Delong Instruments is a pioneering company dedicated to advancing electron microscopy through innovation, accessibility, and precision. Founded in Brno, Czech Republic, a global hub for electron optics. Our mission is to democratize high-performance electron microscopy, making it practical and affordable for universities, research centers, and industry laboratories worldwide. For over three decades, Delong Instruments has specialized in compact, reliable electron microscopes that push the boundaries of what is possible at low accelerating voltages.

At the heart of our portfolio is the LVEM 5, the world’s first and only benchtop transmission electron microscope. Designed for powerful imaging in a remarkably small footprint, the LVEM 5 brings electron microscopy into laboratories that might otherwise lack the space, infrastructure, or budget for a conventional high-voltage instrument. Operating at low voltages, it enables fast, routine nanomaterials characterization and versatile imaging across TEM, SEM, STEM, and ED modes.

Building on this success, the LVEM 25E delivers the next generation of low voltage TEM. Combining the high resolution of field emission technology with the advantages of low voltage imaging, it produces nanometer-scale detail while preserving contrast in delicate or unstained samples. With optional EDS for chemical analysis, the LVEM 25E offers advanced performance while remaining easy to install, operate, and maintain. Applications range from clinical pathology and pharmaceutical R&D to advanced materials characterization.

What sets Delong apart is our philosophy: high-quality imaging should be within reach of every laboratory. Our microscopes require minimal infrastructure and are practical for a wide variety of environments. By lowering barriers to access, we empower researchers, educators, and innovators to explore the nanoscale with confidence.

Delong Instruments is your way to electron microscopy.
