Understanding the Difference between Magnification and Resolution in Scanning Electron Microscopy
Microscopes have revolutionized our ability to observe and analyze the microscopic world with unprecedented detail. By enlarging our view of objects, or magnifying them, microscopes allow us to visualize a greater amount of detail and distinguish (or “resolve”) features separated by very small distances. The scanning electron microscope (SEM) has quickly become one of the […]

What Probe Liquid Should You Use for Contact Angle Measurements?
Contact angle is defined as the angle formed by a liquid at the three-phase boundary where the liquid, solid, and gas intersect. It gives a fast, quantitative measure of a surface’s wetting properties. These properties can give insight into a solid surface’s interaction with liquids, such as its adhesion with a coating or its biocompatibility with bodily fluids. Contact angle measurements are used in a wide variety of applications, including evaluating surface cleanliness, characterizing functional coatings, and assessing surface treatments.
Thermionic vs. Field Emission Sources: 4 Key Differences
The electron source is one of the most critical components of a scanning electron microscope (SEM) because it determines the quality, brightness, and size of the electron beam used for imaging. The characteristics of the electron beam will influence the overall imaging capabilities of the SEM. Two common types of electron sources used in SEMs […]

What’s the Difference Between SEM & TEM?
Electron microscopy is best known as a high-powered microscopy technique that utilizes a beam of electrons as a source of illumination. In an electron microscope, a focused electron beam interacts with the sample surface, leading to various beam-sample interactions. Each interaction generates a distinct signal that can be utilized to produce a high-resolution image. Unlike […]
Why Use Low Accelerating Voltage for SEM Imaging?
Scanning electron microscopes (SEM) function by rastering a sample with a focused beam of electrons to produce high-resolution images of the sample surface. The generated signals from these sample-beam interactions are influenced by a multitude of factors, including the energy of the electron beam. The accelerating voltage, or the potential difference between the electron source […]
