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. May 16 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!

Optics and photonics are the science and engineering of light used everywhere, every day. Join us on May 21 to explore and discover the world of optics and Arizona’s world leaders in the science of light!

Attention teachers and students: This event is a great learning opportunity! Students attending can receive a "Certificate of Attendance" to provide to their teachers wishing to award credit. Ask for your certificate at the Optics Valley table!
