Multi-CF Thin Flanges are typically used as 1) spacers to gain separation between components, 2) additional internal mounting “grabber” grooves to enable secure and adjustable mounting of components (0.400″ nominal thickness, bore containing thin flanges, CF 2.75″ and greater ), and 3) an additional intra-vacuum surface/membrane that can be used to mount parts and assemblies, and/or to create various openings or passages. These features, that can be custom fabricated by the user, can be utilized to create apertures and slits, allow for differential pumping, enable determination of out-gassing rates of a vacuum chamber, and allow calibration of pumping speed for a vacuum pump, just to name a few applications.
The Thin Flanges are available in nominal “gasket to gasket” thickness dimensions (for system planning and layout- includes gasket crushing allowances) of 0.175″ and 0.400″, with actual thickness dimensions of 0.155″ and 0.380″ respectively. CF port dimensions include 1.33″, 2.75″, 4.5″, 6.0″ and 8.0″. Flanges either include a bore (internal circular opening) or have a solid membrane or blank.
