Description

NASA/LaRC is hereby soliciting information for potential sources for piezo-electric tuned (PZT) etalon spectral filters with the following specifications: (1) Center Wavelength: (532 nm +/- TBD) (1064 nm +/- TBD); (2) Free Spectral Range (FSR): (0.75 nm) (1.5 nm); (3) Nominal Bandpass (FWHM): (35 pm +/- TBD) (70 pm +/- TBD); (4) Clear Aperture: (min. 29 mm) (min. 29 mm); (5) Peak Transmission: (>= 75%) (>= 75%); (6) Out-of-Band Blocking (avg): (1E-4) (1E-6); (7) On-Orbit Tuning Range: (0.75 nm) (1.5 nm); and (8)Environmental: Acoustic Vibration -- 15.3 Grms, three axes, Survival temperature(-20 to + 50C) The Contractor shall supply two piezo-electric tuned capacity stabilized Fabry-Perot etalon spectral filters and their accompanying electronic control units satisfying the performance specifications listed above. The etalons shall be equivalent to space flight-like assemblies and shall be treated and handled according to conditions commensurate with cleanliness standards established for spaceflight hardware. Documentation reflecting the quality assurance aspects of the etalon optical assemblies shall be forwarded with the units verifying their pedigree and traceability to approved materials, parts, and quality assurance standards. The optical assemblies shall be mounted in a cage assembly used on previous units (e.g., Geoscience Laser Altimeter System) and in its own thermally controlled oven. The oven shall allow temperature control of the etalon over the range, +30 degrees C to +40 degrees C. The etalon mount design shall be such that the etalon can be removed from the oven as a unit without impacting etalon alignment. The electronics accompanying each etalon optical assembly shall be assembled using laboratory grade parts and shall have a PC-104 configuration. The electronic assemblies shall have the capability of at least a 12 bit control system and be designed such that a one-to-one part replacement shall allow for the use of high reliability, space radiation hardened components to permit qualification of the units for spaceflight. Control algorithms for maintaining accurate etalon plate separation using built-in capacitance feedback system shall be programmed into the electronic hardware. Documentation shall include: parts list; electrical schematics; signal timing plots; control algorithm description; etc. Test documentation and procedures shall be a deliverable. A final report on each unit shall include a narrative description of the performance of each unit. In addition, sections of the final report shall include plots of: spectral bandpass; input command setting vs. center wavelength; interface power supply requirements. No solicitation exists; therefore, do not request a copy of the solicitation. If a solicitation is released it will be synopsized in the CBD and on the NASA Acquisition Internet Service. It is the potential offerors responsibility to monitor these cites for the release of any solicitation or synopsis. Vendors having the capabilities necessary to meet or exceed the stated requirements are invited to submit appropriate documentation, literature, brochures, and references. Responses must include the name and address of firm and the size of business (i.e. large, small, small disadvantaged, 8(a), HUBZone, and/or woman-owned). Technical questions should be directed to l.p.kopia@larc.nasa.gov. Procurement related questions should be directed to r.i.hollifield@larc.nasa.gov. Please advise if the requirement is considered to be a commercial or commercial-type product. A commercial item is defined in Internet "Note A". This synopsis is for information and planning purposes and is not to be construed as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resultant solicitation for the requirement. The Government reserves the right to consider a small business or 8(a) set-aside based on responses hereto. All responses shall be submitted to Roberta Hollifield no later than January 19, 2001. In responding reference 1-025-PZT. Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nasanote.html
