Laser Wavelengths

Electromagnetic Spectrum colors, wavelengths, and sizes

This chart shows colors of the visible light spectrum, and the associated wavelengths in nanometers.

Traditionally, the ranges of each spectrum are ultraviolet light (100-400 nm), visible light (400-750 nm) and infrared (750 nm-1,000 nm).
