SNE-4500M Plus Tabletop SEM

Premium High Resolution Tabletop SEM (Scanning Electron Microscope)

The most advanced and full featured Tabletop SEM available incorporating a fully motorized 5-axis stage with navigation camera for easy sample positioning. The SNE-4500M Plus is the only tabletop SEM with a variable aperture providing similar resolution to full-size floor model systems with “live” magnifications up to 150,000X.  The EDS take-off angle has been improved from the prior model 10 degrees to an efficient 20 degree angle further increasing the systems ability for elemental analysis.

Additional features such as variable spot size control allow for the most flexible imaging as well as optimal x-ray generation for EDS analysis.  The SNE-4500M Plus comes standard with both Backscatter (BSE) and a true Everhardt-Thornley Secondary Electron (SE) detector as well as both standard high vacuum and a low (charge reduction) vacuum mode.  The 1 kV beam energy can be used to produce brilliant images of non-conductive biological samples even at high vacuum with NO sputter coating required.

The SNE-4500M Plus goes beyond the performance of traditional tabletop SEM’s and is capable of similar functionality of lower end full-size SEM systems.  Having more features than any other Tabletop SEM offers– the SNE-4500M Plus is simply the most advanced compact SEM in its price range.

Specimen positioning is achieved via movement of the fully motorized 5-axis stage (XYZRT) using the on-screen navigation window, stored coordinate recipes or a joystick. No other tabletop SEM in this class offers this capability.  A wide variety of sample holders are available to accommodate any type of sample.  The software offers the novice user a simple and clean interface free of clutter while the more advanced user can easily access features allowing further control of the microscope functions.

The software interface incorporates additional information for stage positioning, tilt assist and sample coordinate memory.

Secondary and Backscatter Electron image comparison

With the intuitive software, users are able to view and save either SE and BSE images or as a composite image combining both SE+BSE as shown below.  This composite image provides a great tool for investigative analysis by offering both topographical (SE) and composition (BSE) information in one single image.
