SR-4500 Compact Spectroradiometer - New Standard for
Measurement Stability for Radiometric Calibration
The SR-4500 is a portable, compact, UV/VIS/NIR spectroradiometer with three
thermoelectrically cooled photodiode arrays for the ultimate in high performance and
measurement  stability through a wide range of ambient temperatures and
environments.

The SR-4500 is designed to meet the needs of integrating sphere owners doing
radiometric calibration transfer for satellite systems, or for any users who have system
lamps with high operating hours, light sources more than two years old, a mandate for
scheduled calibration, or systems that are just too large to send out for calibration.
With the SR-4500, calibration can be accomplished on-site.
The SR-4500 features:
  • Spectral range of 350-2500nm
  • 512 element TE-cooled silicon photodiode array (350-1000nm)
  • 256 element TE-cooled extended InGaAs photodiode array (1000-1900nm)
  • 256 element TE-cooled extended InGaAs photodiode array (1900-2500nm)
  • Diffraction-based optics for greater reliability (no moving parts)
  • Auto dark current shutter and autoexposure control for one-touch operation
  • NER that is twice as good as a full range spectroradiometer
  • Metal clad fiber optic cable with SMA-905 input - fiber is user-replaceable
    (wrench included)
  • Lightweight and compact with a small benchtop footprint (11 lbs/12 x 4 inches)

DARWin SP Data Acquisition Software

All SPECTRAL EVOLUTION spectroradiometers are equipped with DARWin SP Data
Acquisition software, so that you can take advantage of the following features:
  • Integrated energy measurement tool calculates integrated radiance/irradiance
    for an active spectrum over a user-adjustable wavelength band
  • Upload up-to four user-defined calibration tables for easy transfer
  • Automatically save data as ASCII file to 3rd party software without pre-processing
  • Collect data with a single click
  • Display reflectance/transmittance data (percentage) or absorbance (logarithmic)
    versus wavelength
  • Single and multiple spectral plots available
  • LabVIEW drivers available
  • Built-in solar radiance measurement and spectral match capability
