MS-700N Spectroradiometer

MS-700N Spectroradiometer

Features

  • New reference for spectral UV - VIS - NIR
  • High optical resolution <10nm
  • Extended operating temperature range -10 to 50ºC
  • Made for outdoor solar research
  • Robust design no moving parts
The new generation grating spectroradiometer MS-700N is designed to provide the most accurate solar spectral data outdoors. The MS-700N is a unique all weather sensor, without any moving parts. The detector core is temperature controlled to provide accurate irradiance measurement data within the spectral range from 350nm to 1050nm (UV / Visible / NIR). 
MS-700N is accurately calibrated with traceability to the International Standards and issued with a calibration uncertainty budget. The rugged optical design of the diffusor and input optics make the MS concept superior to any fiber optic spectroradiometer which will be susceptible to mechnical vibration and handling. The MS spectroradiometers are designed for permanent installation, but are are perfectly suited as a traveling reference. 
MS-700N has a separate power supply unit and can be controlled through RS232 / 422 by a PC or data logger. The PC software provides different functions for operating, data management and visualisation. Through the open command protocol of the defined system control functions, software can be developed by the individal user. Measuring spectral irradiance is a must to understand the effect of the non-uniform energy distribution of the sun. Since the solar spectrum varies as a function of air-mass and composition of the atmosphere, the MS-700N reveals those details. While thermopile pyrheliometers and pyranometers are most suitable to quantify the total DNI or global radiation (W/m2), spectroradiometers give detail about the energy distribution (W/m2/nm), which is most important for PV or CPV cell research and performance analysis.
