SR-4500A Spectroradiometer Offers Range of 350-2500 nm

Press Release Summary:

SR-4500A Spectroradiometer is designed for radiometric calibration transfer and offers a drift stability of 0.1%. The meter is equipped with silicon photodiode array (350-1000nm), 256 elements TE cooled extended In GaAs array (1000-1900nm) and 256 element TE cooled extended In GaAs array (1900-2500nm). The unit uses temperature controller for maintaining the temperature of the housing and features NER of 0.9x10-9 W/cm²/nm/sr at 900 nm and 0.2x10-9 W/cm²/nm/sr at 400 nm and 700 nm.


Original Press Release:

The SR-4500A is Designed for Applications that Require Precise, Stable, Repeatable Performance.

Lawrence, MA – March 27, 2018 – Using all thermoelectrically cooled photodiode arrays, the SR-4500A spectroradiometer is built specifically for the performance demands of radiometric calibration transfer. With the SR-4500A, you can take the calibration process where it’s needed with the following advanced features:

  • Drift stability of 0.1% 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 stabilitzed detector arrays
  • All temperatures are integrated into DARWin software readout for monitoring

The SR-4500A was built to meet the exacting needs of customers for measuring temporal stability. The SR-4500A also features:

  • Spectral range of 350-2500nm
  • 512 element TE cooled silicon photodiode array (350-1000nm)
  • 256 element TE cooled extended In GaAs array (1000-1900nm)
  • 256 element TE cooled extended In GaAs array (1900-2500nm)

In addition to stability, the SR-4500A also provides superior Noise Equivalence Radiance capabilities:

Noise Equivalence Radiance (with 1.2 meter fiber optic)

0.2x10-9 W/cm²/nm/sr @ 400nm

0.2x10-9 W/cm²/nm/sr @ 700nm

0.9x10-9 W/cm²/nm/sr @ 900nm
