LS-100 Spectroradiometer

  • Measures spectral irradiance 350 to 1100nm
  • Calculates the integrated irradiance in the specified spectral range
  • Calculates the spectral coincidence (JIS C 8912)
  • Calculates the difference and ratio compared to the standard data

The LS-100 grating spectroradiometer is specifically designed for measuring the spectral irradiance of solar simulators which are used in solar cell research. The LS-100 is calibrated against a NIST-traceable standard lamp. It is compact and very easy to operate. The LS-100 is controlled by a PC via an RS232C cable, so that data can be automatically obtained using the operating software. The measurement/analysis software offers advanced functionalities in order to process the obtained data.
