Members

The EOS has more than 5000 societal, corporate, individual, associate and student members. Read on to learn more about the structure of the EOS and find out how to join the growing European optics and photonics community.

Societal members

Currently, nineteen national optical societies in Europe are members of the EOS. There are two groups of EOS societal members:

EOS Branches:
So far, eight societies have opted for the status of an EOS Branch, thus making their members automatically full individual members of the EOS, too. These members are individual members through EOS Branches and are entitled to all EOS membership benefits.

The EOS Branches are:

• DGaO (Germany)
• SFO (France)
• IOP Optical Group (UK and Ireland)
• LAS (Russia)
• SSOM (Switzerland)
• SOS (Sweden)
• SIOF (Italy)
• HOS (Hungary)

EOS Affiliated Societies:
At the moment, the EOS has eleven Affiliated Societies. The members of these societies are automatically associate members of the EOS, but have fewer benefits than the individual members through EOS Branches.

The EOS Affiliated Societies are:

• FOS (Finland)
• NPS-OD (Norway)
• DOPS (Denmark)
• DPS-OS (The Netherlands)
• Promoptica (Belgium)
• CBO-BCO (Belgium)
• SEDOPTICA (Spain)
• PPS-OD (Poland)
• ROS (Romania)
• CSSF (Czech and Slovak Republic).

Corporate members

The EOS has about 45 member companies and research institutes. Read more about the benefits for corporate members.

Individual members

Every individual who is involved in optics and photonics may join the EOS and take advantage of the membership benefits.

Individual members through EOS Branches

Every member of an EOS Branch is automatically an individual member of the EOS with all benefits. Check the overview map to find out if your national optical society is already an EOS Branch.

Student members

Every student involved in optics and photonics may join the EOS as a student member with full benefits.

Associate members

Every member of an EOS Affiliated Society is automatically an associate member of the EOS, but with limited benefits. Check the overview map to find out if your national optical society is already an EOS Affiliated Society. It is possible to upgrade the associate membership to an individual EOS membership with full benefits.
