SPIE (formerly the Society of Photographic Instrumentation Engineers, later the Society of Photo-Optical Instrumentation Engineers) is an international not-for-profit professional society for optics and photonics technology, founded in 1955. It organizes technical conferences, trade exhibitions, and continuing education programs for researchers and developers in the light-based fields of physics, including: optics, photonics, and imaging engineering. The society publishes peer-reviewed scientific journals, conference proceedings, monographs, tutorial texts, field guides, and reference volumes in print and online. SPIE is especially well-known for Photonics West, one of the laser and photonics industry's largest combined conferences and tradeshows which is held annually in San Francisco. SPIE also participates as partners in leading educational initiatives, and in 2020, for example, provided more than $5.8 million in support of optics education and outreach programs around the world.
