Fabrication of Lens Mount Assemblies for Binospec Spectrograh

The Smithsonian Astrophysical Observatory (SAO) requires the fabrication and delivery of two (2) lens mount assemblies (SN1 and SN2) for the Binospec spectrograph to be used at the MMT Observatory. Each assembly will contain a total of nine (9) bezels that support the various collimator lenses. The bezel diameters range between 12 inches to 15 inches in diameter and weigh between 3 to 9 lbs each. The housings that support the bezels are ~15 inches by 17 inches. The total dimensions for each lens mount assembly are 17 inches by 28 inches and weigh ~72 lbs. The bezels are all made from 7050-T7451 aluminum and incorporate an integral flexure design that requires electron discharge machining (EDM) capability. The support housings are made from 6061-T6 aluminum. Several other materials such as titanium, Kovar, Invar and steel are used for the bezel nubs. There are several precision machined surfaces as well as mechanical alignment tolerances that are held to .0005 inches. Proposals are to be prepared in accordance with the attached Instructions. A firm-fixed price contract for this procurement is contemplated. Offers will be evaluated on (1) Evidence of technical expertise and infrastructure to fabricate and test large optical mounts of this type at a level deemed sufficient by SAO; (2) Offeror's prior experience and past performance with items of comparable complexity, size, tolerances and materials; (3) total price to the Government; and (4) delivery schedule. The firm date for receipt of proposals is 28 August 2009 at 5:00 PM (EDT). The anticipated award date is on or about 18 September 2009. The anticipated delivery date for the two (2) assemblies will be TBD after receipt of award of the contract. Delivery is F.O.B. Destination, Cambridge, Massachusetts.
