The 20Q20XAR.18 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 2 inch (50.8 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. Newport's AR.18 broadband IR antireflection coating is applied for a 1000 to 1550 nm wavelength range.
