The ILT490 International Light Profiling Belt Radiometer is an advanced instrument designed for measuring the intensity distribution of solar radiation in the ultraviolet (UV), visible (VIS), and near-infrared (NIR) regions of the electromagnetic spectrum. This radiometer is specifically engineered for use in solar energy research, photovoltaic performance testing, and environmental monitoring applications.
The ILT490 features a light profiling belt design, which allows for the simultaneous measurement of solar radiation at multiple wavelengths along a horizontal or vertical axis. This design is particularly useful in studying the spatial distribution of solar radiation, such as in cloud shadows, atmospheric layers, or solar panels.
The radiometer is equipped with a high-sensitivity photodetector array, which enables accurate measurements of solar radiation intensities as low as 0.1 W/m . The array consists of 64 individual photodiodes, each sensitive to a specific wavelength range, providing a comprehensive spectral coverage from 280 to 1100 nm.
The ILT490 is also equipped with a built-in data logger, which stores up to 100,000 measurements. The data logger allows for easy data transfer to a computer via a USB interface, and provides various data output formats, including ASCII and CSV.
The radiometer is designed to be highly portable, with a compact and lightweight construction. It is also weather-resistant, with a rugged enclosure that protects the sensitive components from dust, water, and other environmental factors.
In summary, the ILT490 International Light Profiling Belt Radiometer is a powerful and versatile instrument for studying the spatial distribution of solar radiation. Its high sensitivity, wide spectral range, and portable design make it an ideal tool for solar energy research, photovoltaic performance testing, and environmental monitoring applications.
