Welcome to, a collection of helpful resources for students, educators and researchers involved with photonics, the technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon.

DICTIONARY+ > Photonics Dictionary® Plus Definitions of photonics technology terms, abbreviations and acronyms. It is in the form of a wiki, so the content can be edited and expanded by members of the photonics community – including you!
Contains videoconverging lens
Also known as convergent lens or convex lens. A lens that converges an incident bundle of rays to a focus.

HANDBOOK > Photonics Handbook® A unique collection of technical design and applications articles, as well as articles presenting the basics of photonics technology. Topics range from detectors, cameras and imaging to optical components and positioning equipment and much more.
Cleaning Optics
Contamination is a Dirty Word
Cleaning optical elements improves performance, providing proper materials, techniques and handling procedures are used to minimize the risk of damage. If you wear glasses or drive a car you know the detrimental effects of dirt on the performance of a lens or window. The effects can be more serious in optical setups that involve laser radiation. Contaminants, whether on a coating or on the substrate surface, absorb laser energy and can damage the coating or its interface with the substrate....
