Spectroradiometric Systems, or Spectroradiometers, measure spectral irradiance as a function of wavelength. They are typically used to measure the spectral output of an unknown or to calibrate measurement systems. In photovoltaics testing, spectral irradiance is needed in order to calculate the spectral mismatch between the test light source (typically a xenon lamp), and a reference spectrum (typically AM1.5G). The set-up shown on the left is used in Newport’s Technology and Applications Center Photovoltaics Lab to calibrate Silicon Reference Cells and calculate their spectral mismatch. Most spectroscopic systems include Monochromators with single point detectors, others, spectrographs with array detectors. The modular design of the Oriel product line allows the Researcher to custom design and build his system to meet his need; for example, the Oriel line offers various gratings, order sorting filters and detectors for scanning in UV-VIS and/or in the IR.
