The 20th and 21st centuries were truly phenomenal for technological advances, particularly in the fields of light sources and laser manufacturing. During this period, we have been introduced to a variety of unique light products that have considerably enhanced the functioning of several other types of equipment used in various industries such as medical, electronics, and robotics. Broadband light sources are light sources that produce light across a wide range of wavelengths, as opposed to monochromatic light sources, which produce only a single wavelength or color of light. Broadband light sources are extremely useful since they emit a wide range of light wavelengths. We may then use the monochromator to select the exact color we require for our application. That is the fundamental introduction or definition of a broadband light source.
