The LVEM5 provides unmatched versatility by integrating 4 imaging modes into one very capable yet benchtop sized microscope. Depending on system configuration the LVEM5 can alternate between operating as a Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM), Scanning Transmission Electron Microscope (STEM) and can even provide Electron Diffraction (ED) data without ever having to re-align the column or adjust the sample. This allows both surface and transmission images of the sample to be captured from the same area of interest. The ability of a single instrument to undertake multiple imaging modes can’t be understated, and it is quickly becoming the indispensable tool of choice for many research labs.

Key Technical Features
The miniature architecture of the LVEM5 allows the system to be installed practically anywhere, whether it be a benchtop, classroom or mobile lab. In every case the system takes up minimal room and resources.
This hardware-based enhancement of the basic TEM imaging mode provides increased total magnification and higher resolving power in the TEM images. A more advanced and powerful projective lens, combined with a far more sensitive camera allows for higher image quality as well as higher magnification and resolution.
Turbomolecular Pump with Diaphragm Pump
This airlock system pump guarantees a quick and clean sample exchange.
2 Ion Getter Pumps
These pumps ensure a non-contaminated sample space to always provide stable imaging conditions.
5kv Field Emission Gun
The Field Emission Gun (FEG) is a low voltage Schottky type with very high brightness and spatial coherency. This allows for strong interactions between electrons and the sample. The minimum expected lifetime of the FEG is around 2,000 hours.
A high-resolution final TEM image is projected onto the YAG Screen via the electron beam. From there, light optics take over to produce an image onto the computer screen.
The fully motorized manipulator allows a sample to be easily and precisely repositioned inside the column, allowing for imaging of the entire sample.
Imaging is a breeze with the intuitive and comfortable controls that allow easy adjustment of illumination, magnification stage movement and beam correctors.

SEM mode – Backscatter Electron Detector (BSE)
For SEM image acquisition, the LVEM5 employs a Backscatter Electron (BSE) detector which is broken into quadrants, offering a stereoscopic view of the object. Material and Relief modes are also possible, giving a detailed understanding of the surface texture. The BSE detector is sensitive to density of the sample, giving contrast based on atomic number, this can be useful in differentiating materials from one another.
STEM – Photomultiplier
With the addition of the STEM photomultiplier, the versatile LVEM5 has the added capability of scanning transmission microscopy, which can be useful in situations where samples are stained or simply too thick to act as a conventional TEM sample
The LVEM5 is controlled through our intuitive user interface. It allows for monitoring and adjustments to all important microscope parameters. Through the software it is possible to switch seamlessly between all imaging modes. The software can also serve as a virtual keyboard, replicating most of the function of the LVEM5 operating console. Image acquisition in all modes is also carried out directly within the LVEM5 software, providing the capability for live FFT, scale bar display and measurements to be made on the live image. There is also full software control over the image detectors to make adjustments to image brightness and contrast as well as a live-histogram auto-correction and bit-depth selection in the TEM mode.
For image post-processing tasks, the LVEM5 software kit includes QCapture Pro software allowing for contrast adjustments, multiple on-image measurements with export function, spatial filtering and other useful manipulations. In any case, the images are saved in non-proprietary formats, which can be imported into your favorite image analysis software, such as ImageJ.
