The 20QW40-30AR.16 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 has Newport's AR.16 broadband NIR antireflection coating for a 650 to 1000 nm wavelength range. For demanding applications, such as intracavity laser applications, holography, and multiphoton imaging, this window has a λ/20 surface flatness and 10-5 scratch-dig significantly reducing unwanted scatter.
