The SR-6500 portable spectroradiometer provides the ultimate in high resolution measurement for
applications where the ability to see and save additional information about absorbance and reflectance features is critical. The SR-6500 is a full range UV/VIS/NIR specrtroradiometer covering the
350-2500nm spectral range. It is designed with three thermoelectrically cooled photodiode arrays for the ultimate in stable performance. The photodiode arrays are:
   -1024 element TE-cooled silicon detector array covering wavelengths from 350 to 1000nm
   -512 element TE-cooled InGaAs detector array covering wavelengths from 1000 to 1630nm
   -512 element TE-cooled extended InGaAs detector array covering wavelengths from
1630 to 2500nm
The SR-6500 delivers very high resolution for accurate and precise spectra. Resolution is:
   -1.5nm @ 700nm
   -3.0nm @ 1500nm
   -3.8nm @ 2100nm
The spectroradiometer can be used with bare fiber or FOV (field-of-view) fiber-attached lenses and a high-power light source, or with our convenient handheld Miniprobe, a sample contact probe with a built-in light source and 3mm spot size.
With the Miniprobe, the SR-6500 is well-suited for capturing high resolution scans of minerals in samples from mining exploration. These scans will show additional features not seen with standard field spectrometers or spectroradiometers allowing for better identifications and analysis of the
minerals in the sample and affording a geologist an impressive tool for unmixing minerals in samples.
When used with Spectral Evolution’s EZ-ID mineral identification software and two spectral libraries of more than 600 minerals, the SR-6500
offers new insight into mineral alteration and vectors to ore bodies.
The SR-6500 includes our DARWin SP
Data Acquisition software for instrument control and data acquisition and saves all files as ASCII for easy use with other analysis software.
