Applications
Mining
SPECTRAL EVOLUTION NIR field spectrometers and spectroradiometers are used worldwide in mining exploration, mineral identification, mining production, geological remote sensing, and ground truthing of multi-spectral and hyperspectral imagery. Our EZ-ID™ software provides real-time mineral identification using the USGS, SpecMIN™ and GeoSPEC mineral spectral libraries. All data is saved in ASCII files for use with 3rd party application software without pre-processing. Our oreXpress™, oreXplorer and oreXpert instruments save geologists time and money in exploring for gold, copper, nickel, uranium, rare earths and more. These instruments are used in field exploration, mineral mapping, alteration mapping, and core logging.
Remote Sensing
SPECTRAL EVOLUTION is a leading manufacturer of NIR field portable and laboratory spectroradiometers and spectrometers for remote sensing applications including geological remote sensing, ground truthing, spectral remote sensing, environmental and climate research, crop and soil research, vegetative studies, forestry and canopy studies, radiometric calibration transfer, upwelling and downwelling measurement, radiance and irradiance measurements and more. Instruments including the SR-6500, the PSR+, the RS-8800, the NaturaSpec and the RS-3500 are designed for researchers in the field – lightweight, rugged construction, and reliable operation while providing high resolution/high sensitivity measurements.
Solar
Solar manufacturers are concerned with manufacturing efficiencies and auditable and reliable QA/QC to accurately measure the performance of cells and modules and meet customer guarantees. Solar simulators are used in quality monitoring to provide the necessary data. To ensure consistent and accurate measurement and data, the solar simulator requires testing to be certain it meets its classification. Classification is based on both IEC 60904-9 and ASTM E927-10 standards and can be Class A, Class B, or Class C depending on the acceptable tolerances they meet for spectral match to sunlight, uniformity of light source, and stability of light source over time. SPECTRAL EVOLUTION’S SR-3501, SR-1901 and SR-1901PT can characterize continuous and pulsed solar simulators to ensure that they meet the appropriate standards.
Radiometric Calibration
SPECTRAL EVOLUTION SR-4500 and SR-4500A NIR spectroradiometers deliver stable temperature control across a range of ambient temperatures and environments. Using all thermoelectrically cooled photodiode arrays, the SR-4500 and SR-4500A are built specifically for the performance demands of radiometric calibration transfer. With the SR-4500 and SR-4500A, you can take the calibration process where it’s needed.
