Founded in 1974 ios Optics, then OpticFab, produced a single product: beams splitter cubes, in the back of a machine shop in Palo Alto. Shortly thereafter, they moved to a barren 1,000 sq. ft. shop in Santa Clara. In 1980, the company was purchased by former Spectra Physics manufacturing engineer Douglas Fitzpatrick who grew the company by increasing the product and service offerings over the next three decades.

Today, the company is known as an industry leader in custom precision optics and occupies a two acre lot just a half mile away from its humble beginnings. Although the size of the company has changed - the character has not. Our team members are experts in the optics industry and possess a true passion for the precision optical products they produce. Our management team is comprised of industry veterans having worked on thousands of projects; this experience provides a deep understanding of the industries we serve.

ios Optics distinguishes itself from the competition by consistently anticipating and responding to the needs of its customers. We are both a supplier and a partner committed to the long term success of our clients.
