Since the company's inception as Johnsen Machine Company in 1961, this privately owned firm has enjoyed an enviable reputation for excellence.

Now, as Johnsen Ultravac Inc. the company continues to uphold and maintain these lofty standards. Transforming customer needs into technically superior machined and manufactured instruments for science, business and industry, Johnsen Ultravac delivers expert solutions for a variety of applications.

The core of our expertise lies in the design and manufacture of UHV (Ultra High Vacuum) chambers and systems. As such, Johnsen Ultravac is one of the leading suppliers of ultra high vacuum products around the globe. The company is also recognized internationally within the Synchrotron community for meeting the highest technical standards necessary for this pioneering research tool.

From beam line components to linear motion devices, XYZ manipulators and vacuum systems, Johnsen Ultravac offers a wealth of experience and precision manufacturing capabilities. Whether we provide customized solutions or standard modular components, understanding our clients' critical requirements and responding to their challenges is our mandate.

Our clients come from leading corporate, academic and government research and production laboratories located throughout North America, Europe and Asia. From concept to design and manufacture, Johnsen Ultravac leads the way in technologically advanced vacuum systems, components and instrumentation.


At Johnsen Ultravac Inc. (JUV) we strive to build the highest quality, most reliable, vacuum equipment available anywhere. Our vacuum equipment delivers total value to our global customers in terms of payback, low maintenance, flexibility and durability.

If your materials research requires an ultra high vacuum chamber it may be of interest to know that our UHV chambers routinely operate in the 5 x 10E-11 Torr base pressure range.

If your research requires complex 6-axis XYZ manipulators or Linear translators JUV offers the widest range in UHV instrumentation. With optional electron beam heating and Helium cooled cryostats our modular sample holder arrangements are leading the industry in temperature range (10° K to 1,500° K), motion, accuracy and repeatability.

If Synchrotron Radiation Instrumentation is your interest the JUV SRI Product line for Light Sources includes Monochromators for X-ray Beam lines, Front-ends, Photon and Safety Shutters. Other SRI products include Collimators, Mask assemblies, Mirror chambers and Safety Shutters.

If your research is in Electro-photonic, Opto-electronics or Semi-conductor devices the JUV 6000 series combine the latest E-Beam Evaporation, ECR-CVD and ICP-CVD deposition technology.

If your research is in Materials Science, Nano Technology or Super Conductivity the JUV 6100 series combine the latest in RF-DC Sputtering, RF-ICP Plasma Spray and Pulsed LASER (PLD) deposition technology.

If you require products for testing of Satellite Instruments such as IR Sensors our products for the Aerospace Industry include Blackbodies, Bench coolers and Space Simulation Systems.

Also, with our staff of engineers with vacuum and cryogenic experience JUV leads the industry in CUSTOM design and manufacturing capabilities. Why not put the JUV team to work for you.
