Optical Integrating Sphere Supply

The contract entails the supply of two 4-inch integrating spheres specifically designed for light measurement applications at a wavelength of 780 nm, intended for use in precision optical testing and calibration environments. These devices are critical for accurately measuring radiant flux and light distribution in controlled conditions, and their specification ensures compatibility with infrared and near-infrared optical systems commonly utilized in defense and aerospace applications. The requirement is issued under a subcontract arrangement by the Department of Defense through its W6QK Acc-Rsa office, with performance to be carried out at Redstone Arsenal, Alabama, 35898. The solicitation was posted on June 30, 2026, with a firm deadline for responses set for July 16, 2026, at 9:00 PM Eastern Time. This procurement falls under NAICS code 334516, which designates the manufacturing of instruments and controls for measuring and testing light and radiation, indicating that suppliers must possess specialized expertise in optical hardware fabrication and calibration. Although no set-aside provisions or point of contact details are provided, the place of performance and agency affiliation suggest the end-use is tied to military or defense-related research activities requiring high-reliability optical components.
