American and Japanese companies controlled the market for advanced microscopes. Now, China is offering an alternative. China has officially launched the mass-market production of its own high-performance 200-kilovolt transmission electron microscope.
Reports suggest that Hefei-based manufacturer CIQTEK unveiled the microscope at the 2026 National Conference on Electron Microscopy in Nanjing. The TEM-F200 delivers advanced imaging capabilities with a point resolution of 0.25 nanometers. It also has a 0.1-nanometer resolution limit, allowing researchers to capture structural details at the atomic level.
Scientists and engineers use electron microscopes to analyze molecular structures, study biological viruses, and inspect microscopic defects in semiconductor microchips.
Atomic-scale precision
It is a microscopic leap with massive geopolitical consequences.
For a long time, global research labs and semiconductor foundries depended almost entirely on a tiny cartel of American and Japanese instrument giants. China bought them by the thousands. Without them, domestic chipmakers couldn’t inspect microscopic circuit defects, and biopharma firms couldn’t map molecular structures.
The TEM-F200 could eventually help China take charge. An electron microscope is an advanced imaging tool that uses a focused beam of electrons, rather than light, to illuminate and magnify extremely small specimens.
At an accelerating voltage of 200kV, the microscope delivers optimal performance, capturing ultra-fine atomic detail while preserving sensitive specimens.
According to the South China Morning Post, CIQTEK Chairman He Yu confirmed that the microscope has moved beyond R&D into full factory “mass production and delivery”. The new device is already capable of supporting defect analysis for next-generation semiconductors and advanced materials.
The timing is important. Beijing has deliberately accelerated efforts to address supply-chain issues in advanced scientific tools and semiconductor manufacturing.
Advanced electron microscopes depend on volatile raw materials, including rare earth elements, tungsten, platinum, and specialized semiconductor components.
Plus, these atomic-resolution devices are also classified as dual-use technologies with major military and industrial applications, making them frequent targets of international trade sanctions and export restrictions. With a small group of nations, including the U.S., Japan, Germany, and the Netherlands, dominating these supply chains, domestic production has become important for national security and technical independence.
China’s rapid progress
China achieved self-reliance in microscopy in a remarkably short timeframe. The nation debuted its first commercial 120kV field-emission TEM in 2024, and Bozhon Instrument Technology unveiled the first 200kV prototype in 2025.
Technical progress expanded in May 2026 when the Chinese Academy of Sciences introduced the AI-driven Aeye-1 system. Domestic capabilities reached full commercial scale in October 2026 with the mass production of both the TEM-F200 and the TEM-F120 models.
Overall, the field has a long and interesting history worth mentioning. The development of light microscopes in the 17th century first expanded human vision beyond its natural limits. Of course, the technology was limited then, with a resolution of about 200 to 250 nanometers.
This barrier prevented from viewing viruses and genetic structures until German researchers built the first working electron microscopes in the early 1930s. Rather than using light, electron microscopes direct focused beams of electrons at or through samples to capture atomic-level images on digital displays.
Wu Aihua, secretary-general of the analytical instruments branch at the China Instrument and Control Society, said this development could boost national self-sufficiency in analytical testing.
