Chinese show grows to new heights

14 Sep 2005

CIOE 2005 reaches the size of Photonics West in the US with two large halls packed full of exhibitors.

The annual China International Optoelectronics Expo (CIOE) is fast becoming one of the largest photonics trade shows in the world. According to organizers Wen Global Solutions, last week’s four-day event in Shenzhen involved 1600 companies, occupied 60,000 m2 and is 30% larger than last year.

Optics.org’s analysis of the floorplan and the event catalogue estimates that the actual exhibitor number was a more modest figure of between 700 and 800. However, this still means that CIOE is about the same size as this January’s Photonics West in the US (750 exhibitors) and not that much smaller than the giant LASER World of Photonics show in Germany which takes place every two years and attracted 950 exhibitors this June.

CIOE 2005 was divided up into two halls and four zones: optical communications (157 booths); international exhibitors (95 booths); optoelectronic displays and LEDs (156 booths); and optics and lasers (272 booths).

Highlights of this year’s show include a large number of domestic makers of LED displays for signage and advertising as well as suppliers of optics for DVD/CD players and cameras. One entire section of the show was also devoted to modules and equipment for optical communications.

Although many exhibitors were focused on large volume, consumer markets, there were several specializing in laser crystals and other scientific instruments such as positioning equipment.

The show is also starting to attract an increasing number of well-known US and European firms. According to the organizers, 30% of the firms attending were from outside China and Coherent, Edmund Optics, Corning, Schott, New Focus, nLight and Instrument Systems all had their own booths. There was also a French pavilion which was hosting about a dozen firms including Imagine Optic, Varioptic and Thales Laser Diode.

The show did not feature a detailed technical conference, instead firms were giving brief presentations on their products in a press room.
