STATEMENT OF WORK

Princeton Instruments Isoplane 320 Aberration-Free Imaging Spectrograph with Pixis 400BRX High-Resolution With Charge Coupled Device (CCD) Detector and LightField Software

(BRAND NAME OR EQUAL)

I. BACKGROUND INFORMATION

NIST has an immediate need to procure a high-resolution, aberration free, imaging spectrograph and charge-coupled device (CCD)-detector to be utilized for Raman spectroscopy and imaging applications in the visible and near-infrared spectral range from 400 nm - 1100 nm. The spectrograph must be free from coma and astigmatism across the entire image plane of the CCD and is to be used for high wavelength and photometric accuracy Raman measurements utilizing excitation wavelengths that include, but are not limited to, 488 nm, 532 nm, 633 nm, 647 nm, 785 nm and 830 nm. Existing lasers and optical components will be utilized with the spectrograph and are not part of the present requirement. The spectrograph will be used to support the Raman standard reference materials program at NIST. In addition, it will be utilized for Raman measurements of chemical and biological sample analysis with high sensitivity and throughput. The specifications below are motivated by the need to achieve high wavelength accuracy and photometric performance across a broad spectral range for single and multi-track Raman spectroscopic applications.
