The LS-100 grating spectroradiometer is specially designed for use in measuring the spectral irradiance of solar simulators that are used for the measurement of photovoltaic cells. The LS-100 is calibrated against a NIST-traceable standard lamp. Its size is compact and it is very easy to operate. The LS-100 must be connected to a PC (or laptop computer) via a RS232C cable, and data are obtained using the furnished (included) software. The measurement/analysis software is used to process the obtained data as follows;
