- Description
- The Optical Technology Division of the National Institute of Standards and Technology (NIST) has a requirement for Infrared Bandpass filters per the following Statement of Work and specifications: It is the goal of the LBIR Facility to procure IR filters with the following properties: 1)Filters need to function at 10 K. Filter band passes usually just scale with thermal contraction of the film thickness. This shift is usually small and not an issue. Substrate transmission can change very significantly. We (NIST) have cryogenic transmission measurement capability to assist in this portion of the project for proposed substrates; 2) All filters to be approximately 1 micron band pass (not a strict requirement); 3)The filter band edges should transition within 250 nm from 5 % transmission to 5 % less than average transmission along the central portion of the pass band; 4) Less than 0.1% out of band leakage for all other wavelengths, 2 - 30 microns. Would prefer 2 - 70 microns as could be achieved when substrate is 2 mm thick ZnSe. ZnSe blocks very well from 24 - 70 microns at 10 K. We have cryogenic transmission curves out to 100 microns for CaF2, KRS-5, MgF, ZnSe and ZnS that will be provided to bidders for filter development; 5) Transmission peak need not be flat. Variations in band pass of less that 10% are preferred, greater variations may be considered. Central transmission average may be as low as 60% if necessary; 6) Size: Total filter thickness must be 3 mm or thinner, and filter diameter must be approximately 1" in diameter but not greater; 7) Beam redirection by filter must be less than 1 microradian, therefore filter surfaces must be parallel to better than 1 arcmin; and 8) Filters should cover the spectral range of 5 to 15 microns in approximately 1 micron increments. (For example: a.6 - 7 microns; b. 7 - 8 microns; c. 8 - 9 microns; d. etc.). This would result in filters approximately centered on 5.5 microns, 6.5 microns, 7.5 microns, ?13.5 microns, and 15.5 microns. We will possibly order 10 of each filter, or some other quantity depending on how many filters the offeror can make in a single batch production. Filter similarity is of high importance to the program. Though no stringent specification is available at this time, effort should be made such that filters within a given wavelength batch are as similar as can be reasonably made within a given fabrication deposition run. In an effort to reduce this large risk, filters at one or two wavelengths will be purchased from vendors that submit a satisfactory proposal for a filter at a satisfactory price. Vendors should submit proposals at filter wavelengths that represent medium to high risk in development. Once proof of capability has been established with the more difficult filters, the remaining filters will be purchased through a second procurement solicitation. The proposals for this initial solicitation are required to contain at a minimum the theoretically modeled spectra submitted in tab-delimited text format, the proposed substrate material and its thickness, the cost, and the delivery time. Proposals will be evaluated based on the following criterion: 1) The ability to meet the above properties (this will be judged based on the modeled spectra that is to be submitted in tab-delimited text format and the proposed substrate material and thickness); 2) Cost; and 3) Delivery time. Multiple vendors may be chosen for the initial risk reduction phase of the procurement. However, being chosen for this initial phase of the total procurement is not an indication of selection for the final phase of the procurement where the remaining filters will be purchased. Selection of the vendor for the final phase of the procurement effort will be based on the performance of the delivered filters, the cost of the remaining filters, and the predicted delivery time. The final phase of the procurement will be initiated at a later date, therefore proposals for the complete set of filters will not be considered at this time. Please mail proposals to: Sherri Miller, Purchasing Agent, NIST, 100 Bureau Drive, M/S 3571, Gaithersburg, MD 20899-3571 by the closing date of this notice. Proposals may also be submitted by facsimile to (301) 975-2541. Questions should be submitted to sherri.miller@nist.gov.
