GAITHERSBURG, Md., April 29 -- The National Institute of Standards and Technology (NIST) has developed a "rainbow source" that can be tuned across the entire visible light spectrum, from red to blue light. This unique source exploits recent materials advances in LEDs of different colors. By mixing exact percentages of LEDs at different wavelengths of visible light with the desired brightness, the optical properties of the source (such as the color) can be changed and tailored for a particular application.
