On behalf of the conference committee, we sincerely welcome you to the workshop titled “Ultra Precision Manufacturing of Aspheres and Freeforms – Imaging and Non-imaging Applications” (UPM Workshop 2017). UPM 2017 will be held in Changchun, China, from September 24 to 26, 2017, co-organized by the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences (CIOMP) and the Fraunhofer Institute for Applied Optics and Precise Engineering (IOF), Germany.

UPM workshops bring together scientists, manufacturers and vendors in a collaborative and informative environment. Traditionally, the workshops were hosted every two years in Germany by Optonet and the Fraunhofer IOF. The 2017 workshop is the first UPM workshop to be held in China and builds upon the foundations of previous events in Germany. We are happy to announce that future UPM workshops will be held annually at IOF in even-numbered years and at CIOMP in odd-numbered years to encourage and enhance broader communication and international cooperation.

I hope you will enjoy the talks as well as the social events and take the workshop as a great opportunity to establish collaborations and exchange ideas with colleagues all over the world. Have a wonderful time in UPM Workshop 2017 in Changchun!
