WISER II Spectroradiometer:

A spectroradiometer is a type of instrument used to measure the intensity of electromagnetic radiation across a wide range of wavelengths. The WISER II Spectroradiometer is a specific type of spectroradiometer that is designed for use in remote sensing applications. It is capable of measuring the solar reflectance and thermal emittance of materials in the laboratory and in the field, which can be used to determine the properties of the materials, such as their color, texture, and composition.

The WISER II spectroradiometer is a portable device that is lightweight and compact, making it easy to use in the field. It is equipped with a variety of measurement modes, including normal reflectance, hemispherical reflectance, and thermal emittance, which allows it to be used for a wide range of remote sensing applications.

The instrument is equipped with a spectral range of 300 – 2550 nm, and it can measure reflectance and emittance with high accuracy and precision. This allows it to be used for a variety of remote sensing applications, such as mapping the surface properties of the earth, measuring the health of vegetation, and monitoring the condition of buildings and other structures.

The WISER II Spectroradiometer can be used to measure reflectance and emittance in the laboratory, in the field, and even in flight. It can be easily configured to meet the specific needs of a given application. This instrument is made by Analytical Spectral Devices (ASD), has a history of being an industry leader in the field of spectroradiometry.

It also includes a variety of software tools for data analysis, such as a simple data visualization tool and a sophisticated data processing software that allows users to analyze their data and extract useful information. This software can be used to generate reflectance and emittance maps, as well as various types of indices that can be used to quantify the properties of the materials being measured.

Overall, The Wiser II Spectroradiometer is a powerful and versatile tool that can be used for a wide range of remote sensing applications. With its high accuracy and precision, it is a valuable tool for scientists and researchers working in the field of remote sensing, environmental monitoring, and materials characterization.

WISER II combines the MS-711 and MS-713 spectroradiometers to provide the most accurate outdoor solar spectral data. All-weather, with temperature-controlled spectrometers, the MS-711 and MS-713 deliver improved stability and long-term reliability. They are accurately calibrated with traceability to international standards and issued with a calibration uncertainty budget.
