Allocate the top of the poster for the title and authors as stated on the submitted abstract. Tacks and tape will be available for the mounting of posters. If you have any questions or comments, please do not hesitate to contact us.


Proceedings are a very important part of ETOP. They are available through open access in the SPIE Digital Library and are a unique tool to spread the word about your research, initiatives and activities in education and training in optics and photonics.



  • Each speaker will have 12 minutes for talk, plus 3 minutes for questions.
  • Invited speakers will have 25 minutes for talk, plus 5 minutes for questions.
  • Start each talk on time. Do not start early. Wait until the assigned time, since others may come from different rooms to hear the talk.

  • Introduce the speaker(s) and title only.

  • Use the color-coded cards to indicate 3-minute, 1-minute, and end (0-minutes) countdown times.
  • If person continues, it is suggested to stand and begin to move to front of room, which usually works to help end the session. If person has continued past the 12/25 minute mark, it may result in no time for questions.
