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
