Custom support starting from small lots! We support customer development for applications that require more precise optical design.
At Yamamura Photonics, we offer aspheric lens caps and holders that are bonded to metal cans using low-melting-point sealing glass. Furthermore, since 2018, Taiwan Yamamura Optical has joined the Yamamura Group, enabling us to provide newly integrated molded aspheric lens products. The aspheric lens caps and holders from Taiwan Yamamura Optical are products that directly bond the lens to the metal can using precision molding methods. We offer both coupling and collimating types, and all varieties are produced in-house at our factory. We support customer development for applications requiring more stringent optical design, such as optical communication, display applications, and detector applications. 【Features】 ■ A wide range of standard products ■ Quality assurance system for domestic sales in Japan ■ Customization available ■ High reliability and high airtightness *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)."
