The Exfo NR5000 Radiometer Module is a portable optical power measurement instrument for precise irradiance and power readings across the ultraviolet and visible spectrum. It integrates with EXFO optical test platforms to deliver high-accuracy measurements in laboratory and manufacturing environments. The module employs a proprietary flat-response detector and non-imaging optical interface to minimize measurement variation caused by source radiance and intensity fluctuations, while supporting multiple measurement modes and auto-sensing capabilities.
