Engineers have sacrificed the rigidity, flatness, damping, and convenience of optical tops for baked, vacuum compatible machined structures of aluminum and stainless steel. Until now. TMC has combined our inherently clean CleanTop ® design with several new proprietary design features, cleaning methods, and a vacuum pump-down procedure developed for the University of Texas' Petawatt Laser Project to achieve a level of vacuum compatibility previously unattainable. Though this new design does not require baking (and is incompatible with baking), engineers at University of Texas' Petawatt Laser have achieved 8 x 10 -7 torr in a 7-foot diameter, 380 cubic foot chamber containing a 14-foot long CleanTop Optical Top. Closely correlated with their vacuum compatibility is the fact that these tops only out-gas extremely small amounts ensuring they do not damage optics (because attaining the target vacuum level would be of little value if the top emitted enough contamination to dam- age optics). The top for the Petawatt Laser application was demonstrated to cause less than a 0.1% loss in optical transmission of a test optic. We cannot guarantee precisely what level of vacuum you will achieve or what ratio of optical transmission you will maintain. But, we can guarantee that we will provide you with the same design features, cleaning methods, and recom- mended pumping procedures that assisted the University of Texas' Petawatt Laser in attaining a vacuum level of 8 x 10 -7 torr and less than 0.1% transmission loss. Optical Tops, Breadboards, & Supports (continued) Features • Patented CleanTop II clean optical top design • Stainless steel honeycomb core • Stainless steel CleanTop cups • Vacuum compatible core geometry • Vent fittings on table end-wall • Special cleaning of process materials • Cleaning and packing in accordance with strict standards of NIF Project (National Ignition Facility at Lawrence Livermore National Labs) • Special pump-down procedure used in conjunction • Developed in cooperation with the University of Texas Petawatt Laser Project (though not officially endorsed by U.T.) A 14-foot long TMC vacuum compatible CleanTop ® Optical Top mounted in a 7-foot diameter, 380 cubic foot vacuum chamber (shown with Siskiyou large, vacuum compatible, round-optics mounts). This chamber is part of the University of Texas Petawatt Laser. The table shown is TMC catalog number 730-455-02R. This is a 48 x 96 x 8 inch CleanTop ® Optical Top adapted for vacuum chamber installation. NEW From TMC!
