New energy-momentum cathodoluminescence technique explained in the upcoming webinar

April 04, 2019

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.

Large-area hyperspectral cathodoluminescence for imaging spatially extended specimen

March 25, 2019

Cathodoluminescence imaging is a powerful tool for acquiring data from geological samples. Our new technical note describes in detail an acquisition mode called large-area hyperspectral cathodoluminescence imaging. Large-area(LA) spectral acquisition mode can be specifically used for imaging spatially extended specimen such as zircons and other minerals.

New paper establishes cathodoluminescence as an optical characterization technique with nanoscale spatial resolution

March 20, 2019

A new study, co-written by scientists from AMOLF and Delmic and published in ACS Photonics, investigates the factors that determine the spatial resolution of coherent cathodoluminescence as a deep-subwavelength imaging technique. This is done by examining nanoscale excitation of Ag nanocubes with coherent cathodoluminescence imaging.

Webinar: giant viruses under (correlative light and electron) microscope

March 05, 2019

If you are working in the field of biology, you probably know the struggle of combining electron microscopy imaging with light microscopy. Correlative light and electron microscopy(CLEM) is a powerful technique which makes it possible to combine the labelling power of fluorescence imaging with high resolution structural information acquired with electron imaging. This technique has been used for studying biological samples in the fields of marine microbiology, cancer research, neuroscience and, most recently, virology.

New study uses cathodoluminescence to characterize design of a plasmonic metasurface lens

February 19, 2019

A new interesting study on "Merging transformation optics with electron-driven photon sources" was published in Nature Communications. The research was done by scientists from the Max Planck Institute for Solid State Research in Stuttgart, AMOLF, and the University of Stuttgart. The study combines optical modelling and design of a plasmonic metasurface lens, with electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) experiments to characterize its properties. The experiments demonstrate that such surfaces can be used in the future for hybrid pump-probe experiments and/or spectral interferometry.

Advanced techniques and tool to study geological samples discussed during workshop in Oslo

January 24, 2019

On 16th and 17th of January the University of Oslo hosted the workshop "Analytical SEM for Geology" organized by Delmic, Hitachi and Bruker. 24 participants came from Norway, Poland, Denmark, Sweden and UK to learn about the most advanced techniques and tools for studying geological samples. The workshop, which lasted two days, included several presentations from invited speakers, as well as hands-on sessions on SEM equipment, which can be used to study and analyse geological materials. 

The first day of the workshop consisted of talks by Max Patzschke and Laurie Palasse from Bruker on the advanced microanalysis and characterization of mineralogical samples with electron backscatter diffraction (EBSD) and energy dispersive X-ray spectrometry (EDS). Tobias Salge from Natural History Museum of London presented his research on Macro, to Micro to Nanoscale Advanced SEM/EDS of Earth and Planetary Materials. Finally, Toon Coenen from Delmic talked abou

Energy-momentum cathodoluminescence technique applied to study plasmonic bullseye antennas

January 18, 2019

A new paper on "Energy-Momentum Cathodoluminescence Imaging of Anisotropic Directionality in Elliptical Aluminum Plasmonic Bullseye Antennas" was published in ACS Photonics by researchers Toon Coenen (Product Manager at Delmic) and Albert Polman (co-founder of Delmic and group leader at AMOLF). The paper for the first time introduces a completely new cathodoluminescence (CL) imaging technique called lens scanning energy-momentum (LSEK) cathodoluminescence.
