Newport MKS Plano-Convex Lens, Fused Silica, 50.8 mm, 200 mm EFL, Uncoated SPX049

The SPX049 Fused Silica Plano-Convex Lens is an uncoated, 2 inch (50.8 mm) diameter, fused silica plano-convex lens with an effective focal length of 200 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's UV grade fused silica precision plano-convex lenses are polished to tight tolerances using master test plates 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.
