The International Day of Light is a UNESCO global initiative to celebrate light and the role it plays in science, culture and art, education, and sustainable development and in fields as diverse as medicine, communications, astronomy, and clean energy. The event marks the anniversary of the first successful operation of the laser in 1960 by physicist and engineer, Theodore Maiman. There’s no better place to celebrate light than in Arizona with our world leaders in optics, photonics, and astronomy!
Explore and discover the world of optics and Arizona’s world leaders in the science of light!
