The spectroradiometer is designed to measure the spectral irradiance, spectral distribution and light intensity of sunlight and solar simulators.

The spectroradiometer, comprised of a CCD-array spectrometer and an integrating sphere, is calibrated by LS-1-CAL-INT, a NIST traceable calibration light source.

The spectrometer must be connected to a PC (or laptop computer) via interface USB 2.0/1.1, and data are obtained by using the furnished software.
