Original Press Release:

Take the Ultra-High Resolution SR-6500 Spectroradiometer to the Field

The SR-6500 is designed for applications that require ultra-high spectral resolution.

The SPECTRAL EVOLUTION SR-6500 NIR spectroradiometer covers the UV/VIS/NIR range from 350-2500 nm. It features ultra-high resolution and very stable performance with three high sensitivity thermoelectrically cooled photodiode arrays. The SR-6500 is also calibrated to NIST-traceable radiometric calibration standards. Now with two rechargeable lithium-ion batteries, you can take this ultra-high resolution spectroradiometer to the field for in situ measurements.

Resolution at FWHM for the SR6500 is:

  • 1.5nm @ 700nm
  • 3.0nm @ 1500nm
  • 3.8nm @ 2100nm

Resolution is achieved using three high density solid state thermoelectrically cooled photodiode arrays:

  • 1024 element TE-cooled silicon photodiode 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) performance 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

NER is a measure of instrument sensitivity. Other features of the SR-6500 include:

  • All fixed optics – no moving parts for rugged reliability
  • Auto-exposure, auto dark current shutter
  • DARWin SP Data Acquisition software saves all scans as ASCII files for use with other software programs

The SR-6500 includes wireless Bluetooth and USB communications and has an operating range from 0-40°C. Physical parameters include:

  • Dimensions: 12.4 x 8.7 x 4.4 inches (31.5 x 22.9 x 38.7 cm)
  • Weight: 11 pounds (4.99 kg)

For field work, the SR-6500 can be placed in a backpack. It runs off one lithium-ion battery. Two are provided for up to 6 hours of in-field scanning.

Equipped with our Miniprobe (3mm spot size), the SR-6500 brings high resolution to a range of applications, including:

  • Mineral identification and analysis where resolution can help to distinguish between minerals with very similar spectra or to unmix and identify minerals in trace amounts.
  • Soil studies for the identification of different soil characteristics, clay types, presence or absence of nutrients and moisture.
  • Vegetation studies for plant stress/health, over-fertilization, species identification and more.
  • Lab applications such as materials identification, etc.
  • Solar radiance and irradiance research.
  • Microbial diversity research
