The EM-30AX is one of the most advanced desktop SEM systems on the market today, offering high-end capabilities in a compact form factor. COXEM have developed the only desktop SEM configurable with either a Tungsten (EM-30AX Plus) or CeB6 (EM-30AX LE) electron source. Featuring high resolution imaging, with integrated dual SE and BSE detectors, the EM-30AX has powerful imaging capabilities. With the simple NanoStation operating software, and a 3-axis motorised stage as standard, ease of used is assured. The EM-30AX includes integrated AZtecOneGO EDS (Energy Dispersive Spectroscopy) from Oxford Instruments for elemental microanalysis. With the inclusion of EDS, COXEM's EM-30AX is a perfect platform for both electron microscopy and materials characterisation applications.

Ease of Use
The integrated features of the EM-30AX and COXEM's simple NanoStation operating software make ease of use guaranteed. Ideal for novice SEM users, NanoStation provides a simple and clean graphical interface, with quick access to common imaging settings. Users can click to move around the sample via a mini-map, which provides an overall view of the sample. NanoStation's Expert mode will satisfy the most demanding advanced users with access to a full range of settings and advanced features.
The EM30AX includes a motorised 3-axis XYT sample stage as standard, making it efficient and easy to control the position of the sample while in the chamber. An optional "NavCam" can capture an image of the sample holder when loaded, allowing users to navigate the samples visually.

Tungsten and CeB6 Electron Sources
COXEM's EM-30AX is the only desktop SEM platform available which can be configured with either a Tungsten (EM-30AX Plus) or CeB6 (EM-30AX LE) electron source. With a choice of electron source, a COXEM SEM has the flexibility to suit any application.
A tungsten filament electron source has a typical operating life of around 100 "beam on" hours, is low cost to replace, and be easily exchanged in less than 10 minutes. Tungsten filaments provide good imaging performance while remaining cost-effective.
CeB6, or Cerium hexaboride, filaments can produce a brighter image, which reduces noise and improves high resolution performance. The operating lifetime of a CeB6 filament is higher than a Tungsten, but has a much greater cost to replace. Replacing a CeB6 filament can require specialist maintenance, creating inconvenience and increasing downtime.
When finding the right SEM, deciding on the best electron beam source can be difficult. To help with this, the team at CN Tech are happy to provide guidance on finding the right SEM for any application.
Backscatter Electron Detector
COXEM's EM30AX desktop SEM features dual secondary electron (SE) and backscatter electron (BSE) detectors. The 4 quadrant BSE detector can be operated in Composition mode for atomic weight contrasted images, or Topo mode for producing topographic images of flat samples.
The BSE detector integrated into the EM-40AX is retractable without disconnection, being able to pivot away to a parking position. This unique feature can only be found in COXEM desktop SEMs. Retracting the BSE detector allows for a shorter working distance when using the SE detector.
3-Axis Sample Positioning Stage
A motorised 3-axis XYT sample position stage ins included as standard with COXEM's EM-30AX. Navigating a sample is easy with the NanoStation operating software, which features a "click to move" interface. To provide easier examination of a flat sample's topography, the stage can be tilted. Stage tilting is compucentric, adjusting the X axis to ensure the desired region of interest always remains the field of view while tilting.
Using the 3-axis motorised stage and NanoStation operating software together provides a Panorama mode, for capturing high resolution images of large samples. Hundreds of thousands of images can be collected across a large sample, through automatic control of the motorised stage. COXEM's NanoStation software can then automatically stitch the images together, creating a single high magnification image of a large sample.
Energy Dispersive Spectroscopy (EDS) capability is fully integrated into COXEM's EM-30AX Desktop SEM. With integrated EDS Analysis, elemental and chemical analysis of samples can be performed on materials at high magnifications.
COXEM have partnered with Oxford Instruments, a leading developer of materials characterisation tools for in-situ use in electron microscopes. Oxford Instruments have produced a miniaturised form of their AZtecOne EDS technology for a desktop electron microscope, called the AZtecOneGO.
The Oxford Instruments AZtecOneGO EDS system included in the EM-30 AX consists of the intuitive AZtecOneGO software, and Oxford Instrument's reliable and accurate compact x-act Silicon Drift Detector (SDD). AZtecOneGO is the ideal solution for conducting EDS analysis as quickly and easily as possible.
With a simple, streamlined interface, AZtecOneGO is quick and easy to use, even by novice users with no advanced knowledge of the EDS technique. Features include X-ray mapping and linescanning, spectrum acquisition, and fast report generation.
