Request InfoXEI Scientific Inc.REDWOOD CITY, Calif., April 13, 2011 — XEI Scientific Inc., manufacturer of the Evactron plasma cleaning system for electron microscopes and other vacuum chambers, has announced that the product can be used to clean carbon decontamination using hydrogen. According to the company, atomic hydrogen created by the Evactron plasma is effective in cleaning carbon contamination from extreme-ultraviolet (EUV) optics. All Evactron decontaminator systems use radio-frequency plasma to produce oxygen radicals that flow downstream through the chamber, removing contamination. They also are safe for use on x-ray windows and are delivered...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueZinc Selenide OpticsHigh-quality zinc selenide (ZnSe) lenses, output couplers, and mirrors from Laser Research Optics are optimized at 1.06 μm for medical laser OEMs. The devices are manufactured to...Photonics Showcase April 2022 IssueMicroscope CameraThe LC35 microscope camera from Olympus Corp. provides quality brightfield images in a cost-effective package.
