About this file
The file contains a detailed technical specification for Government Furnished Equipment (GFE) involving five uncoated Corning 7980 glass wedges with precise optical requirements. The specification outlines two distinct surface specifications: Surface-1 remains uncoated with a clear aperture of 11.34, wavefront distortion of λ/20 PV at 632 nm, and a scratch-dig rating of 20/10, while Surface-2 requires a custom Optimax coating with a clear aperture of 11.34, wavefront distortion of 5λ PV at 632 nm, and an 80/60 rear surface finish.
The related federal contract opportunity is a sole-source solicitation (N0017825Q6753) issued by the Department of the Navy Naval Sea Systems Command, targeting Optimax Systems, Inc. for specialized optical coating products. The solicitation is a Request for Quotation (RFQ) for commercial items, with quotes due by May 7, 2025, and an anticipated award date of June 15, 2025. The contract will be awarded on a Lowest Price Technically Acceptable basis, using Simplified Acquisition Procedures, and requires TAA compliance. The specific coatings are critical for megawatt class laser system testing, with no alternative suppliers identified due to the unique technical requirements.
