The 10Q20XAR.14 High-Energy Laser Windows is specially designed to eliminate losses in vacuum cell applications and can be used as a vacuum window, convection barrier, or interferometer compensator plate. This 1 inch (25.4 mm) diameter optic is precision polished, select grade fused silica coated with hard refractory multilayers for very high damage threshold. A 30 arc min wedge between the polished faces eliminates fringe patterns and cavity feedback. Newports XAR.14 broadband VIS antireflection coating is applied for a 430 to 700 nm wavelength range.
