Title: The Innovative Journey of Dominique Bonvallot
Introduction
Dominique Bonvallot is a notable inventor based in Mulhouse, France. He has made significant contributions to the field of optics through his innovative patent. His work focuses on creating transparent articles with specific refractive index properties, which have various applications in the optical industry.
Latest Patents
Dominique Bonvallot holds a patent for a "Process for obtaining a transparent article with a refractive index gradient." This patent outlines a method that includes several key steps. The first step involves irradiating a crosslinkable liquid mixture of base photopolymerizable monomers, which is modulated spatially in intensity and/or irradiation time. This process forms a structure gradient according to a desired index profile until a self-supporting polymer matrix is obtained. The second step requires swelling the polymer matrix to thermodynamic equilibrium in a swelling composition containing a polymerization initiator and one or several polymerizable monomers. This results in a polymer with a different refractive index from the matrix obtained in the first step. Finally, the third step involves polymerizing the swelling composition that has diffused into the matrix homogeneously, thereby obtaining a transparent article with a refractive index gradient.
