The sunlight spectrum roughly covers a wavelength of 220–2,500 nm. It mostly consists of UV light (ranging from 250–400nm), visible light (between 400–750 nm) and near infrared light (NIR) with a range of 750–2,500 nm. Most important for daily life is visible light, because its interaction with matter allows the human eye to perceive text, image and colour.
