Spectroradiometer

The Department of Agriculture Agricultural Research Service is soliciting quotations for one spectroradiometer unit via RFQ 1232SA26Q1018, with quotes due August 13, 2026 at 9:00 AM ET. This is a Total Small Business Set-Aside restricted to small business concerns under NAICS 334516 (Analytical Laboratory Instrument Manufacturing), with a 1000-employee size standard.

Place of performance is Geneva, New York. The specification calls for a Spectral Evolution NaturaSpec ULTRA spectroradiometer or equivalent meeting precise technical parameters: spectral range 350–2400 nanometers, spectral resolution less than 2 nanometers at 700 nanometers or below and no larger than 3.8 nanometers above 2000 nanometers, three detector arrays operating across 1000–2500 nanometers (short-wave infrared), at least one detector in the 350–1000 nanometers range, noise equivalence radiance of 0.4 × 10⁹ at 400 nanometers, field-replaceable fiber optic cable, auto-exposure and auto-dark correction, data acquisition software with automatic vegetation indices calculations, live field of view, GPS-linked photo documentation, distance sensor, inclinometer, and hyperspectral satellite/camera calibration capability. The vendor must supply original equipment manufacturer warranty and an OEM-approved calibration kit for end-user annual maintenance.

This is a firm-fixed-price commercial purchase order with delivery required within 50 days of order receipt. Award will be made to the lowest-price technically acceptable quoter with acceptable or neutral past performance, provided price is determined fair and reasonable. Technical acceptability requires submission of a one- to two-sentence Technical Capability Confirmation or a Brand Name or Equal narrative. Quoters must complete the SF 1449 form, submit FAR certifications (52.225-4 and 52.225-18), hold prices firm for 30 days, and may submit questions via email up to 48 hours before closing.
