Omley Industries, Inc.

Sapphire is a remarkable material combining optical clarity, high strength and electrical isolation. With our many years of service, Omley has experience brazing sapphire in all kinds of geometries and for a wide array of applications. Some of the more common applications include vacuum viewports, protective optical shields, sapphire-tipped process probes, CCD enclosures , lamp housings, and high pressure windows. Sapphire can also be used as an insulator material in feedthrough and line-break applications.

Achieving a reliable hermetic seal with Beryllium is no easy task, but Omley Industries has been successfully brazing Beryllium for years. Vacuum brazed beryllium X-Ray windows are robust, yielding stronger joints than diffusion bonding. They will withstand repeated high temperature cycles and are vacuum compatible. Hermetic windows can be brazed using foil as thin as .003”(.075mm). Windows can be brazed into standard flange styles or into custom mounts. Beryllium structures can also be brazed. While stainless steel is the most common pairing with Beryllium, other metals can be brazed to Beryllium as well.

Metal-to-metal vacuum brazing opens up many design possibilities. Often, design features are not conducive to welding. Some combinations of metals, are not weldable. Vacuum brazing allows materials to be joined in a very clean manner with very robust results. The benefits of vacuum brazing include:  Full joint penetration—no virtual leaks.  No induced contamination or trapped oxides.  Allows the joining of multiple metals.  Allows the joining of metals that are difficult or impossible to weld or braze in other atmospheres.  Price competitive with welding.  The vacuum brazing process cleans metal surfaces of any organic contaminants.  Most metals can be vacuum brazed.

Helping customers design and manufacture feedthrus and insulators for OEM and special applications is one our most significant strengths. Off-The-Shelf components do not work for all applications. When custom components are required, Omley Industries is there to put our extensive experience to work for you. Feedthru designs can range from the small micro-amp signal feedthrus to applications requiring the transmission of several thousand amps. High amperage designs can include water cooling. Feedthrus can be built to operate in atmospheres ranging from ultra-high vacuum to very high pressure.
