COTECH

"Coatings for Optical, Electronic and Chemical Industries (COTECH)"

EPET II 333 (1/95-12/98)
Coordination by LTFN
Project Coordinator: Dr. S. Logothetidis, with the participation of five industries

The project's aims are summarized as following :

  • Growth of multilayered optical coatings, consisting of dielectric materials, on substrates of glass and plastic ophthalmic lenses: Antireflective (AR) or High Reflective (HR) in the VIS and NIR energy region
  • Comprehensive characterization of the surface and bulk properties of quartz crystals used in telecommunication industry. Optimization of quartz blank metallization process by using new deposition techniques (e.g. sputtering) and new metallic coatings (e.g. Ti films). Design of a modular high vacuum system (HVS) with magnetron sputtering deposition technique and in-home manufacture of its automatic control. Implementation of HVS in production line
  • Growth of DLC films rich in sp3 bonds using magnetron sputtering, as protective films on AR optical systems and testing of their mechanical and environmental stability
  • Development and characterization of thick wear-resistant multi-coatings using plasma spraying technique for protection and increase the performance of turbines (rotors and bearings) which are used in the production line of chemical industries
