The SPX034AR.UF Fused Silica Plano-Convex Lens is a 1 inch (25.4 mm) diameter, fused silica plano-convex lens with an effective focal length of 1000 mm. Coated with a multilayer dielectric coating optimized for anti-reflection and low GVD, the transmission range is 660 to 1380 nm, for lasers such as Spectra-Physics InSight® series. This anti-reflection coated lens is designed to meet the demanding requirements of ultra-fast laser electro-optic applications. Newports UV grade fused silica precision plano-convex lenses are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.
