History

1951 Rigaku was founded by Dr. Yoshihiro Shimura. 1952 The core innovation of the company was the introduction of the world's first commercially available rotating anode

generator. 1954 Rigaku introduced the first automatic-recording X-ray diffractometer. 1976 Rigaku developed the first parallel-beam type X-ray diffractometer for stress analysis, as well as the first

spectrometers capable of
