Desktop Scanning Electron Microscopy

Jeff McGinn

How can a desktop SEM enhance your workflow?

Scanning electron microscopes (SEMs) produce high resolution, high magnification images by scanning the surface of a specimen with a focused beam of electrons. Developed in the 1930s, these exciting microscopes have changed significantly over the years in size and capability. Earlier SEMs typically required special rooms with dampening equipment to alleviate magnetic fields, vibrations, temperature variations, etc. Some modern-day SEMs require special laboratory designs in order to achieve high-performance electron microscopy.

Desktop SEMs were developed over 15 years ago and have come a long way since they were introduced. With capabilities including magnifications over 100,000X, multiple accelerating voltages, and both secondary (SED) and back-scattered electron (BSE) detectors, these smaller versions of full-size SEMs have found their way into more and more industrial and educational laboratories. They require less space, no special lab design, and the operator can be trained in less than 30 minutes. They serve as great teaching tools within academia, and can be used in biological, materials, and forensic science applications.

At McCrone Microscopes & Accessories, we offer the JEOL JCM-7000 to our clients. Equipped with a large sample chamber, high and low vacuum modes of operation, both secondary and backscatter electron detectors, real-time 3D imaging, easy to use metrology tools, and fully-integrated energy dispersive X-ray (EDS), the JCM-7000 NeoScope is smart, flexible, and powerful. And with magnifications up to 100,000X you’ll see what you’ve never seen before. Check out some of these amazing images captured with the JCM-7000 desktop SEM!
