Cylindrical Lens, Plano-Convex, 50.8x50.8 mm, 300 mm FL, FS, 245-440 nm
The CSX300AR.10 Plano-Convex Cylindrical Lens is a 245 to 440 nm anti-reflection coated, fused silica, plano-convex cylindrical lens with a 2 inch (50.8 mm) length, a 2 inch (50.8 mm) width and an effective focal length of 300 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's UV grade fused silica precision cylindrical lenses are polished to tight tolerances to ensure minimum wavefront distortion. UV grade fused silica will not fluoresce under UV light and is resistant to radiation. And for high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage. Specifications
