The "Ball Lens Cap" is a component that joins a ball lens, which has been polished with high precision, to a metal can using low-melting-point sealing glass. It is mainly used for light collection and coupling applications, and due to its cost-effectiveness, it has been adopted by many customers both domestically and internationally, particularly in the access systems of optical communications. Yamamura Photonics offers standard-sized caps for TO-CANs, as well as accommodating some design modifications such as height and lens changes, completely new designs for special shapes, and custom designs for optical coatings. 【Features】 ■ High airtightness and high reliability ■ Lineup of standard sizes for TO-CANs ■ Custom design support for size and optical coatings ■ Extensive mass production track record *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)."
