99 -- METERING STRUCTURE SOL RFQ BF3006 DUE 043099 POC Point of Contract: Elizabeth Ciampaglia, 617/495-7402, FAX 617/496-7992, email: eciampaglia@cfa.harvard.edu, Contracting Officer: Peter W. Sozanski, 617/495-7376 The Smithsonian Astrophysical Observatory (SAO) requires the fabrication of a large Zerodur metering structure to fixture two echelle gratings in the Hectochelle spectrograph for the converted MMT telescope. The finished dimensions of the metering structure will be 34.7 inches by 16.2 inches by 12.2 inches. The structure will be built by bonding four (4) pieces of Zerodur, to be supplied by SAO. The thickness of all bond lines must be extremely precise, i.e. 0.004 inches +/- 0.0015 inches, although this tolerance may be revised slightly, depending on what adhesive is selected for the bonds. The Zerodur will be supplied with a tolerance of +0.1/-0.0 of the finish dimension, so proposer must grind the Zerodur to finish dimension with sufficient precision to meet the bond thickness specification. All unbonded surfaces must be ground to 400 grit finish or better. In addition, there are numerous details -- i.e. holes and grooves -- that must be machined into the metering structure so that we may fixture the gratings accurately and stably. Anticipated award date is 30 April 1999. This metering structure is to be delivered FOB Destination to SAO five (5) months ARO. Only written, fax (FAX 617/496-7992), or email (eciampaglia@cfa.harvard.edu) requests received directly from the requestor are acceptable. All responsible sources may submit an offer. No telephone requests for the solicitation package will be accepted. This acquisition is being conducted under the guidelines set forth in FAR, Part 13, Simplified Acquisition Procedures.
