- Description
- NASA/ARC is hereby issuing a Sources Sought for Infrared Dichroic Beamsplitters for AstroBiology Explorer (ABE). Statement of Work: The vendor shall design and manufacture dichroic beamsplitters according to the specifications outlined below. As part of this procurement, the vendor shall also provide in-house "baseline" performance testing (including cryogenic) to demonstrate that the beamsplitters were made to the outlined specifications. More detailed tests will be performed at NASA Ames. Where applicable, the cost quoted for the beamsplitters should include representative test coupons to be delivered to NASA Ames as part of the procurement. The beamsplitters are to be delivered to NASA Ames on/before October 1, 2004. The vendor shall also provide a delivery schedule for the beamsplitter products, and inform NASA Ames of any modifications to the original procurement schedule. The purchase will be costed as a fixed-cost contract. As part of their bid, the vendor will provide a breakdown of (1) a basic cost quote for Beamsplitter #1 and Beamsplitter #2, quantity 1-each, (2) a delta cost for one additional quantity of each beamsplitter, and (3) detailed costs for any supporting design study, tooling activity, etc. In addition, the vendor shall provide any detailed explanations of exceptions/clarifications if the proposed deliverable cannot meet the specifications. The vendor shall also provide a detailed list of in-house tests to be performed and how these tests will verify performance required. Depending on the cost and performance estimates for the beamsplitters received, NASA Ames will procure one or two beamsplitters from chosen vendor. Specifications: The two AstroBiology Explorer (ABE) beamsplitters are both in collimated space and are part of an infrared cryogenic (T < 20 K) spectrometer. They must separate light into 2.5-5 um, 5-10 um, and 10-20 um) spectral ranges. Although the order of the beamsplitters to split the light is not a static design parameter, the following specifications have been made for the current ABE optical design, shown schematically in a figure available upon request. The end result is to separate 2.5-5 um, 5-10 um, and 10-20 um light with high throughput and no dropouts/gaps between restricted wavelength regions. ABE Beamsplitter #1 Specification This beamsplitter is in collimated space. The specifications below are for a T=20K cryogenic environment. All specifications include dichroic, substrate, and antireflection coating. Reflectance Band: 2.5-5 um Average Reflectance*: > 95% (weighted average over entire band) Minimum Reflectance: 80% Dropouts** allowed: Allowed only between 3.85-4.1 um and 4.8- 5.05 um, provided the 95% spec is met Transmission Band: 5-10 um Average Throughput*: > 80% Minimum Throughput: 80% (worse case over entire band) Transmission Cuton Region/Profile: <= 2% profile (between the 5% and 80% transmission points), rising to > 80% transmission at 5.05 um Location of Cuton Region: Between 4.8 um and 5.05 um (nominal 5 um) Polarization: Maximize throughput* for all polarizations Angle of incidence: Between 44.83 and 45.17 degrees (nominal 45 deg) Diameter: Consistent with a clear aperture "50 mm x 74mm" plus 6- 10 mm mounting clearance Material: Ge Thickness: <= 10 mm (no strong restrictions) Reflected Beam Flatness: 1 fringe over the clear aperture (measured at 632.8 nm) Transmitted Beam Flatness: 1 fringe over the clear aperture (measured at 632.8 nm) Surface Quality: 40-20 (scratch-dig) Environment: Spectral transitions should be optimized for T=20 K environment. Beamsplitters may be cycled from T=20 K through ambient temperature in 10-50% humidity environments. *Average reflectance and transmission requirements to be met for averaged S&P polarization states. **Dropouts have no specified minimum reflectance. ABE Beamsplitter #2 Specification This beamsplitter is in collimated space. The specifications below are for a T=20K cryogenic environment. All specifications include dichroic, substrate, and antireflection coating. Reflectance Band: 2.5-10 um Average Reflectance*: > 95% (weighted average over entire band) Minimum Reflectance: 80% Dropouts allowed**: Allowed only between 3.85-4.1 um, 4.8-5.05 um, and 9.85-10.1 um provided the 95% spec is met Transmission Band: 10-20 um Average Throughput*: > 80% (weighted average over 10-16 um) > 60% (weighted average over 16-20 um) Minimum Throughput: 80% (worse case over 10-16 um) Transmission Cuton Region/Profile: <= 2% profile (between the 5% and 80% transmission points), rising to > 80% transmission at 10.1 um Location of Cuton Region: Between 9.85 and 10.1 um (nominal 10 um) Polarization: Maximize throughput* for all polarizations Angle of incidence: Between 44.83 and 45.17 degrees (nominal 45 deg) Diameter: Consistent with a clear aperture "50 mm x 74mm" plus 6-10 mm mounting clearance Material: ZnSe or CdTe Thickness: <= 10 mm (no strong restrictions) Reflected Beam Flatness: 1 fringe over the clear aperture (measured at 632.8 nm) Transmitted Beam Flatness: 1 fringe over the clear aperture (measured at 632.8 nm) Surface Quality: 40-20 (scratch-dig) Environment: Spectral transitions should be optimized for T=20 K environment. Beamsplitters may be cycled from T=20 K through ambient temperature in 10-50% humidity environments. *Average reflectance and transmission requirements to be met for averaged S&P polarization states. **Dropouts have no specified minimum reflectance. A CAPABILITY PACKAGE MUST BE PROVIDEDED ALONG WITH THE PROPOSAL. This procurement is being conducted under Simplified Acquisition Procedures (SAP). The Government does not intend to acquire a commercial item using FAR Part 12. See note 26. The NAICS Code 333314 and Size Standard 3827 is hereby noted respectively. All responsible sources may submit a response which shall be considered by the agency. An ombudsman has been appointed - See NASA Specific Note "B". The Sources Sought and any documents related to this procurement will be available over the Internet. These documents will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
