kazato and kazuo ito met while working at the naval central institute in tokyo during world war ii . after the war kazato attracted ito and a group of others to mobara chiba prefecture japan . 10 11 this initial group developed a prototype magnetic field type electron microscope called the da 1 which was sold to mitsubishi in 1947 . 12 13 because of differences over the direction of this early company kazato and ito chose to found a new organization . 10 the japan electron optics laboratory company limited nihon denshi kogaku kenkyujo 13 was founded in 1949 by kenji kazato and kazuo ito in mitaka tokyo . 12 14 it produced its first commercial model transmission electron microscope the jem 1 12 a year later . overseas sales began in 1956 with the sale of a system to france . the company s strengths were the customization of orders to fit customer requests and the provision of strong customer support . 10 in 1961 the company was renamed jeol limited . its first overseas subsidiary

exchange by 1966 . 12 the company expanded from electron microscopy to nuclear magnetic resonance nmr releasing the first nmr system in japan the jnm 1 in 1956 . they produced their first mass spectrometer in 1963 and their first scanning electron microscope in 1966 . in 1968 they produced the first amino acid analyzer in the world the jlc 5ah . 12 the company also continued to develop its line of electron microscopes . the jem 7 in 1964 was the first electronic microscope to include a mechanism for the electrical adjustment of the lens axis . the jem 100b incorporated an electromagnetic deflection unit as well as an electromagnetic stigmator . the first photomicrograph of atomic arrangement in the world was taken by a jeol electron microscope in 1976 . 12 kazuo ito has expressed the company s philosophy as follows on the basis of creativity and research and development jeol positively challenges the world s highest technology thus forever contributing to the progress in both science and human society through its products . 10 in commemoration of jeol s 20th anniversary the kazato research foundation was created to support electron microscopy research . 15 kenji kazato retired as president of jeol in 1975 but continued to act as an adviser to the company until his death in 2012 . kazuo ito was jeol s president from 1982 to 1987 . the pittcon heritage award was posthumously awarded to them in 2016 for their contributions to scientific instrumentation . 12 16 operations edit jeol ltd. has four business segments . electron optics manufactures scanning electron microscopes transmission electron microscopes and scanning probe microscopes along with related equipment . the analytical instruments section s products include mass spectrometers nuclear magnetic resonance and electron spin resonance equipment . the industrial equipment segment covers a range of equipment particularly targeted at the semiconductor industry such as electron beam sources wafer process monitors and plasma gun series . finally the medical equipment segment manufactures automatic analysis devices clinical diagnostic systems and amino acid analyzers .
