66 -- INFRARED SPECTROSCOPY AND IMAGING FOURIER TRANSFORM SYSTEM SOL NIH-NIDDK-00-539 DUE 033000 POC Patricia Haun, Purchasing Agent, 301-594-8855 The National Institutes of Health (NIH), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has a requirement to purchase a Time-Resolved Step-Scan Fourier Transform Infrared Spectroscopy system with Integrated Infrared Focal Plane Array Imaging capabilities. The following specifications must be included in the system: 1) A signal-to-noise ratio (SNR) better than 8,000:1 and a standard optical range of 7500-370 cm-1, and have the ability to extend the optical range with the appropriate beamsplitters, sources and detectors; 2) An achievable SNR of 10,000:1 under the following conditions: 5 second background and sample acquisition, 4 cm-1 resolution, peak-to-peak noise from 2200 to 2100 cm-1, Blackman-Harris 3-Term or triangular apodization; 3) Step-scan acquisition capabilities with time resolved capabilities up to 5 microseconds time resolution; 4) The system must be upgradable to achieve 500 picoseconds time resolution; 5) Step-scan capabilities must provide proper input/output support that can be either trigger master or slave. 6) Step-scan capabilities must include both in-step and in-scan co-additions for both point spectroscopy and focal plane array imaging applications; 7) A 4 channel (phase and amplitude modulations) digital-data-processing (DSP) demodulation capabilities suitable for photoacoustic and liquid crystal experiments. The DSP demodulation should be such that no lock-in amplifiers are required; 8) A phase modulation frequency range of 5 to 1,500 Hz and a phase modulation amplitude from 0.1 to 20 lambda (2 lambda up to 800 Hz); 9) The ability to obtain 110 spectra per second at 16 cm-1 spectral resolution in rapid scan mode; 10) Minimum of 2 input emission ports and 3 output port for IR beams; 11) Up to two (2) simultaneously mounted sources and two (2) internal detector positions within the time-resolved spectrometer, selection of specific source and detector must be under computer control; 12) An IR microscope capable of simultaneously housing 2 independent detectors and an integrated, computer controlled XY mapping stage; 13) A standard computer data acquisition and processing station (IBM compatible CPU, monitor, keyboard, mouse, etc.) Computer must include an integrated software packages(s) for data acquisition (standard and time-resolved spectroscopy, as well as, point and focal plan array imaging), 2D and 3D spectral and imaging analysis and mapping stage control; 14) An integrated method and equipment to allow collection of both IR point spectra and IR focal plane array images through an IR microscope; 15) Condensers and Cassegrain objectives for use with the IR microscopes must have variable compensation to allow for thickness differences of sample flats. All data (along with the exact experimental parameters used) demonstrating compliance with performance specifications 1-4, 8 and 9, as listed in the CBD should be submitted with the Request for Quote (RFQ) package. Interested vendors may identify in writing their interest with a capability statement to the Contracting Office prior to the closing date of this notice. This notice is for the purchase of commercial equipment within the Simplified Acquisition Threshold of up to $5 million dollars. It is anticipated that Request for Quotation (RFQ) NIH-NIDDK-00-539 will be available fifteen (15) days after the publication date of this synopsis. Receipt of quotations will be due ten days (10) after the release of the RFQ. The anticipated award date is March 30, 2000. Request for copies of the RFQ must be in writing and may be FAXED to 301-480-4226. Quotations must be submitted in writing to the National Institute of Diabetes and Digestive and Kidney Diseases 6705 Rockledge Drive, Building One, Room 8048, Bethesda, Maryland 20817-7973 Attention: Patricia Haun. FAX quotations must contain offerors names, address, phone number and fax number. FAX quotations will only be accepted if dated and signed by an authorized company representative.
