Simlar
Simlar (シムラー) lenses were made by Tōkyō Kōgaku from 1937 to 1955. The name Simlar (written shimurā in Japanese) is derived from Shimura (志村), a place name in Tokyo where the company plant was located.[1] The Simlar brand was originally used for a four-element lens design, copy of the Tessar. From the late 1930s or early 1940s, the name was applied to all the lenses made by Tōkyō Kōgaku with advanced specifications, as opposed to the Toko or State brands, used for three-element lenses. In 1955, the names Toko and Simlar were replaced by the single brand Topcor.
