During the difficult period after the war, Shimadzu helped support the post-war recovery by producing products such as coal mining machinery required for increasing production in the key coal industry, X-ray systems for medical facilities throughout Japan, and spinning pumps and nozzles used in the fiber industry, which was an important export industry. Meanwhile, Shimadzu created many new "Japan's first" and "world's first" products more typically associated with Shimadzu, such as electron microscopes, gas chromatographs, photoelectric spectrophotometers, directly-read optical emission spectrometers, and remote-controlled X-ray fluoroscopy systems.
