SPIE International Day of Light Resources

SPIE IDL Resources

The International Day of Light is a global initiative highlighting to the citizens of the world the importance of light and light-based technologies in their lives, for their futures, and for the development of society. SPIE encourages communities to plan their own annual celebration of 16 May and provides various resources to help create an event.

IDL Bingo: Celebrate IDL2020 online this month by playing IDL Bingo with SPIE on your social media platforms - and be entered to win $500! Get your Bingo card and learn how to play.

Zoom Backgrounds: Now that many gatherings have moved online, SPIE has created 12 virtual backgrounds to help celebrate IDL2020 virtually. Download the series featuring photography from the 2019 SPIE IDL Photo Contest.
