Commencement ceremony

Congratulations on your graduation and best wishes for your future!


The 1st Research Report Meeting of Optics Education and Research Center was held

We reported the research results in four projects: "Smart Manufacturing Optics", "Smart ICT Social Optics", "Real-World Information Optics", and "Natural Environment Optics". The purpose of these projects is to form a base for the creation of research areas that can lead Japan and the world in the field of optics.Thank you very much for your participation.
