Spectral Evolution’s SR-6500A has the highest resolution of any portable spectroradiometer plus unmatched drift stability

• Rating12345

Haverhill, MA  – Using all thermoelectrically cooled photodiode arrays and custom heating and cooling management features, the SR-6500A spectroradiometer is built specifically for high performance that demands unsurpassed drift stability. The SR-6500A features:

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

The SR-6500A delivers the highest resolution available in a portable spectroradiometer:

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

The SR-6500A also delivers high sensitivity with Noise Equivalence Radiance (NER) performance with a 1.5 meter fiber optic at:

• 0.8 x 10^-9 W/cm²/nm/sr @ 400nm
• 0.3 x 10^-9 W/cm²/nm/sr @ 1500nm
• 5.8 x 10^-9 W/cm²/nm/sr @ 2100nm
