History

Nittō Kōgaku K.K. (日東光学株式会社) is a Japanese optical company. It was founded in 1876 as a silk producer. In 1943 the company was restructured as an optical manufacturing company and renamed to Nittō Kōgaku (日東光学機械製作所), usually rendered in English as Nittoh Kogaku. In the 1940s, the company worked with Nihon Kogaku (now known as Nikon). In 1951 the company incorporated as a joint stock company and became known as Nittoh Kogaku K.K.. In 1996, the company launched an Indonesian production facility as a joint venture with Mitsui & Co., Ltd. and Astra Group, known as Pt. Adiwira Presisi Industri. In 2007 the company acquired Shoujoh Seiki Co., Ltd. and reorganized it into a subsidiary to boost production capabilities. In 2008, the company acquired full shares of the Indonesian factory, making it a wholly owned subsidiary.[1]

In 1950, it started to manufacture "Kominar" (コミナー) lenses used in a variety of cameras, as well as enlarging lenses. In 1961 the company began to manufacture complete cameras.[1]

The company's address in 1960 was Chiyoda-ku Kanda Asahichō 18–2 (千代田区神田旭町18–2) in Tokyo.[2]

Nittoh Kogaku also made cameras as a subcontractor for other companies, beginning with the Fujipet in 1960. Examples included the Olympus Trip 35, the Revue 400 EF and so on.

Today the company continues to manufactures optical equipment including plastic lenses, CCTV lenses, projection lenses, lens modules for digital still cameras.[1]
