ophthalmologyand surveying. Their headquarters are in Itabashi, Tokyo. They are affiliated with Toshiba, which holds 40% of Topcon's stock.
Prior to the end of
World War II, Topcon sold optical equipment to the Imperial Japanese Army.
*1932 The surveying instrument division of Hattori Watch Company Seiko-sha became the basis for the new company, at first known as "Tokyo Kogaku Kikai Kabushiki-gaisha." Their headquarters were in the Ginza area of what was then known as
Tokyo City(presently Chūō).
*1947 The company listed its shares on the Tokyo and Osaka Stock Exchanges.
*1960 They affiliated themselves with Tokyo Shibaura (now called Toshiba).
*1989 Tokyo Kogaku changed its name to Topcon.
Tokyo Kogaku produced
cameras, beginning with a 6×4.5 cm medium format model in 1937. A 127 filmcamera followed the next year. After the war, the Primoflex I twin-lens reflex cameracame out in 1951. The Topcon 35A was born in 1953. In 1960, the company produced a 6x9 press cameraon order from the Tokyo Metropolitan Police Department. It initially used a Mamiyalens; civilian models became available with Topcon lenses.
With the 35 mm Topcon RE Super of 1963, the company pioneered full-aperture metering. Tokyo Kogaku continued to innovate until leaving that line of business in 1981.
About 1965 the US Navy tested cameras from several Japanese and German manufacturers (including Nikon's F). The Topcon Super D was the winner of this competition and served in the Navy until the very end of Topcon production in 1977.

Brisbaneoffice. These operations deal mostly with Agricultural Guidance Systems by means of GPSand producing Topcon's own surveying equipment data processing software.Officially dedicated in August 2006, this office is quickly growing into a major player in the development of Ag. Guidance Systems and Surveying equipment. Employing talented computer engineers, Topcon delivers GPS systems that have been well researched, tested and developed. Suffice to say Topcon is in the running for market leader in the field of agricultural guidance systems, a concept still relatively young. Topcon is fast making this method of guidance system a global success.*
