E-MAIL: Maria L. Westman, Maria.L.Westman.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Quotation (RFQ) for 850 ea. optical filters with specifications as follows: the filters must be round, exactly .5 inches in diameter and no thicker than 10mm; E-6 blocking 200-1200nm; refractory oxides; 100 ea. with CWL=340nm, FWHM=2nm; 100 ea. with CWL=440nm, FWHM=10nm; 100 ea. CWL=500nm, FWHM=10nm; 100 ea. CWL=1020nm, FWHM=10nm; 100 ea. CWL=670nm, FWHM=10nm; 150 ea. CWL=870nm, FWHM=10nm; 100 ea. CWL=940nm, FWHM=10nm; 100 ea. CW=380nm, FWHM=2nm. Spectral Band Measurements for all 850 filters are to be provided on disc. The filters must meet exacting optical standards for long term stability under variable temperature and humidity conditions. The filters will be used in the AERONET sun photometers. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GSFC intends to purchase the items from Barr and Associates, Inc., 2 Lyberty Way, Westford, MA 01886. GSFC has had previous success in using Barr Associates ion deposition filters. Their filters can provide and maintain the optical continuity with the past data. The filters have a long term record of measurement. They also provide the long term stability which is of the upmost importance. The data retrieved from the AERONET instruments will be used to validate satellite retrievals of aerosols. Filtered detectors on board satellite systems are provided by Barr Associates indicating a high quality. The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 14 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 14 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
