Challenges of Modern Electron Microscopy
As research techniques continue to evolve, traditional TEM systems are finding it harder to keep pace with the demands of today’s labs. Scientists and engineers across a wide range of disciplines are, therefore seeking solutions that offer higher precision, greater ease of use, and the flexibility to adapt to shifting research needs.
Here are some of the major obstacles that researchers confront when working with traditional TEMs:
1. The Demand for High-Quality Imaging in Various Applications
Different research applications demand different imaging approaches, but many traditional TEM systems force a trade-off: high contrast for biological specimens or high resolution for materials science. Switching between these modes often requires multiple systems, driving up costs and adding complexity to already demanding workflows.
Beam sensitivity is another major challenge, especially when working with unstained or cryopreserved biological samples.
These specimens are particularly vulnerable to electron beam damage, making low-dose imaging techniques essential for preserving structural detail. However, not all TEM systems are equipped with the advanced digital imaging tools needed to balance sensitivity and resolution, limiting the quality and reliability of results when working with delicate materials.
2. The Complexity and Learning Curve in TEM Operation
Many TEM systems require substantial human control, which means that even simple activities like focusing, altering beam strength, and taking high-quality images can take time and require specialized expertise. This introduces a steep learning curve for new users and reduces research productivity.
To improve efficiency, modern research labs require automated systems that simplify routine procedures such as picture acquisition, sample navigation, and data processing. By lowering the number of manual modifications required, automation can help both new and expert users get consistent, high-quality results more quickly.
3. The Demand for Versatile, Multi-Functional TEMs
Today’s research is increasingly interdisciplinary, and that means labs need tools that go well beyond standard imaging. Techniques like scanning transmission electron microscopy (STEM) and energy dispersive X-ray spectroscopy (EDX) are essential for gaining deeper insight into sample composition and structure.
Without access to these capabilities in a single system, labs are often forced to either invest in multiple instruments or compromise on analytical depth, making research more costly, less efficient, and harder to scale.
4. The Need to Improve Ergonomics and Workflow Efficiency
Many classic TEMs require darkroom conditions, which might be uncomfortable during extended working sessions. The requirement for a specialized viewing chamber limits not only lab layouts but also the number of individuals who can access the equipment simultaneously.
Modern researchers want a more comfortable, well-lit working space that maintains imaging precision. A TEM that does not require a darkroom but still produces high-quality images can dramatically enhance user experience and workflow efficiency.

How the Hitachi HT7800 Solves These Challenges
The Hitachi HT7800 series is designed to meet the most pressing difficulties in modern electron microscopy by combining high-quality imaging, automation, versatility, and ergonomics in a single device.
Unlike classic TEMs, which need substantial manual operation or several instruments for varied imaging demands, the HT7800 simplifies processes and makes high-resolution imaging more accessible.
1. Optimized Imaging with a Dual-Mode Objective Lens
One of the most difficult aspects of TEM imaging is striking a balance between contrast and resolution for various sample types.
The HT7800 eliminates this trade-off with its Dual-Mode Objective Lens, which allows you to switch between High Contrast and High-Resolution modes depending on your sample requirements. By combining both modalities into a single system, the HT7800 saves time, money, and lab space while enhancing image versatility.
2. Simplified Operation and Automation
The HT7800 is also designed for ease of use, eliminating the complexity that is common with traditional TEM systems. It has automated functionalities that enable both expert and novice users to get high-quality outputs with little effort:
- Auto Multiple Frame (AMF) imaging automatically captures and stitches high-resolution images, eliminating the need for human alignment.
- Automated navigation and mapping identify and analyze regions of interest without ongoing changes.
- Drift correction and auto pre-irradiation improve image consistency by decreasing sample drift and optimizing beam exposure.
These characteristics serve to reduce training time, eliminate human error, and improve workflow efficiency, making the HT7800 a viable option for high-throughput research applications.
3. Multifunctional and Expandable for Advanced Research
Most research today is interdisciplinary; therefore, a TEM must provide more than simply imaging—it must also combine several analytical techniques.
The HT7800 was designed with expandability in mind, making it an excellent choice for biological, materials, and industrial research. It facilitates:
- The evolution of STEM hardware, allowing for comprehensive EDX analysis, mapping, and cost-effective hardware packages
- Classic scanning transmission microscopy using HHADF
- 3D electron tomography accurately captures three-dimensional structures for biological sciences and materials research
- MirrorCLEM technology enables correlative light and electron microscopy, closing the gap between fluorescence imaging and high-resolution electron microscopy. With these built-in and expandable features, the HT7800 responds to changing research requirements, allowing users to create processes and integrate numerous approaches in a single system.
4. Designed for Comfort and Productivity
Traditional TEMs frequently require darkroom conditions, which can be uncomfortable for long-term users. The HT7800 overcomes this restriction, allowing researchers to operate under typical room lighting settings using an integrated CMOS screen camera.
- Intuitive software and digital tools simplify operation for people of all skill levels
- High throughput and compact design optimize lab space for effective data capture
The HT7800 prioritizes ergonomics and usability, resulting in a more comfortable and productive research experience, making it an invaluable tool for both academic and industrial labs.
