HERMETIC WINDOWS

PA&E manufactures hermetically sealed windows for optical, laser and infrared applications producing windows that maintain the highest levels of hermetic integrity under the extreme environmental conditions space or defense-related LADAR, laser designation/acquisition systems and medical endoscopic tools must operate in.

Hermetic Packaging Wave Guide Window

Our hermetic windows offer engineers additional advantages beyond high hermetic performance, giving them the choise of a variety of optical glasses such as sapphire, quartz and BK10. These new windows are also designed to be laser welded to a range of metals, including aluminum, titanium and iron/nickel alloys, for additional flexibility.

PA&E offers a number of window sealing options including: proprietary active braze sealing; a patented direct sealing process; standard braze sealing and solder sealing.
