- Description
- The Smithsonian Astrophysical Observatory (SAO) requires the fabrication, coating, test, and delivery of six (6) large aspheric lenses, designated Collimator Lens 1, Collimator Lens 8, and Camera Lens 1, for the Binospec program. Binospec is a binocular optical spectrograph that uses a refractive collimator to form a ~200 mm pupil on a diffraction grating, and a refractive camera to image the dispersed light onto a CCD imaging array. Each of Binospec's identical channels contains 19 lenses, for a total of 38. The collimator contains nine lenses in three groups, and the camera contains ten lenses in four groups. Two of the collimator lenses and one of the camera lenses carry aspheric surfaces with 4th, 6th and 8th order terms added to a base (spherical) surface. SAO needs to procure a total of six aspheric lenses. Only one surface of each lens is aspheric; the facing surface is polished to a sphere. The Aspheric Departures for the lenses is 0.5 mm. SAO wishes to purchase completed lenses with both surfaces polished to our specifications, with a broad band antireflection coating applied to the aspheric surfaces. Collimator Lens 1 is made from Ohara Glass Type BAL 15Y and has a diameter of 316 mm, a spherical radius of curvature of 209 mm, an edge thickness of 53 mm, and a center thickness of 15 mm. Collimator Lens 8 is made from Ohara Glass Type BSM 51Y and has a diameter of 286 mm, a spherical radius of curvature of 2,223 mm, an edge thickness of 25 mm, and a center thickness of 17 mm. Camera Lens 1 is made from Ohara Glass Type BAL 35Y and has a diameter of 358 mm, a spherical radius of curvature of 260 mm, an edge thickness of 49 mm, and a center thickness of 15 mm. SAO will provide the lens blanks. Scratch/Dig is 60/40. Surface Finish is better than 30 Angstroms RMS. We expect that each aspheric lens will be tested in transmission, using a spherical reference and a holographic null lens, supplemented by surface roughness measurements. In addition, we prefer that profilometer scans be made of the aspherical surfaces to independently verify that the specified aspheric shape is achieved. For Surface Figure, the single-pass wavefront deviation from nominal shall be less than 0.05 waves RMS (reference wavelength 6328 Angstroms) over the entire clear aperture. On scales of 1 mm and less, the surface roughness shall be less than 20 Angstroms RMS. On any scale up the full lens aperture, the RMS slope errors shall be less than 5x10-6 radians. Prospective vendors shall specify how these surface roughness and slope error measurements will be made. A firm-fixed price contract for this procurement is contemplated. Offers will be evaluated on price, technical proposal, past performance, and ability to meet the schedule. The anticipated release date of the RFP is on or about 1 April 2004 with an anticipated proposal due date on or about 1 May 2004. The firm date for receipt of proposals will be stated in the RFP. The anticipated award date is on or about 1 June 2004. The anticipated delivery date for the six lenses will be twelve months after award of the contract. Delivery is f.o.b. destination, Cambridge, Massachusetts. Only written, fax, or email requests for a solicitation received directly from the requester are acceptable. No telephone requests for the solicitation will be accepted. The North American Industry Classification System (NAICS) Code and size standard are 333314 and 500 Employees, respectively. All qualified responsible sources may submit an offer, which will be considered by the agency. This procurement will be conducted using the methods described in the Federal Acquisition Regulation (FAR) Subpart 12.6, Streamlined Procedures for Evaluation and Solicitation for Commercial Items.
