How Does the Photonic Curing Process Work?
Light energy incident on a body will be absorbed and heat up the object. The light-matter interaction determines what fraction of light is reflected back, transmitted through or absorbed by the body. The fraction of light absorbed can be guessed by the color of the body (darker material absorbs more light). Light that is absorbed by the body is mostly converted to heat and shows up as an increase in its temperature. That’s why wearing a black shirt in the middle of a Texas summer isn’t the most comfortable thing to do.
