By: PA&E PA&E’s ceramic-sealed hermetic windows offer engineers additional advantages beyond high hermetic performance. Because Kryoflex seals at relatively low temperatures, they can now choose from 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. Windows produced with this new process are extremely robust and reliable because a key point of failure – solder joint fatigue – is eliminated. They provide a leak rate equal to or less than 1X10-9 cc/sec helium at 1 atmospheric differential pressure, even when subjected to extreme thermal and mechanical shock and, in medical applications, will maintain integrity after repeated autoclave sterilization. Unlike solder- or braze-sealed windows, PA&E’s ceramic-sealed hermetic windows do not require metallization. Eliminating this step can, reduce both costs and processing time and allows anti-reflective coatings to be applied after the sealing process, ensuring that the critical A/R coating is not impacted by subsequent processing. PA&E also offers a number of other window sealing options including: proprietary active braze sealing; a patented direct sealing process; standard braze sealing and solder sealing.
