Achieving high airtightness and high reliability! Capable of supplying products with stable quality from small to large-scale production.
The "Melted Lens Cap" is a component that directly bonds a glass lens to a metal can through welding. It was developed as a cost-reduction product for ball lens caps, as it does not use precision-ground lenses and does not bond with low-melting-point sealing glass (i.e., it has fewer components). Compared to flat window caps, it has light-gathering capabilities, making it particularly well-suited for use in packages for light-receiving elements. 【Features】 ■ High airtightness and high reliability ■ Contributes to miniaturization ■ Custom design support ■ Abundant mass production track record *For more details, please refer to the PDF materials 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)."
