Founded in 1955, SPIE is a renowned professional society dedicated to the research, engineering and application of optics, photonics, optoelectronics and imaging, aiming to promote the application of optical technology in various interdisciplinary disciplines, and is the most authoritative institution in the field of optics and optoelectronics in the world today. The Institute is composed of 180,000 leading professionals from more than 170 countries and regions around the world and hosts 25 international forums and exhibitions each year in North America, Europe, Asia and the South Pacific.

The Western Optoelectronics Exhibition is the largest optical trade fair in North America sponsored by the International Optoelectronics Engineering Association of the United States, and is also one of the world's best known exhibitions in the optoelectronics industry, including the biomedical optoelectronics exhibition SPIE BiOS Expo, laser application technology exhibition, micro and nano technology exhibition, pan-optoelectronics technology exhibition and other theme exhibitions.

In the Western Optoelectronics Exhibition, Asian enterprises, especially Chinese enterprises, have become the most significant group of exhibitors. Relying on the geographical advantages, technological advantages and popularity advantages of Silicon Valley in California, the exhibition has been steadily developing since its inception, and the development in recent years is even more remarkable. Technology, trend and innovation become the attraction and value of the exhibition. Here you can come face to face with more technology and advanced technology. Another reason why this exhibition attracts many high-end professionals every year is that a number of academic exchanges sponsored by SPIE will also be held in the same period, and the academic atmosphere is better than other similar exhibitions in the world.
