Cylindrical Lens, Plano-Concave, 50.8x19 mm, -25.4 mm FL, FS, Uncoated

Uncoated UVFS Plano-Concave Cylindrical Lenses

The CSV025 Plano-Concave Cylindrical Lens is an uncoated, fused silica plano-concave cylindrical lens with a 2 inch (50.8 mm) length and a 0.75 in. (19.05 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.
