Made-to-order production by skilled artisans! We accommodate a wide range of sizes, from small products at the millimeter level to large products.
The core technology of Yamamura Photonics, "sealing technology for glass and metal." This technology joins glass and metal, which are dissimilar materials, through an oxide film, achieving high airtight performance. We provide products for applications requiring high vacuum, such as vacuum circuit breakers for railways, medical X-ray tubes, endoscope components, and glass electrode tubes for ozonizers. We can accommodate various glass welding and bonding methods, including ring seals, disk seals, and terminal embedding, so please feel free to consult us. 【Features】 ■ High airtightness through oxide film formation ■ Custom production by skilled artisans ■ A wide range of sizes from airtight terminals to large vacuum containers ■ Stable appearance quality ■ Standard samples: All custom-designed *For more details, please refer to the PDF document or feel free to contact us.

Company information
Since its founding in 1949, we have developed our business based on the glass material technology and glass-to-metal sealing technology (GTMS) cultivated through glass products for vacuum tubes. Building on this accumulated technology, we have also aligned our innovations from vacuum tubes to semiconductors, and as a result of continuously providing various components that respond to the integration of light and electronics, our technology has now borne fruit in three business areas: "glass components for electrical and electronic devices," "optoelectronics packaging components," and "glass ceramics (LTCC)."
