Transmission electron microscopy, also known as TEM, is a type of microscopy in which an electron beam is passed through a specimen to produce an image.
Most of the time, the specimen is a suspension on a grid or an ultrathin section less than 100 nm thick. As the beam travels through the specimen, the electrons interact with the sample to create an image.
After that, the image is enlarged and focused on an imaging device like a fluorescent screen, a layer of photographic film, or a charge-coupled device-attached scintillator sensor.
Because electrons have a shorter de Broglie wavelength, transmission electron microscopes can image at a much higher resolution than light microscopes.
A single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope, can be captured in this way by the instrument.
In the physical, chemical, and biological sciences, transmission electron microscopy is an important analytical technique. TEMs are utilized not only in studies of pollution, nanotechnology, semiconductors, and cancer, but also in studies of virology, materials science, paleontology, and palynology.
Conventional imaging, scanning TEM imaging (STEM), diffraction, spectroscopy, and combinations of these are all possible modes of operation for TEM instruments. “Image contrast mechanisms” refer to the many fundamentally distinct means by which contrast is produced even in conventional imaging.
Position-to-position variations in thickness or density (mass-thickness contrast), atomic number (Z contrast), crystal structure or orientation (crystallographic contrast or diffraction contrast), the slight quantum-mechanical phase shifts that individual atoms produce in electrons that pass through them (phase contrast), the energy lost by electrons on passing through the sample (spectrum imaging), and more can all contribute to contrast.
Every system tells the client an alternate sort of data, depending on the difference instrument as well as on how the magnifying instrument is utilized — the settings of focal points, gaps, and indicators.
This indicates that a TEM is capable of returning a remarkable variety of information with atomic and nanometer resolution, ideally revealing not only the location of all atoms but also their types and bonds. Because of this, TEM is regarded as an essential tool for nanoscience in the fields of biology and materials.
The Global Transmission Electron Microscope market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The HT7800 Series, a new Transmission Electron Microscope (TEM) model, was announced by Hitachi High-Tech (8036). The HT7700 model’s digital operation under normal room light conditions is carried over to the product, which also includes improved electro-optics and numerous new features.
TEM’s ability to observe nanostructures is utilized in numerous fields, such as medical diagnosis and research, bioscience, pathology, food product development, polymer development, chemistry, and nanomaterials.
As of late, with the scaling down of materials for perception, utilizing TEM to perform underlying examination has become ordinary in a rising number of circumstances.
This has resulted in an increase in the number of users, which calls for both enhanced operating environments that do not necessitate a high level of expertise or knowledge to be utilized effectively and performance enhancements such as high-resolution and high-contrast imaging.
The current HT7700 model, when it was first introduced, revolutionized traditional observation methods by removing the antiquated traditional viewing chamber and integrating a digital camera system. The newly launched HT7800 Series has inherited many advantages from that model.
The HT7800 once more exemplifies the application of cutting-edge technology, resulting in a system that is more precise, ergonomic, and simple to operate in normal room lighting.
High-performance imaging with low magnification, high contrast, a wide field of view, and high resolution is made possible by this new model’s unique Hitachi Dual-Mode Objective Lens and advanced electro-optics*2. In particular, the HT7830 model has a unique ultra-resolution lens configuration that enables it to deliver high-resolution performance that is unparalleled in its class.
The system’s user interface has a novel feature that enables visualization and navigation of entire grids, making it easy to use and efficient. An overview image can be used to automatically capture images at user-defined locations, which is made possible by the newly developed Image Navigation function.
Hitachi High-Tech will continue to promote development and sales expansion while making significant contributions to technological advancement as part of its mid-term management strategy to become the global leader in electron microscopes.
In addition, the Hitachi High-Tech Group will continue to work toward its goal of “becoming the Global Top in high-tech solutions” and will respond quickly to customer and market needs by considering the customer as a fast-moving creator of cutting-edge businesses.
