Apertures
SEM apertures enable users to create high-quality imaging of a variety of sample types by refining and customizing the properties of an SEM’s electron beam. Similar in purpose to an optical microscope aperture, the apertures utilized in SEM are engineered to provide users with the control to create optimal conditions for SEM imaging.
SEMs employ apertures at several different stages of the imaging process, and at EMS, we carry a broad selection of SEM apertures to accommodate your needs. From Wehnelt apertures used to control the emission of electrons directly from the cathode to disc apertures that help control the angular range of signals and influence critical image elements like resolution and contrast, choosing the right SEM aperture can make or break the quality of your image. Since maintaining the integrity of your aperture is paramount, we also carry several products designed to facilitate aperture upkeep and cleaning, including aperture flamers.
