제품특징

The MS-713 can be used stand alone, but is commonly used in combination with the MS-711. It covers the spectral range from 300nm to 2550nm. Made for Solar research activities which require spectral information measured in a very broad spectral range. Such as ground validation of satellite spectral data or future Solar energy research and resource assessment. The MS-713 all weather spectroradiometer in combination with MS-711 extend the range to 2550nm and measure >98% of the integrated solar terrestrial spectrum.

The MS-711 and MS-713 spectroradiometer are unique all weather concept spectroradiometers with no moving parts and temperature controlled spectrometers. The MS-713 can be used stand alone, but in combination with the MS-711 it covers the spectral range from 300nm to 2550nm. MS-711 measures in the range from 300nm and 1100nm, and MS-713 covers the near-infrared (NIR) range between 900nm and 2550nm. Both spectroradiometers are accurately calibrated with traceability to the International Standards and issued with a calibration uncertainty budget.

Temperature changes of the detector inside the spectrometer have a strong effect on the measurement uncertainity. Therefore the sensor unit inside the MS-711 and MS713 main body is accurately controlled at a stable temperature in order to provide the best performance in a wide operating temperature range. The rugged optical design of the diffusor and input optics make the MS spectroradiometer series concept superior to any fiber optic spectroradiometer which will be susceptibel to mechnical vibration and handling. The MS spectroradiometer series are designed for permanent installation, but are perfectly suited as a traveling reference.

Both spectroradiometers have a separate power supply and can be controlled through RS232 / 422 by a PC or data logger. The PC software provides different functions for operating, data management andvisualisation. Software can also be customized to the individual user purpose by making use of the existing system control functions through the open command protocol.

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-711 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.
