Presolicitation Notice (FAR 5.101) 1. Point of Contact: Joseph M. Dellinger Contracting Officer Army Contracting Command - APG Adelphi Division 2800 Powder Mill Road Adelphi, MD 20783-1197 joseph.m.dellinger2.civ@army.mil 520-691-4720 2. Set Asides: None 3. PSC Code: 6640 4. NAICS Code: 334516 5. Description: The Detonation Science and Modeling Branch (FCDD-RLA-WA) of the Weapons Sciences Division of the Army Research Directorate (ARD) of the Army Research Laboratory (ARL) requires one (1) high-resolution, high-throughput spectrograph. The spectrograph shall have the following: 1. High-throughput spectrograph shall have intensified camera 2. Shall have a continuous wavelength range from at least 180-1100 nanometer (nm), must be able to see the (carbon) C line at 247 nanometer (nm) and the (oxygen) O line at 777 nanometers (nm) 3. Shall have minimum resolving power (λ/Δλ) of at least 4000 under the specified wavelength range using an intensified charge coupled device (ICCD) detector 4. Shall include a Gen II (or at least comparably efficient) ICCD detector with a S25 18-millimeter (mm) photocathode with quartz window for Ultraviolet, visible, Near-infrared (UV/VIS/NIR) sensitivity 5. Shall have an adjustable gate pulse delay from 0 nanosecond (ns) to at least 500 microseconds (µs) in 5 nanosecond (ns) steps 6. Shall have minimum instrument gate width of 50 nanoseconds (ns) or lower 7. Shall have a modular design that enables exchange of grating cassettes (user interchangeable) and detectors to improve resolving power to at least 50,000. 8. Shall include large f-number (at least f/10) on the input collimator for easy coupling to light collection optics. 9. Shall include small f-number (less than f/3) on the detector focusing optics for high throughput. 10. Shall include large spectrograph demagnification factor (0.2x or greater) to enable large slits at the spectrograph input, but small slit images at the spectrograph focus for high throughput and resolving power. 11. Shall include adjusters for changes in focus for best resolution. 12. Shall have ability to trigger the spectrograph using the q-switch signal from a neodymium: yttrium aluminum garnet laser. 13. Shall have solarization resistant fiber optic cable. 14. Shall have all interface software and hardware required to calibrate and control the instrument. 15. Shall have interface software that produces a linearized wavelength spectrum. 16. Shall weigh less than 40 pounds (lbs) including spectrograph and detector. 17. Shall have dimensions less than 20 inches each in width, length, and height (including spectrograph and detector). 18. Shall include all applicable shipping charges and insurance. 19. Shall have minimum one (1) y…
