5 Near Infrared Components of Common Light Sources

Spectral plots show the amount of power that is radiated at each wavelength. Different light source types can have different spectral plots because of the way the light is produced. This section discusses the illumination mechanisms of common light sources, as well as the corresponding spectral plots. Each spectral plot shows wavelength in nanometers on the x-axis and relative intensity on the y-axis. The y-axis has been normalized to the peak intensity, allowing each plot to be directly compared.

For more information on types of light sources, please refer to the Fundamentals of Light Sensing chapter in the Ambient Light Sensors video series.
