MS-700N Spectroradiometer

A spectroradiometer is a device used to measure the spectral radiance or irradiance of a light source. The MS-700N Spectroradiometer is a specific model of spectroradiometer made by the company Ocean Optics. It is designed for use in a wide range of applications, including remote sensing, atmospheric monitoring, and industrial process control.

One of the key features of the MS-700N is its high sensitivity and wide dynamic range. It can detect light in the ultraviolet, visible, and near-infrared regions of the spectrum, with a spectral range of 350 – 1050 nm. The device is also equipped with a cooled, back-thinned CCD detector, which enables it to detect weak signals and achieve high signal-to-noise ratios.

The MS-700N also has a high spectral resolution, with a resolving power. This allows it to distinguish closely spaced spectral lines and accurately measure the intensity of light at different wavelengths. The device also has a high temporal resolution, with a measurement rate, which enables it to capture rapidly changing light conditions.

In addition to its technical capabilities, the MS-700N is also designed for ease of use. It has a compact and lightweight design, which makes it portable and easy to integrate into a wide range of measurement systems. The device also comes with user-friendly software, which allows users to easily control the spectroradiometer and process and analyze data.

In summary the MS-700N Spectroradiometer is a high-performance device designed for use in a wide range of applications. It offers high sensitivity, wide dynamic range, high spectral and temporal resolution, and easy operation and data analysis capability. It can be used in field of environmental monitoring, industrial process control, and laboratory research and so on.

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 350 nm to 1050 nm (visible-NIR).

The MS-700N is calibrated precisely and with traceability to International Standards, and it comes with a calibration uncertainty budget. The rugged optical design of the diffusor and input optics make the MS spectroradiometer concept superior to any fiber optic spectroradiometer, which will be susceptible to mechanical vibration and handling. The spectroradiometers are designed for permanent installation but are perfectly suited as a traveling reference.

The MS-700N has a separate power supply unit and can be controlled through RS232 or 422 by a PC or data logger. The PC software provides different functions for operating, data management, and visualization. Through the open command protocol of the defined system control functions, the software can be developed by the individual 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 the 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.
