Standard Hermetic Optical Window, Weldable

Tekna Seal's hermetic optical windows are designed to facilitate visual observation or optical signal transmission into hermetically sealed devices. The body of the window assembly is stainless steel and is intended to be laser welded into a device housing, vacuum chamber or vacuum flange. The window glass is fused directly to the metal body using the Tekna Seal oxide-free glass sealing process for the lowest possible leak rate.
