  2. Transmission Electron Microscopy (TEM) Sample preparation

    Sample preparation in Electron Microscopy is one of the most important factors in obtaining high quality data. A key phrase to remember is if you put “rubbish in” you’ll get “rubbish out”. Therefore, how can high quality TEM samples actually be produced? This short article will try and answer this question by covering the basic steps of sample preparation for...

  5. How to Save Time When Testing Multiple Cable Types

    Changing out reference cables during the insertion loss and return loss testing process to accommodate new DUT types can cause downtime for a manufacturing line and drastically reduce the efficiency of the cable production process. With single channel DUTs and reference cables, the issue may seem inconsequential. However, in the modern fibre production line every minute counts; any method that...

  6. How a microfabrication researcher uses SEM as a technique to verify nanoscale structures

    Microfabrication, the creation of microscale structures and features, is an essential technique for the creation of next-generation semiconductors, processors and the ‘lab-on-a-chip’ microfluidic systems found in chemical analysis systems that can fit in the palm of your hand. Until now, microfabrication has relied on masking techniques such as lithography, which limits the variety of structures that can be produced. However...

  7. FEG vs. Tungsten source in a scanning electron microscope (SEM): what’s the difference?

    After few years of operating a transmission electron microscope (TEM) in my postgraduate studies, in 2006 I started my career in electron microscopy as an SEM operator for a biological and medical research centre in York (United Kingdom). Not knowing how to operate an SEM before, I found it relatively easy to switch from TEM to SEM. My first SEM—equipped...

  8. SEM: types of electrons, their detection and the information they provide

    Electron microscopes are very versatile instruments, which can provide different types of information depending on the user’s needs. In this blog we will describe the different types of electrons that are produced in a SEM, how they are detected and the type of information that they can provide. As the name implies, electron microscopes employ an electron beam for imaging...

  10. How to spot astigmatism in Scanning Electron Microscopy (SEM) images

    You may have heard of astigmatism as a medical condition that causes visual impairment in up to 40% of adults , but how is this applicable to electron microscopy? First of all, let’s talk about what the word astigmatism, in fact, means: It is derived from the negative prefix ‘a’ (without) + ‘stigmat-’ (mark, or point, in Ancient Greek...
