Cylindrical Lens, Plano-Convex, 50.8x19 mm, 25.4 mm FL, FS, 245-440 nm

UV Coated UVFS Plano-Convex Cylindrical Lenses

The CSX025AR.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 19.0 mm width and an effective focal length of 25.4 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.
