Cylindrical Lens, Plano-Convex, 50.8x25.4 mm, 50.2 mm FL, FS, Uncoated

The CSX050 Plano-Convex Cylindrical Lens is an uncoated, fused silica, plano-convex cylindrical lens with a 2 inch (50.8 mm) length, a 1 inch (25.4 mm) width, and an effective focal length of 50.2 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.
