--- title: New energy-momentum cathodoluminescence technique explained in the upcoming webinar description: The upcoming cathodoluminescence webinar is dedicated to spectrally and angle-resolved imaging technique, also known as energy-momentum cathodoluminescence. Join the webinar to learn about the principles of this technique and how it can be used in the fields of nanophotnics and plasmoncs. image: https://blog.delmic.com/hubfs/Energy-momentum%20webinar-1.png --- ###### [cathodoluminescence](https://blog.delmic.com/news/topic/cathodoluminescence), [nanophotonics](https://blog.delmic.com/news/topic/nanophotonics), [webinar](https://blog.delmic.com/news/topic/webinar) • 1 # New energy-momentum cathodoluminescence technique explained in the upcoming webinar [Delmic April 4, 2019](https://blog.delmic.com/news/author/delmic) ![Energy-momentum webinar-1](https://blog.delmic.com/hs-fs/hubfs/Energy-momentum%20webinar-1.png?width=1080&name=Energy-momentum%20webinar-1.png) We are excited to announce that we are preparing the first webinar dedicated to spectrally and angle-resolved cathodoluminescence, an imaging technique also known as lens-scanning energy-momentum (LSEK) cathodoluminescence. This unique technique allows acquiring hybrid multidimensional high-resolution angle-resolved hyperspectral datasets. To put it simply, it uses the principle of angle-resolved imaging but allows users to acquire high resolution datasets both in angle and wavelength, for any given location on the sample. The data gained with energy-momentum cathodoluminescence can be particularly beneficial in the fields of nanophotonics and materials science.  During the webinar Toon Coenen, our Product Manager and one of the authors [of a recent paper](https://pubs.acs.org/doi/10.1021/acsphotonics.8b01711) describing energy-momentum cathodoluminescence for studying plasmonic bullseye antennas, will talk about: - fundamentals of angle-resolved cathodoluminescence imaging - principles of spectrally and angular-resolved CL imaging - possible applications in the fields of nanophotonics and materials science - studying plasmonic bullseye antennas with energy-momentum CL Register for the webinar below. Even if you won't be able to attend, you will receive a post-webinar recording. #### Delmic [![](https://blog.delmic.com/hs-fs/hubfs/HER2--1.png?width=380&name=HER2--1.png) ](https://blog.delmic.com/news/delmics-vem-webinars-2026-nanoscale-3d-cellular-atlases) [###### life sciences ## Delmic vEM Webinars Session 2026: Nanoscale 3D Cellular Atlases Nanoscale 3D Cellular Atlases: Novel Insights into Organelle Interactions Illuminating Cellular Mechanisms ](https://blog.delmic.com/news/delmics-vem-webinars-2026-nanoscale-3d-cellular-atlases) [![](https://blog.delmic.com/hs-fs/hubfs/Website%20Content%20Offers/Webinars/Webinar%20Thumbnails/2024_In-Tissue-Cryo-ET_Webinars_Resources_270px.png?width=380&name=2024_In-Tissue-Cryo-ET_Webinars_Resources_270px.png) ](https://blog.delmic.com/news/delmics-first-cryo-et-online-symposium) [###### life sciences ## DELMIC's Cryo-ET Online Symposium 2025 DELMIC Cryo-ET Online Symposium 2025 brings to you 7 expert speakers from the cryo-ET field.
