14th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2021)

NIST is closely monitoring guidance from Federal, State, and local health authorities on the outbreak of COVID-19. To protect the health and safety of NIST employees and the American public they continue to serve, NIST has decided to postpone indefinitely. The rescheduled dates are 21 Jun - 24 Jun 2021.

On June 21-24, 2021, NIST will hold the 14th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2021).

The NEWRAD Conference covers all aspects of optical radiation measurements and a wide range of topics will be presented during our four day program, including Earth remote sensing observations and Quantum optics technologies. Individual sessions will be devoted to these specific themes. In addition to an ambitious presentation schedule, there will be opportunities to visit nearby institutes that we hope to be of interest to all participants.
