High reflectivity, high durability metal reflector "Metal Mirror"
High-performance metal mirrors with functional coatings on the surface (high-reflective coatings, protective coatings). They can be used as components requiring high reflectivity or as durable mirrors. The surface is extremely smooth, with surface roughness at the nano level. The shapes are not limited to flat surfaces; curved surfaces such as spherical, concave, and convex shapes are also possible. ◆ High-reflective coating The surface achieves a higher reflectivity than that of polished metal mirrors. (Reflectivity close to 100% is also achievable.) ◆ Protective coating With a protective coating, the mirrors can withstand harsh environments. Additionally, they become less susceptible to scratches and dirt. They can be used in products that require high durability. ◇◇ For more details, please download the catalog or contact us ◇◇

basic information
We perform dielectric film treatment on the surface of metals to enhance functionality. The dielectric film is optically transparent, very thin, and has minimal impact on the shape. The surface accuracy after film treatment is on the order of several wavelengths (several micrometers). ◇◇ For more details, please download the catalog or contact us ◇◇

Company information
Our company has been engaged in surface treatment technology for over 60 years, incorporating the philosophies of ISO 14001 and ISO 9001 into our processes, ranging from metal houseware products to semiconductor manufacturing equipment components. Through thorough quality control and technological development, we provide surface treatment processes that meet the demands of the times. Our electrolytic composite polishing has received high praise, including a letter of appreciation for contributing to the completion of the Japan Proton Accelerator Research Complex (J-PARC), a high-intensity proton accelerator facility constructed jointly by the Japan Atomic Energy Agency (JAEA) and the High Energy Accelerator Research Organization (KEK). We perform various surface treatments that maximize the advantages of different metal materials, including electrolytic polishing, electrolytic composite polishing, coloration of stainless steel and titanium, and pickling. In recent years, we have also been involved in surface treatment processing for materials such as magnesium, aluminum, and titanium. Leveraging the expertise in surface treatment developed in the Niigata Prefecture Tsubame-Sanjo region, which is well-known for metal processing, we are here to assist you in solving your problems.
