The focus of this topical meeting will be to explore and discuss new trends and developments within the fast evolving field of optical systems based on freeform optical surfaces as major component. Freeform optical components refractive as well as reflective offer great chances to realize non- or low-symmetry optical systems with new functionalities, high optical performance or reduced complexity.  This implies in particular to illumination systems and to optical systems with very special requirements such as in applications to augmented reality and virtual reality. On the other side the manufacturing, characterization, assembly and optical testing of such systems is especially for imaging systems still challenging. The topical meeting will address how new tools and technologies in design, manufacturing, and inspection are enabling next generation freeform optical systems and focuses on applications in illumination and imaging systems including augmented and virtual reality systems.

Topics include (but are not limited to)

  • Optical system design of imaging and non-imaging systems
  • Aberration theory, system simulation and surface representation
  • Tolerancing, alignment and assembly strategies
  • Manufacturing
  • Metrology
