Yamasaki Kōgaku Kenkyūsho (山崎光学研究所, meaning Yamasaki Optical Laboratory) is a Japanese lens maker.
See also the company Yamasaki Seiki Seisakusho which made the Bonny cameras in the first half of the 1940s and is probably unrelated.

K. Yamasaki (山崎光七),[1] founder of the company, was a former employee of Asanuma Shōkai.[2] He opened a camera shop called Shūzandō Yamasaki Shōten (秀山堂山崎商店) in 1924 and worked in the shop's basement after business hours to develop a camera lens.[3] The result of this hard work was the Congo 210/4.5 lens released in 1931.[4] Yamasaki has used the name "Congo" (コンゴー, Kongō) for its lenses since that date. The Japanese word kongō means "great strength" and "diamond", but it is said that the lenses were named after the Japanese battleship Kongō (金剛, usually spelled "Kongo" in English contexts), built in Britain as a battle cruiser in 1911 and sunk in 1944.[5] (The ship was itself named after the 1112m-high Mt Kongō (金剛山, Kongō-san) on the Ōsaka/Nara border.)[6]
The company was incorporated as K.K. Yamasaki Kōgaku Kenkyūsho (㈱山崎光学研究所, Yamasaki Optical Co., Ltd.) in 1955.[7] It is based in Hino-shi, suburban Tokyo (山崎光学研究所) since 1972.[8] It has concentrated on lenses for large-format cameras.
Yamasaki seems to buck stereotypes about Japanese companies. It caters for a niche market, advertises little, and sells directly via mail and its website; the FAQ in its website answers just three questions, of which the first is of why the prices are so low.[9]

- 180/4.5 (¥50)
- 210/4.5 (¥58)
- 300/4.5 (¥135)

A catalogue by Asanuma Shōkai dated October 1941 gives the following list of Congo lenses:[11]
- 150/4.5, tefuda format (¥71.90)
- 180/4.5, kabine format (¥84)
- 210/4.5, kabine format (¥101.10)
- 210/6.3, kabine format (¥41.65)
This source says that the f/4.5 lenses have four elements and the f/6.3 lens is a triplet.[12]
