On 21 October 1983, the General Conference on Weights and Measures adopted value for the speed of light.

On the occasion of this anniversary, every year hundreds of activities are voluntarily organised over around the world. The purpose is to promote photonics and inform the general public on what are photonics technologies, why they are important, and generally support this key-enabling technology.

Baltic Photonics Cluster invites You to be part of activities related to the day of photonics 2020: either take part in relevant webinars or organize an event to promote photonics around 21st of October 2020.
