66 -- LIQUID NITROGEN COOLED LOW LIGHT LEVEL CCD IMAGING SPECTROSCOPY SYSTEM SOL 52SBNB5C8797 DUE 080195 POC Stacy Bostjanick (301) 974-6339; Contracting Officer: Phyllis A. Bower The National Institute of Standards and Technology (NIST) intends to negotiate on a sole source basis under the authority of 41 USC 253(C)(1). The supplies and services required by the Agency are available from only one responsible source and no other supplier will satisfy the needs of the Agency. It is anticipated to negotiate with the sole manufacturer, Inovision Corporation, 2810 Meridian Parkway, Suite 148, Durham, NC 27713, for a Liquid Nitrogen cooled low light level CCD imaging spectroscopy system. This will consist of control through the VME interface to Hewlett- Packard 9000 series 700 workstations, Unix-based camera control and image processing software with X11/Motif graphical user interface including: basic camera control (define region of interest, exposure time, focus mode, independent parallel and serial binning on chip or in software, background subtraction, flat field correction, temperature control), image processing (line profiles, derivatives, standard filters, smoothing and baseline fitting functions, contrast enhancements, rotations, color tables), scripting language, 16-bit data handling; CCD array back-thinned and antireflection (visible-near infrared) coated to achieve room temperature quantum efficiency (QE) exceeding: ) 60% at 400 nm, )70% at 500-750nm, )40% at 900 nm; 1024 X1024 pixels on 25 X 25 mm `imaging area; grade 1 or equivalent specification on CCD; dark charge( electron/pixel-hr at -120C; read our noise 10 electrons maximum; 50 kpixels/sec data rate; 16 bit dynamic range; nonlinearity ( 1%; Gain: at least two user selectable gain settings allowing optimization of system noise or of dynamic range. Approximate gain settings to be 1 el/ADC unit and 4-7 el/ADC unit.; light tight shutter with ( 10 msec open and close times, )2.5Hz rep rate; liquid nitrogen colled dewar housing with minimum hold time of 10 hrs with 0.5 liter; dewar and array mounted for spectrometer in normal horizontal position (vertical slits); liquid nitrogen (LN) cooled and thermostatted CCD stage with +0.1 deg temperature regulation from -80 to -120C; CCD camera to be integrated with 0.155m f/4 Czerney-Turner type imaging spectrometer which shall have the following specifications: corrected optics to provide spectral imaging over 25X12 mm flat field, computer controlled interchangeable dual grating, resolution with a 1200 gr/mm grating and 10 micrometer slits shall be 0.4 nm or better, scanning range 0-1400 nm with a 1200gr/mm gratting, micrometer adjustable slits from 10mu m to 3 mm, direct digital scanning via RS-232, interchangeable dual grating turret capability and permit three turrets to be used with the same spectrometer, two dual grating turrets (aligned for the spectrometer) will be supplied with the following gratings: 1200 gr/mm blazed at 750 nm, 600 gr/mm blazed at 650 nm, 300 gr/mm blazed at 640 nm, 300 gr/mm blazed at 760 nm; install system at NIST and integrate with NIST HP 700 computers. Demonstrate that the system meets above specifications. Vendor shall provide documentation for the software and shall provide correction of all software errors. FOB Destination, Gaithersburg, MD -- Required Delivery Time is 90 days after award -- Interested offerors may identify their interest and capability to respond to the requirements by submitting a capability statement. The capability statement must provide adequate information to allow evaluation of the System. All of the above must be provided for the Government to consider whether to open this requirement for competition. This notice of intent is not a request for competitive proposals. However, all ''ccapability statements'' received within 45 days after the date of this publication in the Commerce Business Daily will be considered by the Government. A solicitation is not available. See Numbered Note 22. (0174)
