Press Release:
Field Portable Spectroradiometer for Validating AVIRIS-NG. The SR-6500 is designed for applications that require superior spectral resolution.
Lawrence, MA – June 12, 2018 –AVIRIS-NG is a unique optical sensor that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral channels (bands) with wavelengths from 400 to 2500 nanometers with a 5nm sampling. The main objective of the AVIRIS-NG project is to identify, measure, and monitor constituents of the Earth’s surface and atmosphere based on molecular absorption and particle scattering
signatures. Research with AVIRIS-NG data is predominantly focused on understandingprocesses related to the global environment and climate change. Most recently, AVIRIS-NG has been used for measurements spanning coastal zone, mangrove forest, soils, hydrocarbon alteration, mineralogy and other application areas.
The SR-6500 is a full range system that meets this high spectral resolution requirement. The SR-6500 is calculated for radiance with NIST-traceable standards.
It features superior resolution at FWHM:
1.5nm @ 700nm
3.0nm @ 1500nm
3.8nm @ 2100nm
Ultra-high resolution is achieved using three high density solid state thermoelectrically
cooled photodiode arrays:
1024 element TE-cooled silicon phtotodiode array detector (VIS-NIR)
512 element TE-cooled InGaAs photodiode array detector (SWIR 1)
512 element TE-cooled extended InGaAs photodiode array detector (SWIR 2)
The SR-6500 features the following Noise Equivalence Radiance (NER) sensitivity with
a 1.5 meter fiber optic:
1.0 x 10-9 W/cm2/nm/sr @ 400nm
2.8 x 10-9 W/cm2/nm/sr @ 1500nm
6.8 x 10-9 W/cm2/nm/sr @ 2100nm
The SR-6500 is available with optional EZ-ID sample identification software with three mineral spectral libraries for soil analysis and mineral identification. A Custom Library Builder module allows you to build your own library by scanning known samples and saving these high resolution scans to match against.
