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 on 16 May and provides various resources to help create an event.


   •  Update your social media platforms with SPIE IDL Social Media Graphics featuring our 2018 SPIE IDL Photo
      Contest participants. SPIE has created Facebook cover photos, LinkedIn banners, and Twitter header photos
      that will inspire your followers.

   •  Demonstrate the science of light with lessons included in our SPIE IDL Outreach Activities Collection.
      New for 2019 there is a Microscopy lesson (English only) and a Polarized Light Art lesson (watch the video
      instruction in English, French, and Spanish)

      With the help of our SPIE Student Chapters and other volunteers, lesson plans have been translated into
      other languages. You can download these new lessons with our original offerings in the following files:

        • English Lesson Plan Worksheets

        • French Lesson Plan Worksheets

        • Simplified Chinese Lesson Plan Worksheets

        • Spanish Lesson Plan Worksheets

        • Diffraction Glasses Lesson in Hindi

        • Magic Water Lesson in Armenian

   •  Explain the International Day of Light with the SPIE IDL PowerPoint presentation or Fact Sheet.

   •  Distribute SPIE IDL Bookmarks featuring images from the 2018 SPIE IDL Photo Contest.

   •  Hang SPIE IDL Banners that feature the winners of the 2018 SPIE IDL Photo Contest.

   •  Print the 2018 SPIE IDL Poster (available in Spanish as well) and our new 2019 SPIE IDL Poster. Or print
      these four-poster series, one that answers What Is Light and one that shows how light addresses the
      UN's Sustainable Development Goals.

   •  Put the IDL Logo, designed by SPIE and available in 33 languages, on your communications.
