The topical meeting (TOM) on Optical System Design, Tolerancing and Manufacturing will highlight significant technology trends, emerging technologies and associated prospective developments in the field of optics design, tolerancing and fabrication. This TOM provides a forum for all aspects of optics design and fabrication, ranging from micro to large-scale optics and from high value one-off to mass-produced components including lessons learned papers on special design and manufacturing issues; also including the varieties of high quality optical coatings addressing materials, deposition methods and laser-induced damage threshold testing. One main goal of the meeting is to provide a better link between the design, the manufacturing, and the characterization of optical components and systems. Consequently, special attention will be paid to the collaboration between design and fabrication to generate cost-effective and manufacturable optical systems.
