E-MAIL: Maria L. Westman, Maria.L.Westman.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Quote (RFQ) for two (2) each temperature tunable single solid cleartran (ZNS) etalons and two (2) each temperature tunable single clearceram etalons. All etalon types shall meet the following specifications: usable clear aperture: 35mm; center wavelength (normal incidence): 532.213NM +/-0.005NM (vacuum wavelength); free spectral range: >400PM; transmission at center wavelength (when illuminated with a 35mm diameter collimated beam): >90%; etalon mount maximum diameter: 60mm. Specifications specific for the cleartran etalon: FWHM bandwidth: 25PM +/-3PM; indium tin oxide coating; center wavelength at 35 degrees Celcius. Specifications specific for the clearceram etalon: FWHM bandwidth: 25PM +/-3PM; indium tin oxide coating; center wavelength at 35 degrees Celcius. A tunable narrow band etalon optical filter is required for the aerosol lidar receiver of the Geoscience Laser Altimeter System (GLAS) instrument on the Ice and Cloud Elevation Satellite (ICESAT) of the Earth Observing System (EOS). The etalon filter must be manufactured such that the center wavelength matches the GLAS laser wavelength at the required temperatures (as listed in the specifications). The etalon should not require a capacitive sensor but mechanical engineering and rugged construction to insure the etalon parallelism and controlled gap spacing is maintained. The etalon must be low weight (less than 600 grams) and rugged (meet MIL-STD-883, method 2007, Condition A) to meet the space flight and 3 year life time requirements of the GLAS mission. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). The Government intends to acquire a commercial item using FAR PART 12. This procurement is a total small business set-aside. See Note 1. The SIC Code and Size Standard are 3829 and 500 employees. The DPAS Rating for this procurement is DOC9. The anticipated release date of RFQ924-74402-921 is on or about 05/06/1998 with an anticipated quote due date of on or about 05/25/1998. A copy of the RFQ package shall be requested in writing. All qualified responsible sources may submit a quote which shall be considered by the agency. An ombudsman has been appointed -- See Internet Note "B".
