This is a technical specification document for optical lens components, specifically doublets, dated 12/15/2025. The specification details three lens designs with precise dimensional and material requirements. The first lens features a radius of 126.472 CX millimeters with an edge diameter of 16.000 mm and S-LAL8 material composition, 9.940 mm thickness, with a tolerance of +/-0.05 mm. The second lens has a radius of 17.496 mm with identical edge diameter and material specifications but reduced thickness of 5.170 mm. The third lens specifies a radius of 24.292 CX mm with N-FK51A material and the same edge diameter specifications. All three lenses share a center aperture diameter of 14.4 mm. The document mandates manufacturing compliance with MIL-G-174B standards and MIL-PRF-13830B specifications, requiring pitch polish to test plate with specified radius tolerances of +/-0.1% or 3 feet, and irregularity limits of 0.25 waves PV. Additional requirements include anti-reflective coating on both sides with reflectance less than 0.5% across 350-800 nm wavelengths, 60-40 scratch-dig surface finish, surface roughness under 10 Angstrom RMS, and optional bevel specifications of 0.3-0.5 mm by 45 degrees. The document is presented at 3:1 scale with a width specification of 6.67 mm.
