The UV-VIS NIR Spectroradiometric Measurement Systems are optimized for the ultraviolet (UV), visible (VIS) and near-infrared (NIR) spectral regions calibrated from 200 nm to 1000 nm (irradiance/radiance) and 300 to 1000 nm (spectral flux). Choose from five (5) options for measuring spectral irradiance (W/cm2-nm) and spectral flux (W/nm). Each Spectroradiometer includes the spectrometer and optical fiber, an optical measurement head for spectral irradiance or spectral flux, a stand, SpectrILight III control software and DLLs, and a carry and storage case. These Spectroradiometer Systems have been fully characterized and are calibrated for their spectroradiometric response following ISO 17025-certified processes, and supported by global recalibration centers in North America, Europe, 
and China.
