide optical materials as alternatives to traditional, expensive military-grade infrared optics for attritable unmanned drone vehicles. Phase I requires optical design exercises, high-volume manufacturability analysis, shelf-life projections, and costing comparisons, while Phase II involves manufacturing hardware demonstration units, implementing passive athermalization, and validating moisture-resistant coatings. The primary technical focus is on applying these materials to uncooled thermal infrared sensors, such as the Odd Systems Kurbas-640, while ensuring the lens assemblies can withstand moisture and water damage per military standards. Proposals must be submitted between July 22, 2026, and the closing deadline of August 19, 2026.
