About this file
This is a Statement of Work for the Library of Congress to procure a research-grade Fiber Optic Reflectance Spectrophotometer (FORS) system. The Library's Preservation Research and Testing Division requires this equipment to replace an existing unit reaching end-of-life and to expand capability for non-destructive analytical research of collection materials, materials characterization, and environmental degradation assessment across ultraviolet, visible, and near-infrared spectra.
The spectrophotometer system must include a portable, field-ready unit with a spectral range of 350-2500 nm or better and spectral resolution better than 5 nm at ~700 nm and 10 nm at longer wavelengths (~1400-2100 nm). The system shall support different optical fiber-based probes for reflectance measurements with future transmission capability and connectivity to customer-provided computers with integrated software for data collection, interpretation, and export to standard file formats. Required components include a contact probe with integrated halogen light source (10 mm spot size or better), a 1.5-meter fiber optic jumper cable composed of low-OH fibers, two bifurcated reflectance probes (2000-micron and 600-micron diameters), and a fiber optic illumination source with standard interfaces. Additional deliverables include necessary accessories such as spacers, optical attenuators, Spectralon calibration reference, carrying case, and power supply.
The contractor must deliver the complete system to the Library of Congress, Madison Building, within 90 days after contract start, with payment upon delivery and acceptance. Freight shipping is the contractor's responsibility, with additional loading dock instructions to be provided post-award. The contractor shall provide one-year manufacturer warranty on all supplied items, including covered remote support via phone and email, commencing upon Library acceptance. The shipping address is Library of Congress, Attention: Eric Monroe, Preservation Research and Testing Division LM G-52, 101 Independence Ave SE, LA224, Washington, DC 20540-4560.

Statement of Work – Fiber Optic Reflectance Spectrophotometer (FORS)
1. OVERVIEW / BACKGROUND. The Library of Congress (Library) requires contract support to acquire a research-grade fiber optic reflectance spectrophotometer (FORS) for use in ongoing long term scientific studies as well as application to studies of the Library of Congress’ collections. This purchase will replace an existing unit that is reaching the end of its support lifecycle and expand the utility of the technique for non-destructive analytical research with collection objects and research programs, materials characterization, and the assessment of environmental degradation parameters of a broad range of Library collection materials by tracking change over time and the impact of environment. This acquisition shall include a wide range spectrophotometer, light source(s), fiber optics, and probes as needed to allow for the non-destructive spectral analysis of materials across the ultraviolet, visible, and near infrared spectrum.
2. SCOPE. The Preservation Research and Testing Division (PRTD) requires a research-grade fiber optic reflectance spectrophotometer (FORS) for use in ongoing long term scientific studies as well as application to studies of the Library of Congress’ collections. This purchase will be utilized for non-destructive analytical research with collection objects and research programs, materials characterization, and the assessment of environmental degradation parameters of a broad range of Library collection materials by tracking change over time and the impact of environment. This acquisition shall include a wide range spectrophotometer, light source(s), fiber optics, and probes as needed to allow for the non-destructive spectral analysis of materials across the ultraviolet, visible, and near infrared spectrum.
3. REQUIREMENTS
3.1. The Fiber Optic Spectrophotometer shall contain the following specifications/characteristics:
3.1.1 Portable, field ready form factor.
3.1.2 Ability to utilize different optical fiber-based probes for reflectance measurements.
3.1.3 Availability of additional accessories to perform transmission measurements (for future experimental capability expansion.)
3.1.4 A spectral range of 350-2500 nm or better.
3.1.5 Spectral resolution of better than 5 nm at short wavelengths (~700 nm) and 10 nm at longer wavelengths (~1400-2100 nm).
3.1.6 Connectivity to customer provided laptop or computer with integrated software control of data collection, interpretation, and export to standard file types.
3.2. The light source(s) and probes shall contain the following specifications and/or characteristics:
3.2.1 Contact probe with integrated halogen light source for non-destructive analyses with a spot size of 10 mm or better.
3.2.2 Fiber optic jumper cable with a length of 1.5 m composed of low OH fibers.
3.2.3 Two reflectance probes consisting of bifurcated optical fibers. One probe shall be of a larger diameter (2000 micron diameter) with the other, smaller diameter probe having a diameter of 600 micron.)
3.3.3 Fiber optic illumination source with standard fiber optic interfaces and broad wavelength output consistent with the spectral range of the spectrometer in 3.1.
3.3. The contractor shall provide any additional accessories needed for the characterization and use of the above items including any spacers, optical attenuator, Spectralon (for white reflectance calibration), carrying case, power supply, etc.
3.4 The contractor shall provide freight shipping to the Library of Congress, Madison Building, to be coordinated with the COR. Note that additional shipping instructions required for gaining access to the loading dock will be supplied following contract award.
3.5 The contractor shall provide one-year manufacturer warranty on all supplied items along with covered remote support (phone, email, etc.)
