# JEOL

> JEOL Ltd. is a Japanese scientific instrument manufacturer founded in 1949 in Tokyo, Japan, that produces electron microscopes, NMR spectrometers, mass spectrometers, and other analytical instruments used in materials science, life science, semiconductor research, and chemistry. JEOL's transmission electron microscopes (TEMs) and scanning electron microscopes (SEMs) are among the highest-resolution instruments available, with their JEM-ARM family of aberration-corrected scanning transmission electron microscopes achieving sub-Angstrom imaging capabilities essential for atomic-resolution materials characterization in materials science, solid-state physics, and nanotechnology. Their cryo-TEM instruments, including the CRYO ARM series, are state-of-the-art platforms for cryo-electron microscopy of biological macromolecules, widely used for structural determination of proteins, viruses, and membrane complexes. JEOL's NMR spectrometers, competing with Bruker in high-field instruments, are valued for their magnet stability and sensitivity in organic chemistry, structural biology, and metabolomics research. The company's Fourier transform mass spectrometers based on Orbitrap and high-resolution time-of-flight technologies provide exact mass measurements for metabolomics, proteomics, and natural products characterization. JEOL scanning electron microscopes with focused ion beam capability (FIB-SEM) enable three-dimensional tomographic reconstruction and site-specific TEM sample preparation from bulk materials. Their electron beam lithography systems are used in the fabrication of nanostructure research prototypes and advanced photomask manufacturing.
