The twenty-third LASER World of PHOTONICS 2017 was held in Munich International Exhibition Center, Germany from June 26^th , 2017 to June 29^th. Changchun Institute of Optics, Fine Mechanics and Physics(CIOMP) and its affiliated companies enterprises under the strong support of the Jilin Provincial Department of Commerce and the Changchun Municipal Bureau of Commerce, participated in this exhibition in groups.

The attendees displayed a total of more than 40 products and technology in the exhibitions including CMOS image sensor, solid-state laser, semiconductor laser, grating ruler and photoelectric encoder, LED display with small spacing and multi finger fingerprint instrument, MOES series aircraft pod and high precision grating, filter, Aluminum Alloy beryllium metal mirror, ultra lightweight RBSiC mirror, photon counting imaging detector, Shack-Hartmann wavefront sensor and deformable mirror AMS3000, wide field stereo aerial system, high resolution CO2 optical detector, advanced manufacturing technology.

Munich international laser and Optoelectronic Technology Expo is one of the most professional optoelectronic exposition that covers all types of optoelectronics industry and exhibits the most advanced technology in more than 40 years. The exhibition presents photonic solutions, from components to systems, from specific applications to services, demonstrating and depicting the entire value chain of the industry, providing an important trading platform for global supplier buyers. By participating in this exhibition, CIOMP and its affiliated enterprises have achieved good international market promotion in the brand strength and high-tech photoelectric products.

Furthermore, prof. ZHANG Xuejun, as the Session Chair of the 5^th Conference on Manufacturing of Optical System which is a part of the EOS Conference, held the conference and made a presentation titled the Manufacturing large aperture and high diameter-to-thickness ratio flat mirror as the prototype of TMT M3.
