The 20QW40-30 Laser-Grade Parallel Window is parallel to less than 30 arc sec for minimal transmitted beam deviation. This 2 inch (50.8 mm) diameter UV Grade Fused Silica window is 10 mm thick. It is uncoated. For demanding applications, such as intracavity laser applications, holography, and multiphoton imaging, this window has a &lambda,/20 surface flatness and 10-5 scratch-dig significantly reducing unwanted scatter.
