EM-30 Plus & LE Benchtop Scanning Electron Microscope
High accuracy, high speed nano indentation in-situ in vacuum environments. Perform nanomechanical testing inside a SEM chamber, and synchronise SEM imaging with mechanical property data. Custom experiments can be easily configured. The suite of options available, such as the InForce50 electromagnetic actuator, combine to deliver quantitative results that lead to valuable solutions in material research.
COXEM manufactures and provides Scanning Electron Microscope (SEM), the most widely used platform technology in Nano- Metrology of Nano-scale. As a partner of Nano-fusion technology that changes industrial condition in 21 century, COXEM tries to provide the best quality service. SEM is the precision instrument, can be used for analyzing the shapes or constituents of microstructure materials in quantitative and qualitative. SEM is an essential instrument for development of basic science and an indispensable infra for technical innovation, used in chemistry, biology, material science as well as nano-materials and nano-biology.

Ease of Use
Ease of use is guaranteed with the integrated features of the EM-30, and COXEM's simple NanoStation operating software. 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. Users with advanced knowledge of electron microscopy can access the full range of settings and advanced features with NanoStation's Expert mode.
The EM-30 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. Users can navigate the samples visually with the optional "NavCam", which capture an image of the sample holder when loaded into the chamber.

Tungsten and CeB6 Electron Sources
The EM-30 is the only benchtop SEM platform on the market today that can be configured with either a Tungsten (EM-30 Plus) or CeB6 (EM-30 LE) electron source. Because of this, COXEM's benchtop electron microscope systems have unrivalled flexibility.
Tungsten filaments have an operating life time of approximately 100 "beam on" hours, have a very low replacement cost, and are easily exchanged by a user in 10 minutes or less. Using a Tungsten filament electron source can be more cost effective.
A CeB6 (Cerium hexaboride) filament can produce a brighter image, reducing noise and improving high resolution performance. However, while the operating lifetime of a CeB6 filament is higher than Tungsten, the replacement cost is much greater. A CeB6 filament can also require more specialised maintenance to replace. When finding the right SEM, choosing the correct 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 EM30 benchtop 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 benchtop 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-30. The a "click to move" interface of the NanoStation operating software, makes navigating around a sample quick and easy. 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.
Combining the NanoStation operating software with a standard 3-axis motorised stage, has allowed COXEM to develop a Panorama mode. Panorama mode provides high resolution image capture for large samples. Hundreds of thousands of images can be collected across a large sample, through automatic control of the motorised stage. These images are then automatically stitched together by NanoStation, creating a single high magnification image of a large sample.
