Development of the technology for the production of advanced anti-reflective and anti-scratch coatings on ophthalmic lenses - optical systems

PAVET Project. (2001 - 2003)
Coordination by LTFN
AUTh Sci. Responsible: Prof. S. Logothetidis

The aim of this project is to solve the durability problems that organic ophthalmic lenses with anti-reflective (AR) optical coatings exhibit, by modifying the deposition processes of AR coatings, as well as the anti-scratch process. This will be accomplished with the introduction of ion bombardment during the deposition of thin films consist the AR coatings (ion beam assisted deposition - IBAD) by using an ion gun of medium energies (~ 50-200 eV), which will be mounted onto the deposition chamber. By this it is expected to develop thin films having more tough structure and higher hardness, whereas an enhancement of adhesion between the several interfaces in AR coatings is also expected. With the proper modifications in anti-scratch process, which is in use today, it is expected the optimization of the properties of organic lenses, the improvement of their durability and lifetime.
