Glass to metal seals

Glass-to-metal seals are the solution if you’re putting optical devices in the field that must perform reliably – every time – even after prolonged exposure to challenging conditions. We have made it our mission to provide world class seals for optical devices that deliver the reliable product lifetimes our customers depend on.

Our brazed glass-to-metal seals produced from start to finish in-home, resist extreme temperatures, pressures, humidity levels and even  repeated chemical exposure or explosive environments.  We marry these seals with highly accurate laser welding to achieve truly hermetic performance for optical assemblies.

OEM customers bring us their toughest requirements for systems that have to deliver top performance under harsh environmental conditions. Time and time again, our technology solves problems considered insurmountable.


We hold certification to ISO13485:2016 and ISO9001:2015. Our FDA registration and U.S. manufacturing operations support the strictest regulatory transparency requirements for our customers.
