66 -- BUILD AN INFRA-RED INTERFEROMETER FOR WINDOW THICKNESS SOL 52SBNB6C9246 DUE 091396 POC Linda Shariati (301) 975-5053 The National Institute of Standards and Technology (NIST) intends to build an infra-red interferometer for window thickness. The Precision Machining Research Facility at NIST has built a bench-top demonstration interferometer and developed associated measurement protocols which allows for measurement of thickness, thickness variation, and bow of windows. Using anappropriate laser, these measurements can be made on materials of interest to the optics, IC and other industries and, at appropriate wavelengths, does not require that both surfaces be polished. The Contractor shall build a phase shifting prototype instrument capable of measuring windows (wafers) up to 300 mm diameter. The Contractor shall provide key personnel for this acquisition. This acquisition is being conducted in three phases. This Commerce Business Daily announcement constitutes Phase I. Phase I is a request for all interested parties to submit information which identifies their qualification to meet this requirement. Candidates will be determined to be qualified based on the following two factors. These factors are of equal weight. FACTOR 1. Experience - Evaluation of this factor will be based on information submitted by a candidate and feedback from clients which demonstrates applicable, constructive, and affirmative experience in developing and installing at least three instruments, in the field, either: (1) phase measuring interferometers for the measurement of surface figure or transmitted wavefront accuracy of optical components;or, (2) instruments for the measurement of window or wafer thickness variation using non-interferometric methods. Candidates shall either (a) provide a list of at least three clients, the name and telephone number of the client point of contact, the type of instruments which was developed and installed and the date of installation; or (b) where the Key Personnel (see Factor 2 below) in a candidate's organization obtained the necessary experience working for a different organization, the candidate organization shall provide name(s) and telephone number(s) of references which reflect the experience. FACTOR 2 - Qualification of Proposed Key Personnel -Evaluation of this factor will be based on resumes submitted by the candidate which demonstrates the qualifications of the proposed key personnel who will be working on the subsequent contract. The resume must show that the key personnel has knowledge of the optical (for example, design, stray light, speckle, etc.), control (for example phase stepping, data acquisition), and software (for example phase unwrapping, zernike representations, etc) issues involved in the development of the required interferometer for window thickness. Interested candidates shall provide information which demonstrates their qualification and addresses the factors listed above to the National Institute of Standards and Technology, Acquisition and Assistance Division, Building 301, Room B117, Gaithersburg, Maryland 20899 by 3:00 pm local time on September 13, 1996. Submissions will be evaluated. Qualified candidates will be notified and requested to participate in Phase 2 of this acquisition. Phase 2 will be the distribution of a non-disclosure agreement to all qualified candidates. The qualified candidates will be asked to sign a non-disclosure agreement. Candidates who do not sign a non-disclosure agreement will not be considered for contract award. Phase 3 will be the issuance of a Request for Proposal (RFP). The RFP will only be issued to candidates who were determined to be qualified as specified herein and who have signed and returned a non-disclosure agreement within a due date which will be specified when the agreement is distributed. All responsible sources may submit information identifying their qualification which will be considered by the agency. See Numbered Note 26. (0240)
