Unlike traditional chemical dyes, physical pigments achieve their hues by directly manipulating light waves. They are being actively pursued by the printing and packaging industries, for decorative purposes, and in transportation and security.by Faiz Rahman and Nigel P. Johnson
The mathematical studies done by Edmond Nicolas Laguerre in the 19th century laid the foundation for contemporary optical communications.by Mario Martinelli and Paolo Martelli
This month’s edition of the journal Applied Optics is a special issue devoted to the contributions of the late Emmett Leith. As a tribute to his dear friend, the author discusses the significance of Emmett’s work and his own role in inventing computer-generated holography.by Adolf W. Lohmann

Mysterious photos taken by lightning. Perfectly preserved images captured on the retina of a dead man’s eye. Are these bizarre phenomena grounded in fact or examples of science fiction?
Stefan Sydor Optics was founded in 1964 as a small manufacturer of all types of optics. Since then, it has grown in size but narrowed in scope to become a leading producer of precision, flat-surfaced, parallel and wedged optics.
Our conversation with Rep. Bart Gordon (D-Tenn.)
An interesting type of accelerating wave packet—a theoretical prediction made nearly three decades ago—has now shown up in laboratory experiments.
Local sections have always been an important part of the Optical Society. In fact, OSA itself began as a local section.
A group of researchers from the Wellman Center for Photomedicine built a flow cytometer that can trace fluorescently tagged cells through the blood vessels of a mouse retina.
