KYKY.Founded in 1958, KYKY was the first public institution under the Chinese Academy of Sciences to undergo comprehensive restructuring into an enterprise. Over more than six decades of development, it has remained dedicated to the fields of electron optics and vacuum technology, undertaking numerous critical national scientific research projects. The company developed China's first scanning electron microscope, first turbo molecular pump, and first commercial helium mass spectrometer leak detector. Its new product R&D achievements consistently represent the pinnacle of China's high-end electron optical instruments and vacuum technology. In recent years, it has successfully developed China's first field emission gun scanning electron microscope and first magnetic levitation molecular pump, both reaching world-class standards. The company's business spans scientific instruments such as scanning electron microscopes and helium mass spectrometer leak detectors, as well as core components and industrial equipment including molecular pumps and vacuum application devices. Its products are widely applied in cutting-edge scientific research and high-end equipment manufacturing across aerospace, semiconductors, automotive, new energy, new materials, and energy conservation/environmental protection sectors. Key products include: Scientific instruments and equipment; SEMs and ancillary equipment, including SEMs, energy dispersive spectrometers, compact sputtering systems, compact coating machines, accessories/consumables, and helium mass spectrometer leak detection equipment; Helium mass spectrometer leak detectors, fluorinated oil platforms, gas-recovery helium mass spectrometer leak detection systems, pumps and vacuum equipment, vacuum acquisition products; molecular pumps, rotary vane pumps, pump units, vacuum application equipment; leak detection engineering and equipment, space environment simulation systems, vacuum process equipment, ultra-high vacuum exhaust systems, vacuum support products; vacuum gauges, vacuum valves.
