Why SEM is the most suitable microscopy technique for fiber analysis

By Karl Kersten - Sep 1, 2017

Fibers are all around us. Different types of fibers exist, but in most cases we do not notice them because they are used in a product. In case an object is much longer as it is wide we consider it a fiber. Fibers have specific properties for the product in which they are used. This blog will describe the different ways how these fibers can be classified and how their performance can best be analysed. Hint: it has something to do with putting fibers under a specific type of microscope. You're about to discover the most suitable microscopy technique for fiber analysis, so do read on!

Desktop SEM electron sources: why CeB6 is the right choice

By Karl Kersten - Aug 3, 2017

If you’re looking for a scanning electron microscope (SEM), you probably know by now that the electron source is one of the most important parts of the system. In a previous blog, we talked about the properties of three different electron sources: the Tungsten, CeB6 and FEG sourcesIn this blog, we’ll take a closer look at Tungsten and CeB6 electron sources.

Is a desktop SEM the best choice for my application?

By Karl Kersten - Feb 9, 2017

You know you need more SEM capability. Maybe you have a traditional floor model SEM, but it is slow and complicated to operate. Maybe you are using an outside service and the turn-around time is unacceptably long. You’ve made your case that your company could significantly improve their business performance and you could do your job better if SEM imaging and analysis were easier, faster and more accessible. Can a desktop SEM do what you need?

How this engineering company supercharged their R&D process

By Karl Kersten - Dec 9, 2016

As device dimensions are shrinking, researchers are required to work on nanoscale levels. As a result, new technology is needed to create and evaluate structures. Luckily in turn, the physical size of this technology is getting smaller too.

STOP outsourcing your SEM work — get your personal SEM!

By Karl Kersten - Oct 4, 2016

Are you a lab operator who wants to stop outsourcing and buy your own Scanning Electron Microscope? Then you’ve probably already calculated that a personal SEM is a worthwhile capital investment. But the operational costs are just as important too: all the ongoing equipment expenses related to an SEM like the facilities, its maintenance, and operators.
