Optical Window, Parallel, N-BK7, 25.4 mm, λ/20, Uncoated
The 10BW40-30 Laser-Grade Parallel Window is parallel to less than 30 arc sec for minimal transmitted beam deviation. This 1 inch (25.4 mm) diameter N-BK7 window is 6 mm thick. It is uncoated. 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.
