小貫光学工業所 Company Profile

We offer high durability and high strength titanium nitride coating.

Kounuki Optical Industry Co., Ltd. started lens processing in 1964 and was established in April 1966. In 2013, we applied the coating technology developed through lens processing to establish a factory specializing in metal films. We aim to be of even greater service to our valued clients in various fields, as well as to assist those in industries different from lens products.
