Newport MKS Plano-Concave Lens, Fused Silica, 50.8 mm, -500 mm EFL, Uncoated SPC040

The SPC040 Fused Silica Plano-Concave Lens is an uncoated 50.8 mm diameter fused silica plano-concave lens with an effective focal length of -500 mm. It is designed to meet the demanding requirements of laser electro-optic applications, Newport's UV grade fused silica precision plano-concave 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.
