Watch Integrated CLEM system SECOM live in action

August 06, 2019

In May we organised the first online live demonstration of our cathodoluminescence system, SPARC. It was a great way to show the possibilities of the system. We are excited to announce that at the end of this month, on the 27th of August, we are planning to have an online demonstration of the SECOM system, our integrated correlative light and electron microscope.

Vast possibilities of SPARC cathodoluminescence detector

July 09, 2019

SPARC Spectral is the most flexible and reliable cathodoluminescence system on the market, allowing experimental freedom thanks to its modularity. The possibilities of this system are vast: six imaging modes, open-source software ODEMIS and modular design ensure this. This system is successfully used by companies and research institutes all over the world in the fields of nanophotonics, materials science and geosciences (read our customer stories in our blog).

Cathodoluminescence used to measure mode alignment in inversely tapered silicon nano-resonators

July 02, 2019

A new paper on inversely tapered silicon nano-resonators by researchers from the Helmholtz-Zentrum Berlin and Freie Universität Berlin was recently published in Scientific Reports. In their study the authors selectively excited and measured the optical modes of inversely tapered silicon photonic resonators using cathodoluminescence spectroscopy. This allowed them to experimentally map the whispering gallery modes(WGMs) in such photonic resonators.

Cathodoluminescence for plasmonics: webinar

June 18, 2019

We are continuing our educational series of webinars, dedicated to cathodoluminescence technique and its application in different fields. Over the last few months, we have covered cathodoluminescence for geology, rare-earth materials, as well as time-resolved cathodoluminescence and lens scanning energy-momentum CL. On the 11th of July we are going to focus on yet another field, where cathodoluminescence can be successfully used: plasmonics

Request an online demonstration of SPARC

May 28, 2019

In May we performed the first online live demonstration of the SPARC cathodoluminescence system. It was a great opportunity for those who wanted to learn more about both hardware and software of the system. 

During the demonstration our Product Manager Toon Coenen briefly explained the principles of cathodoluminescence and a few imaging modes. After that, he showed the system and talked about the hardware: detectors and optical modules. The rest of the demonstration was dedicated to looking at the geological samples and acquiring images with intensity mapping, hyperspectral and angle-resolved cathodoluminescence.

Energy-momentum cathodoluminescence imaging used for probing topological silicon photonic lattices: new paper

April 23, 2019

The new paper, which was published in Physical Review Letters, studies two-dimensional hexagonal photonic lattices of silicon Mie resonators with a topological optical band structure in the visible spectral range. The local optical density of states is mapped with deep subwavelength resolution, and the results show evidence of topological edge states at the domain walls between topological and trivial lattices.

Wavelength and angle-resolved (energy-momentum) cathodoluminescence explained in a technical note

April 17, 2019

In order to explain the possibilities of energy-momentum cathodoluminescence technique we prepared a technical note, which is now available for download. This technique, also known as wavelength and angle-resolved cathodoluminescence (WARCL), combines“conventional” angle-resolved CL imaging with hyperspectral CL imaging. Energy-momentum imaging approach opens up new ways for studying optical properties of(nano)materials in wavelength/energy and angle/momentum space in great detail.
