Preface

Abstract

The NEWRAD Conferences bring together participants from National Metrology Institutes (NMIs) and key user communities in advanced radiometry. The 15th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2023) was held at the National Physical Laboratory (NPL) in Teddington, UK, from 11th to 15th September 2023. The confernce was organised by NPL’s Optical Radiometric Metrology (ORM) group, who also handled abstract submissions and website administration. The NEWRAD 2023 conference saw 143 registered participants, with a total of 129 papers presented. Among these, 41 were oral presentations, complemented by 7 invited talks. Additionally, 88 posters were showcased during breaks and dedicated sessions, sparking lively discussions and idea exchange. The NEWRAD 2023 conference proceedings comprise contributions from the conference presentations. The submitted papers underwent peer review following the procedures of the Journal of Physics: Conference Series. I wish to thank the diligent reviewers and the dedicated editorial staff at the Journal of Physics: Conference Series for their meticulous work in facilitating the publication of these proceedings. I also wish to thank Nicole George, Dan Moore, Roger Hughes, Paris Aitken-Smith, and the entire organizing teams at NPL for hosting an exceptional conference. Finally, I want to express sincere appreciation to the NEWRAD scientific committee, who diligently reviewed and selected all the abstracts submitted to the conference, and provided unwavering support in organizing this event. Undoubtedly, this issue will serve as a valuable reference for radiometry. The venue of the next NEWRAD Conference is being organised and will be announced very shortly.
