Advancements in technology and innovative manufacturing processes are crucial for optical sector growth in today's global markets. Markets with high developmental momentum include the energy and semiconductor, life sciences, health care and the agri-food industries. Optical technologies play a crucial role in these markets, the importance of sophisticated but economically priced optical components being vital to new products and applications.

The 4th EOS Conference on Manufacturing and Testing of Optical Components, EOSMTOC 2015, will highlight significant technology trends, emerging technologies and associated prospective developments. This meeting provides a forum for all aspects of optics fabrication and testing, ranging from micro to large-scale optics and from high value one-off to mass-produced components including lessons learned papers on polishing process stability and finishing processes for high end optics as well as for optics featuring clear apertures below 1mm.

This time special emphasis is set to the topics Testing as well as Fabrication friendly Optical Design and Tolerancing groundwork for all successful manufacturing aspects.

Held in conjunction with the LASER World of PHOTONICS 2015 trade fair, one of the world’s largest for optics, it will be a unique opportunity for the exchange of information with renowned researchers, scientists, engineers and professionals from all over Europe!
