History of Yamagata Factory


Yamagata Factory started in 1982 to manufacture magnetic head for VCRs.
After that, we started to produce lens-barrel units in 1985. Production of inner focus type was started in 1992, and production of lens-barrel unit for DSC was started in 2002.
As for lens, spherical grinded lens production started in 1984, and aspherical lens production started in 1989.

SD Card production started from 8MB card in May 2000. Now, we produce 7 kinds of memory capacity up to 512MB.

Optical lens booth

Optical lenses are produced on the 1st floor of No.1 factory. Generally, the construction process includes grinding, pressing, cleaning, inspection, etc. every process requires specialized techniques/technical skills/managerial ability.

Prism evaporation used for 3CCD Camcorders is also produced on this floor.

SD Card booth

SD Card is produced on the 2nd floor of No.1 factory.

This evaluation facility can accurately measure the shape of aspheric lens with no-contact atomic force method.

Accuracy level is from 0.01 to 0.05 ? and widely utilized to control the quality of mold sand products.

Comparing with other makers, we can produce better quality aspheric lens by using the UA3P.
