NASA Glenn Research Center is seeking two custom hemi-ellipsoidal mirrors for a specialized optical application.
- **Government buyer:** National Aeronautics and Space Administration (NASA), Glenn Research Center (GRC), under the NASA Shared Services Center; contact named in the attachment: Michael Presby.
- **Products requested:**
- 2 custom nickel, electroformed hemi-ellipsoidal mirrors; no part numbers are specified.
- 1 electroforming mandrel, to be delivered with the mirrors for storage and potential future use.
- **Mirror requirements:** 6.000-inch semi-major axis, 5.916-inch semi-minor axis, 0.1667 eccentricity, and 2-inch focal separation; each mirror has a flange with four mounting holes, 0.040–0.050-inch thickness, and a 1.5-inch through-hole positioned 15° from one focus.
- **Optical requirements:** Concave surface finish of 10 nm or better and surface quality of 80-50 scratch-dig or better. Average reflectivity must exceed 85% at 400–700 nm, 70% at 700–2,000 nm, and 97% at 2–12 μm. Coating composition is flexible if performance is met; reflectivity may be verified using a witness coupon.
- **Notable procurement requirements:** Small-business set-aside; firm-fixed-price procurement evaluated on a lowest-price, technically acceptable basis. Partial quotes are not accepted.
- **OEMs and vendors:** No mirror manufacturer or vendor is named in the notice or attached summaries.
- **Performance period:** Estimated 3–4 months after receipt of the order.
