In the mid-1950's a group of scientists in the Institute of Optics, what is now Tsukuba University, required an infrared spectrophotometer for research. Since a commercial instrument was not available, they undertook the challenge of developing their own. The result was quite a success: a reliable instrument with exceptional optical performance.
Soon thereafter, other researchers began requesting replicas of the instrument. In response to this increasing demand, the Japan Spectroscopic Corporation (JASCO) was founded in 1958 in order to provide the scientific community with optical spectroscopy products. Founding members include world-famous physicist Yoshio Fujioka and Nobel Prize winner Shinichiro Tomonaga.
