66 -- AUTOMATED SPECTRORADIOMETRIC MEASUREMENT SYSTEMS POC Sandra Wheeler, EG&G Florida, Inc., BOC-110, Kennedy Space Center, FL 32899 (407)867-7869. EG&G Florida, Inc., in support of NASA at the Kennedy Space Center, intends to award on a sole source basis a contract for an Automated Spectroradiometric Measurement System to Optronic Laboratories, Inc. of Orlando, FL. The system must be configured for measuring spectral response of photodetectors (250 to 2400 nm), spectral radiance of light sources (250 to 2400 nm), spectral irradiance of light sources (250 to 2400 nm), spectral specular reflectance as a function of angle of incidence (250 to 2400 nm), and spectral transmittance as a function of angle of incidence (250 to 2400 nm) with wavelength selection accuracy +or-0.05%, wavelength precision (repeatability) of +or-0.01% and the calibration transfer capability of +or-0.5% from standard to test device. The system will include: 1) A true double grating (Czerny-Turner design) monochromator mounted on a single base plate with two automated tri-grating turrets capable of holding three gratings along with a minimum 11 - position, automated second order blocking filter wheel and a variable speed optical chopper built into the monochromator, 2) A signal detection system consisting of a high sensitivity TE cooled PbS detector calibrated (NIST traceable) for spectral response over the wavelength range of 1000 to 3000 nm, 3) An S-20 response photomultiplier, with a programmable, high voltage power supply for operation of the photomultiplier, and 4) An AC synchronous lock-in amplification system using DSP technology with the capability of DC amplification and upgrading for photon counting. The general operating software will include routines for automatic wavelength calibration of the gratings and automatic switching of signal detection systems, automatically positioning the optical chopper in the open position when the chopper is turned off, varying the frequency of the optical chopper, and giving the user complete control to operate the spectroradiometer manually. The system must be compatible with Optronic OL 740A-D accessories currently in use including input & exit optics modules and OL 7305C detectors. The intent of this synopsis is to determine if any other source(s) exist, therefore no RFP/RFQ is available. Interested firms are invited to submit a response within fifteen (15) calendars days after publication of this notice which must include price and technical data sufficient to determine capability to meet the requirement. Data packages may be sent to: Sandra Wheeler, BOC-110, EG&G Florida, Inc., Kennedy Space Center, FL 32899. (0157)
