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
