Katsuma Kōgaku (勝間光学, translated as Katsuma Optical Co.) is a Japanese company. It is mentioned by various sources as a binocular maker. In 1932, it was one of the two founders of the company Tōkyō Kōgaku (later Topcon), together with the measure instruments branch of Hattori Tokei-ten Seikōsha (服部時計店精工社).
After the war[1], it made cameras with the Lyra brand name and used the Terionar brand name for some lenses. These brand names were used until 1944 by Fuji Kōgaku. The company also used a KATUMA[2] LYRA logo that was similar in shape to the logo used by Fuji Kōgaku. This page at Japan Family Camera says that the latter company was split in two parts after the war: Taisei Kōki and Katsuma Kōgaku, with the latter one keeping the Lyra brand name. It seems more probable that Katsuma Kōgaku bought the brand names to what remained of Fuji Kōgaku after the war, while the company itself was reformed as Taisei Kōki.
