Optical Component: Melted Lens Cap

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.
