15th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2023)

From 11 to 15 September 2023, The National Physical Laboratory (NPL) will host the 15th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2023) at our facilities in Teddington, (near London) UK.

The NEWRAD Conference covers all aspects of optical radiation measurement and continues the philosophy from its inception of providing an opportunity to build interfaces between the founding: remote sensing, solar and metrology communities as well as more recent quantum optics together with other novel and emerging applications. The four-day programme, will be structured to present both state of the art research and facilitate discussion between communities through a plenary only format and social program.  There will also be opportunities to visit nearby institutes that we hope will be of interest to all participants.

The conference ticket includes all the hospitality and refreshments for the conference, a welcome reception on Monday 11 September and the social activity which is a guided tour of Hampton Court Palace and the conference dinner at The King's Head in Teddington on Wednesday 13 September.

The closing date to register for the conference is 23:59 (UTC+1) on 14 August 2023.
