Glass To Metal Seals
Description
Describing glass-to-metal seals is the easy part. Producing a good one requires knowledge and experience. With decades of experience, our skilled artisans perform specialized operations such as sealing faceplates or metal rings to a variety of fabricated vacuum tubes. Working with a variety of materials, including several types of glass, kovar, and ceramics, we produce components that are used in lasers, infrared systems, semi-conductors, and photomultipliers.
Our production staff includes glassblowers with an array of glassblowing skills. Forming, shaping, blowing, bending, molding, and sealing are included in their repertoire. These processes can be performed in several glass types. Glass to metal seals with kovar, tungsten, and platinum are also common. Our hydrogen firing process of kovar assures the quality of the seal. Seals can be hermetic or compression by design. Graded seals, with glasses of different expansion, can also be sealed together under certain criteria. Window seals are commonly made with dissimilar materials without distortion. Anodes, cathodes, and getters can be installed as required.
