From Sanko
We are a manufacturer of measuring instruments with a history of 80 years.
We manufacture golf instruments, golf tool-related products, glass condensing mirrors,
and large precision reflectors.
A large vacuum vapor deposition system is installed at the Ina branch.
We can also handle only vapor deposition work according to the customer's request.

We are currently developing a large reflector that is lighter than conventional glass mirrors.
Some technologies are used in mirrors for CTA.
