Manufacturing and Assembly Services

Assembly and fabrication services:

ColdQuanta now offers precision bonding and ceramics machining services.

Anodic bonding and optical contacting:

ColdQuanta offers a breadth of experience and expertise in precision bonding of optical materials.  In particular, we are able to offer services of anodic bonding of glass and silicon, as well as direct glass to glass bonding (optical contacting).  Performed in our dedicated clean room, both of these processes allow for the production of permanent hermetic seals between materials without the use of epoxies, frits, or adhesives; making them ideal for ultra-high vacuum applications.  We also have experience using these techniques to fabricate structures with optical components for use in UHV environments.



Ceramics machining:

ColdQuanta has dedicated manufacturing facilities for fabrication of complex structures in difficult-to-machine materials, such as silicon, sapphire, and scientific glasses.  With the use of vertical CNC milling machines, our unique process enables us to create non-conventional geometry within brittle materials, and to offer solutions to projects that most shops would turn away.  We specialize in fabricating structural or optical components for use in UHV environments.
