Spectrafy - Model SolarSIM-UV -UV Irradiance Sensor
The SolarSIM-UV brings our SolarSIM technology to bear on the challenge of solar UV measurement. The result is a UV sensor like no other.
The SolarSIM-UV uses multi-spectral measurement to accurately resolve the solar spectral irradiance over the full UV range. From this, all the UV components are then precisely extracted.
- Measurands: UV-Total, UV-A, UV-B, UV-E, UV index, PAR, GHI
- Technology: Software-augmented multi-filter radiometer.
- Highlights: All UV components from a single sensor. UV spectral and total irradiances.
Measuring solar UV irradiance is tough. The SolarSIM-UV rises to the challenge through the use of multi-spectral measurement. The result is a robust, accurate UV sensor unlike anything else.
The SolarSIM-UV uses filtered photodiodes to make precise, multi-spectral measurements of the solar spectrum in several narrow wavelength bands. These measurements then inform Spectrafy’s proprietary algorithms to accurately resolve the global solar spectrum within the UV range.
The SolarSIM-UV software then automatically integrates and processes the UV spectral irradiance to provide the full suite of UV parameters, including UV-T, UV-A, UV-B, UV-E and UV index. Because the UV components are obtained directly from spectral integrals, the limitations associated with traditional UV sensors , such as imperfect filter profiles and spectral selectivity are eliminated.
This innovative approach makes the SolarSIM-UV the first, and only sensor capable of resolving all UV components at the same time, thereby greatly simplifying the sensor count required for comprehensive UV monitoring.
Applications for the SolarSIM-UV include weather forecasting, UV reporting for public health, ground truthing of climate models, agricultural monitoring and material testing.
