K.K. Gotō Kōgaku Kenkyūjo (㈱五藤光学研究所) is a Japanese optical company, which has made telescopes and astronomical optical devices since its foundation and currently (2007) still exists.
The company was founded in August 1926[1] by Gotō Seizō (五藤斎三), said to be a former employee of Nippon Kōgaku.[2] It sometimes used the Roman name Gotoh before the war.[3] It made the Triptar[4] lens mounted on the Miyako Six in 1942–3.
After the war, the company used the Roman name Goto Kogaku on some products, and it made the first Japanese planetarium projector in 1958.[5]
