Overview

Eulitha is a Swiss photolithography company that makes lithography equipment and solutions for photonics manufacturing. Established in 2006, it builds tool platforms and patterning solutions around its patented Displacement Talbot Lithography (DTL) technology, which patterns high-resolution, low-cost, periodic nanostructures. The company was started with the idea of developing new optical lithography technologies for cost-effective patterning of periodic nanostructures over large areas for emerging applications, enabling devices in fields such as Augmented Reality (AR), telecommunication, lasers, and biological sensors. Its headquarters is located near Zürich in Würenlos, Switzerland, housing primary equipment production facilities and hardware/software development labs; it also has offices near Seattle in Redmond, Washington, United States, and in Beijing, China.

History

Eulitha was established in 2006. The company was started with the idea to develop new optical lithography technologies for cost-effective patterning of periodic nanostructures over large areas for emerging applications. It makes lithography equipment and solutions for photonics manufacturing, building new tool platforms and discovering innovative patterning solutions to match developing market needs, built around IP-protected Displacement Talbot Lithography. Its headquarters is located near Zürich in Würenlos, Switzerland, and houses primary equipment production facilities and hardware/software development labs. It also operates a USA office near Seattle in Redmond, Washington, focused on equipment engineering and field support for North American customers and markets, and a China office in Beijing providing localized support and driving regional growth.
