Wavelength Conversion

Wavelength conversion is a physical process in optics where the frequency, wavelength, or spectral width of an incoming electromagnetic wave is modified into a different, specific light signal. In wearable phototherapy applications, this occurs when the internal patch substrate—composed of organic crystal matrices—intercepts the broad, scattered thermal energy emitted by human skin and converts it into stable, narrow, low-level light frequencies. This pure physical refraction matches the body’s natural energetic pathways without requiring synthetic chemical reactions or active electronics.
