Product Announcement from SOURIAU PA&E
SOURIAU 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.
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 after repeated (1,000+) autoclave sterilization cycles. SOURIAU PA&E's ceramic-sealed windows have also passed cytotoxicity testing so all window materials are proven safe for use within the human body.
Unlike solder- or braze-sealed windows, SOURIAU PA&E's ceramic-sealed hermetic windows do not require metallization. Eliminating this step can, reduce 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.
