The OQOPW20-C Parallel Window is parallel to less than 30 arc sec for minimal transmitted beam deviation. This 20mm diameter BK 7 window is 3 mm thick.For demanding applications, such as intracavity laser applications, holography, and multiphoton imaging, this window has a λ/4surface flatness and 40-20 scratch-dig significantly reducing unwanted scatter.
