Spectral Evolution CalibraSpec SR-6500A Spectroradiometer

The Highest Resolution of Any Portable Spectroradiometer Plus Unmatched Drift Stability

The SR-6500A NIR spectroradiometer covers the UV/VIS/NIR range from 350-2500nm. It features ultra high resolution and very stable performance with three high density thermoelectrically cooled photodiode arrays.

The SR-6500A is also calibrated to NIST-traceable radiometric calibration standards.

The SR-6500A offers unmatched drift stability

Using all thermoelectrically cooled photodiode arrays, the SR-6500A spectroradiometer is built specifically for the high performance that demands unsurpassed drift stability. With the SR-6500A, you can take the spectroradiometer where it’s needed and enjoy the following features:

  • Drift stability of ≤0.4% which delivers greater accuracy for long-term stability of integrating spheres
  • Stability is achieved through heating and cooling thermal management features
  • A temperature controller maintains the instrument housing at a stable temperature along with the individually temperature-stabilized detector arrays
  • All temperatures are integrated into DARWin software readout for monitoring
