The SR-4500 and SR-4500A are portable, compact, UV/VIS/NIR spectroradiometers 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 and SR-4500A are designed to meet the needs of integrating sphere owners doing radiometric calibration transfer for integrating spheres used 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 and SR-4500A, calibration can be accomplished on-site.
