Aluminum Off-Axis Parabola Mirrors for Lunar Lidar Prototype

Summary (Newest Update)

Background The National Aeronautics and Space Administration (NASA) is issuing this Request for Quotation (RFQ) for the procurement of Aluminum Off-Axis Parabola Mirrors intended for a Lunar Lidar Prototype. This project aims to develop a swath-mapping space lidar prototype that operates at a wavelength of 1550 nm, which is crucial for advancing NASA's mission in space exploration and technology development. The procurement is specifically set aside for small businesses. Work Details The contractor is required to provide the following high-precision gold-plated mirrors as part of the transmitter optics subsystem: 1. **Transmitter Mirror 3** - Mirror Substrate: Aluminum RSA-6061 - Diameter: 66 mm - Clear Aperture: 64 mm - Surface 1: CONCAVE ROC = 313.851 ± 0.1 MM, CONIC COEFFICIENT (K) = -1, VERTEX OFFSET DISTANCE TO MECHANICAL AXIS = 135.269 MM - Surface 1: RMS surface figure irregularity < 55 NM - Surface 1: Polished to 40 Å RMS surface roughness or better - Surface 1: Enhanced Gold coating with dielectric coating between λ = 1520 -1580 nm, Reflectance no lower than 95% in the same waveband - Chamfers on inner and outer edges: 0.25 - 0.5 MM, 45 degrees - Surfaces 2/3/4: PLANER, polished to 75 Å RMS surface roughness or better - Protective coating required for Surfaces 2, 3, and 4 - Scratch/Dig specifications: 40/20 for Surface 1; 60/40 for Surfaces 2, 3, and 4 - Finish: Black Anodized (except surfaces 1, 2, 3, and 4) - Quantity needed: **2** 2. **Transmitter Mirror 4** - Mirror Substrate: Aluminum RSA-6061 - Diameter: 25.4 mm - Clear Aperture: 23 mm - Surface 1: CONCAVE ROC = 104.617 ± 0.1 MM, CONIC COEFFICIENT (K) = -1, VERTEX OFFSET DISTANCE TO MECHANICAL AXIS = 45.088 MM - Surface 1: RMS surface figure irregularity < 55 NM - Surface 1: Polished to 40 Å RMS surface roughness or better - Surface 1: Enhanced Gold coating with dielectric coating between λ = 1520 -1580 nm, Reflectance no lower than 95% in the same waveband - Chamfers on inner and outer edges: **0.25 - 0.5 MM**, **45 degrees** - Surfaces need protective coating as specified. - Scratch/Dig specifications similar to Transmitter Mirror 3. - Finish and quantity requirements are consistent with those outlined above. Period of Performance The period of performance for this contract extends until May 12,2026. Place of Performance The work will be performed at Stennis Space Center located in Mississippi.
