The CSV300AR.16 Plano-Concave Cylindrical Lens is a 650 to 1000 nm anti-reflection coated, fused silica plano-concave cylindrical lens with a 2 inch (50.8 mm) length and 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.
