Who we are and what we do:

Zemax empowers thousands of optical engineers to bring new technologies to life. As the global leader in optical and illumination design software, Zemax touches nearly every optical and illumination space, from virtual reality systems to moon exploration to extreme-sport videos to self-driving cars to digital retina mapping. There is a reason that 50% of all optical engineering jobs require Zemax software experience!

Since 1991, Zemax has been driven by people passionate about the optical design space, and that legacy continues to this day. In the last four years, Zemax has seen dramatic growth, both in sales and headcount. The recent strategic investment by EQT Partners positions the company to triple our sales in the next 3-5 years. Headquartered in Kirkland, WA, Zemax has expanded sales and customer success support globally with operations in London, Shanghai, Taipei, and Japan.

OpticStudio is Zemax's core product, the industry standard for design and simulation software for optical and illumination designers, engineers, and researchers worldwide. In early 2016 we launched OpticsBuilder for SolidWorks, an add-in to enable mechanical engineers to seamlessly package optical systems in the environment they know best. A version of OpticsBuilder for Creo Parametric was subsequently launched in 2018 as we looked to increase our support for the mechanical engineering ecosystem. As always, we're focused on decreasing time to market, enabling faster turn-around from concept to product development.
