Dear visitors,

Considering the success of the letter of Sizygies and at the request of numerous subscribers, we decided to create this dedicated site.

The letter of Sizygies was born in December, 1998. The letter is each season published, hence, its name of Syzygies*.

It is a free information letter, talking about the Fluid Optics' concept, which contains articles, on theoretical concepts, on products, on technical information or on news, in the field of the lighting, of the optics or the sciences.

This letter is also that of our subscribers. It can talk, on the demand of our subscribers, about scientific or technical subjects which can totally be without relation with the Fluid Optics.

Sometimes, in our pages, welcome companies or physical persons who present their new services, their new products or their realizations. In that case, the subscribers are directly got in touch with these persons or companies.

Thank you of your loyalty.

The Fluid Optics inventors.
