Bi-Convex Lens, Fused Silica, 50.8 mm Diameter, 100 mm EFL, 245-440nm

The SBX055AR.10 Fused Silica Bi-Convex Lens is a 50.8 mm diameter, 245 to 440 nm anti-reflection coated, fused silica bi-convex lens with an effective focal length of 100 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's UV grade fused silica precision bi-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.
