About FCC
Representative Message
Fine Crystal Co., Ltd. (FCC) was established on August 22, 1988 as a subsidiary of Japan Steel Works, Ltd.
Because Japan Steel Works, Ltd. held a 100% share of the domestic market for pressure vessels (autoclaves) used to manufacture quartz crystals, FCC was established to use these pressure vessels to grow and sell synthetic quartz crystals.
From there, we have developed not only growth technologies but also processing technologies to provide a range of products, including optical low-pass filters, crystal wafers, and waveplates.
We also process a variety of materials for other organizations using our processing facilities.
In this way, FCC is committed to helping your business grow by providing products and services that meet your needs.
FCC is also committed to providing products that satisfy our customers by constantly exploring the latest technologies and offering the highest quality products.
FCC will continue to solve social issues and make the world more sustainable and prosperous with the power of the Japan Steel Works Group's Material Revolution🄬.
We sincerely appreciate your support and patronage.
