Cathodoluminescence imaging on quartz in sandstone

Spectrally and angular-resolved cathodoluminescence explained

What is spectrally and angular-resolved(also known as energy-momentum) CL?

In the last blog post we explained angle-resolved cathodoluminescence imaging, a technique which is used to acquire angular profiles and gain a better understanding of materials' optical properties. The imaging technique that we are focusing on this week combines information acquired with angle-resolved imaging and high-resolution spectroscopy. This technique is called Lens-scanning energy-momentum(LSEK) Imaging, or full Angle-Resolved Spectroscopy, and it allows collecting a full emission spectrum for each emission angle. This new imaging technique is now available with the SPARC system. Keep reading if you would like to understand how it works and what results can be achieved.

6 imaging modes of cathodoluminescence detector

Posted by Delmic on Feb 27, 2019 2:18:00 PM

Cathodoluminescence is a great tool for obtaining valuable information about the properties of a sample. This data can help researchers and developers get a better understanding of possible defects, efficiency of the material and other properties. 

The SPARC cathodoluminescence detector has 6 imaging modes which can enhance your research and provide you with an important information about your samples. Keep reading if you would like to know what exactly is possible with these modes!
