Rayotek Capabilities Overview

Rayotek Sight Windows (RSW) is the end result of a natural evolution of business and technology that began at the parent company, Rayotek Scientific, Inc. (Rayotek). As an international leader in glass, sapphire and materials integration technology, Rayotek had received numerous requests to engineer long lasting, high-end sight windows for hostile environments. Though there are many companies that make sight windows, few, if any, could meet the rigorous requirements of Rayotek customers. And even more importantly, none that could provide the extensive engineering support Rayotek delivers.

After 15 years of making the highest quality, best engineered sight windows as a sideline, Rayotek decided to formalize its commitment to quality Sight Window production and Rayotek Sight Windows was born.

Although Rayotek Sight Windows began in 2006 as a department, RSW formally became its own entity in 2013 with the launch of its own web site and independent business address. RSW is now its own division, partnering with Rayotek, to form a powerful technology alliance.
