Setting New Standards In Electro-Optical Testing

SR-5000N Spectroradiometer


The SR-5000N IR spectroradiometer is the result of the latest new redesign of the SR 5000, the CI Systems’ flagship product for the last 35 years. The SR 5000N spectroradiometer measures the spectral signatures of objects from a distance which can vary from a few meters to many kilometers. The measurements can be done either spectrally, yielding radiance as function of wavelength or radiometrically to obtain radiance as function of time. The SR5000N is the ideal spectroradiometer for research applications of Remote Sensing, due to the wide spectral range covered (from UV to LWIR), the high sensitivity of the cooled detectors used in the system, and the accuracy of the radiometric calibration based on our state-of-the-art blackbodies. Some instrument parameters (such as field of view, focusing distance, measurement time and others) can be controlled by the user so that, together with the user friendly interface, the work becomes efficient and easy.
