OML is a Test Equipment Company You Can Trust!

Located in the high tech Silicon Valley, the staff at OML have been pioneers in microwave and millimeter wave products since the 1950’s. Our test equipment expertise is traceable to the pioneering spirit at Varian Associates (Solid State Microwave Division), which is globally recognized for the innovative design and manufacture of many of the first microwave products.

In 1991, Charles Oleson started Oleson Microwave Labs to focus on the specialized needs in the emerging millimeter wave test equipment market. In 2004, this successful “start‐up” was incorporated into OML, Inc. where today, as a privately-held company, we continue to evolve as an industry expert and market leader in this growing field.
