Solar spectrum

What is Solar spectrum?

The total distribution of electromagnetic waves emitted by the sun. The wavelength range defines the solar spectrum regions. The visible light wavelengths range from around 390 to 780 nm. The region between UV (300 nanometers) to NIR (3 microns) contains around 99% of solar radiation. The total solar radiation, or broadband, combines radiation in the wavelength range of 280-4,000 nanometers.
