Founded in 1916, The Optical Society (OSA) was organized to increase and diffuse the knowledge of optics, pure and applied; to promote the common interests of investigators of optical problems, of designers and of users of optical apparatus of all kinds; and to encourage cooperation among them. The purposes of the Society are scientific, technical and educational.
The Optical Society brings together optics and photonics scientists, engineers, educators, and business leaders. OSA's membership totals more than 17,000 individuals from over 100 countries. Approximately 52 percent of the Society's members reside outside the United States.
