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.

Zoom Backgrounds, Mobile and Desktop Wallpapers: The new social media banners and cover images are here, depicting stunning photos from our 2021 SPIE IDL Photo Contest. And for our current virtual world, we have created Zoom Backgrounds for your online meetings as well as wallpapers for your desktop computer or mobile phone.
