Optical filter/ specified etalon

NASA’s National Security Space Center seeks two high‑precision solid etalon optical filters (specified etalons) to be supplied and delivered to Langley Research Center. The requirement includes fused‑silica bodies, precise coating, bonding with Norland 61, and potential post‑delivery polishing to meet strict wavelength tolerances. The contract will be a sole‑source award to LightMachinery Inc, but capability statements are being collected to evaluate competition. Delivery is expected within two months after order release. • Quantity: 2 solid etalon assemblies meeting detailed optical, mechanical, and thermal specs. • Technical scope: coating, bonding, possible polishing, and compliance with free spectral range, FWHM, center wavelength, transmission, and field‑of‑view requirements. • Performance timeline: 2‑month period of performance after order release; submission of capability statements due 4 p.m. CST on 10/08/2026.
