About this file
This is a Statement of Work for the manufacture of quantity two (2) hemi-ellipsoidal mirrors for NASA Glenn Research Center. The mirrors shall be manufactured via electroforming using a nickel substrate with the following specifications: semi-major axis of 6.000 inches, semi-minor axis of 5.916 inches, ellipse eccentricity of 0.1667, and 2-inch focal separation. Each mirror must have an acceptable thickness of 0.040–0.050 inches, include a flange with four thru holes for mounting, and feature a 1.5-inch diameter thru hole aligned 15° from one focal point. The concave surface requires a surface finish of 10nm or better, surface quality of 80-50 (scratch-dig) or better, and a reflective coating meeting the following spectral requirements: average reflection greater than 85% from 400–700 nm, greater than 70% from 700–2,000 nm, and greater than 97% from 2–12 µm. Reflectivity may be verified on a witness coupon, and coating composition is flexible provided specifications are met.
Delivery shall be made to NASA Glenn Research Center, Attn: Michael Presby, 21000 Brookpark Rd, Bldg. 106 Rm. 108, Cleveland, OH 44135. The electroforming mandrel used in production must be delivered along with the two mirrors for storage and future use. The estimated period of performance is 3–4 months after receiving the order. Technical drawings and detailed dimensional specifications are provided on the attached engineering diagram.

Statement of Work
This statement of work provides the requirements for quantity two (2) hemi-ellipsoidal mirrors.
The exact geometry and dimensions required for the mirror are provided on the next page.
The hemi-ellipsoidal mirror has a semi-major axis of 6.000 inches and a semi-minor axis 5.916 inches. This yields an ellipse eccentricity of 0.1667 and a 2 inch separation of the foci.
The mirror shall be manufactured via electroforming.
The mirror substrate shall be Nickel (Ni).
The mirror shall have a flange with four thru holes for mounting purposes.
Acceptable mirror thickness is 0.040 – 0.050’’.
The mirror shall have 1.5 inch diameter thru hole aligned 15° from the one focal point.
The inside (concave) surface of the mirror shall have:
o Surface finish of 10nm or better o Surface quality of 80-50 (scratch-dig) or better o Coated with a reflective coating to the following specifications:
Average reflection > 85% from 400 – 700 nm spectral range Average reflection > 70% from 700 – 2,000 nm spectral range Average reflection > 97% from 2 – 12 µm spectral range Note: the reflectivity can be measured / verified on a witness coupon.
Note: Exact coating composition is flexible as long as it meets the above requirements.
The mandrel used for electroforming shall be delivered along with the two mirrors for storage and future use if needed.
Delivery will be to
NASA Glenn Research Center Attn: Michael Presby 21000 Brookpark Rd Bldg. 106 Rm. 108 Cleveland, OH 44135
Estimated period of performance is 3-4 months after receiving order.
