The Exfo R5000 is a precision UV/Visible radiometer for measuring light intensity across the 250–600 nm wavelength range. It delivers absolute power, relative, peak hold, and real-time measurement modes with 10 mW resolution across a 10 mW to 15 W dynamic range. The instrument uses a proprietary non-imaging optical interface to eliminate measurement variation from source radiance and intensity fluctuations, paired with a flat response detector that maintains accuracy across the entire specified spectrum.
