About this opportunity
The Department of Agriculture Agricultural Research Service is soliciting procurement of a rugged, field-ready hyperspectral spectrometer system equivalent to the OCTO-FloX produced by JB Hyperspectral Devices GmbH. The system must achieve spectral resolution fine enough to retrieve solar-induced chlorophyll fluorescence (less than 1 nanometer FWHM) across a wavelength range of 500-900 nanometers, enabling simultaneous measurement of multiple vegetation indices including red and far-red solar-induced fluorescence, photochemical reflectance index, and normalized difference vegetation index. The procurement requires the equipment to be rugged and weatherproof (IP67 rated) for outdoor field deployment, capable of rapid sequential measurement across six or more vegetative targets using fixed fiber optics, and equipped with integrated thermal regulation maintaining consistent 20-degree Celsius operation across temperatures ranging from -10 to 50 degrees Celsius. The spectrometer must include automatic optimization of integration time, correction for dark current and detector nonlinearity, wavelength calibration, and radiometric calibration capabilities. The pre-solicitation notice was posted on March 2, 2026, with a deadline of March 16, 2026 for submissions, and only minor follow-on firmware updates are anticipated after the initial delivery.
No set-aside designations have been applied to this procurement opportunity. The notice references JB Hyperspectral Devices GmbH as the manufacturer of the equivalent product specification, suggesting this may represent a competitive requirement or potentially a sole-source justification baseline. The opportunity also includes procurement of a supplementary item (Item 0002), the JB COS Cosine Receptor for solar irradiance measurement, though specifications for this component were truncated in the available documentation. Specific award values, budget ranges, and contract timelines were not disclosed in the pre-solicitation notice. The procurement is classified under NAICS category 334516 (Analytical Laboratory Instrument Manufacturing) and PSC category 6640 (Laboratory Equipment and Supplies), indicating this is a specialized scientific instrumentation acquisition.
Notice text
Requirement for a rugged, field-ready hyperspectral spectrometer capable of sufficiently high spectral resolution to acquire solar-induced chlorophyll fluorescence and sequentially measuring six or more targets. Only minor follow-on work (firmware updates) are expected. Product must be equivalent to the OCTO-FloX produced by JB Hyperspectral Devices GmbH.
Salient characteristics for Item 0001:
The following are minimum specifications and performance criteria for the unit:
• Spectral resolution fine enough to retrieve solar-induced chlorophyll fluorescence (SIF) from telluric and solar absorption features (< 1 nm FWHM).
• Wavelength range wide enough to cover 500 – 900 nm to enable simultaneous acquisition of red SIF at 687 nm; far-red SIF at 760 nm; photochemical reflectance index (PRI) at 530 nm and 570 nm; normalized difference vegetation index (NDVI) and near-infrared reflectance of vegetation (NIRv) at 650 nm and 860 nm.
• Capable of rapid acquisition across multiple (at least 6) vegetative targets in different plots or growth chambers using fixed fiber optics.
• Capable of both hemispherical-conical or bi-hemispherical configurations, adjustable by user through removable cosine correctors designed for outdoor use.
• Weatherproof (IP67 rated) to allow deployment of unit in variable outdoor environments.
• Integrated thermal regulation to maintain spectrometer temperature consistently at 20 degrees Celsius. Intelligent temperature management modes for power saving. Heatingo for cold conditions.
• System operational temperature range from -10 to 50 degrees Celsius.• Automatic optimization of integration time to maximize spectrometer dynamic range across 0-2000 PPFD.
• Correction for dark current and detector nonlinearity.
• Wavelength calibration and optimization of spectral shift.
• Radiometric calibration for both bare fiber and cosine corrected fiber configurations.
Salient characteristics for Item 0002 –
JB COS Cosine Receptor for the measurement of solar irradiance. Must be equivalent to the JB COS produced by JB Hyperspectral.
Salient Characteristics for Item 0002:
• Must be 100 percent compatible with the other item(s) described in this notice (see Item 0001).
• Cosine error of < 10% at 80 degrees
• Spectral range of 400 nm - 1000 nm
