About this file
This document is a combined synopsis/solicitation for a federal contract opportunity to purchase a Raman imaging spectrograph and a highly sensitive camera. The ARS Environmental Microbial and Food Safety Laboratory (EMFSL) in Beltsville, Maryland requires these components to develop a new compact macro-scale line-scan Raman chemical imaging system for food safety research. The spectrograph and camera must work at 808 nm excitation to ensure high-quality Raman scattering signals.
The solicitation number is 12305B24Q0071, and it is a full and open acquisition with no set-aside. Offers must demonstrate technical capability to meet the detailed performance and technical specifications provided in Attachment 1. Award will be made on a best value basis considering price, technical capability, and delivery within 60 days. Offerors must submit a firm fixed price quotation, Unique Entity ID, and supporting documentation by the April 26, 2024 due date. The contracting officer may conduct discussions if deemed in the government's best interest.

RAMAN IMAGING SPECTROGRAPH AND CAMERA SPECIFICATIONS
I. BACKGROUND
The ARS Environmental Microbial and Food Safety Laboratory (EMFSL) in Beltsville, Maryland plans to purchase a Raman imaging spectrograph and a highly sensitive camera to develop a new compact macro-scale line-scan Raman chemical imaging system for food safety research. Since the spectrograph and the camera will need to work with a recently purchased 808 nm high-power diode line laser to form the whole measurement system, these two hardware components must work and optimize at 808 nm excitation to ensure high-quality Raman scattering signals to inspect food and agricultural products.
II. REQUIREMENTS
The Raman imaging spectrograph and camera must be capable of the following:
• Spectrograph laser excitation wavelength: 808 nm
• Spectrograph wavenumber range: 200 to 2800 cm-1
• Spectrograph spatial channels: >= 1024
• Spectrograph spectral resolution: <= 16 cm-1 (using a 35 μm slit)
• Spectrograph field of view: >= 250 mm at 400 mm working distance
• Spectrograph size: <= 75×150×150 mm3
• Spectrograph weight: <= 4 kg
• Spectrograph type: line-scan push-broom
• Spectrograph configuration: non-contact macro-scale imaging (no fiber optics)
• Camera quantum efficiency: >= 75% at 900 nm and >=30% at 1000 nm
• Camera active pixels: >= 1024×1024
• Camera frame rate: >= 4 fps at full frame
• Camera digitization: >= 16-bit
• Camera linearity: >= 99%
• Camera air cooled temperature: <= -80 ºC for the CCD detector
• Camera lens mount: C-mount
• Camera interface: USB
• Camera software development kit (SDK) support: LabVIEW
III. Delivery
• 60 Days After Award
• Bldg. 303, BARC-East, 303 Powder Mill Rd., Beltsville, MD 20705
