OCTO - FloX System

2026-11-03

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
