The SPX529RAR.S Fused Silica Plano-Convex Lens is made of high purity UV Grade Fused Silica Corning 7980 0A material. It is 12.7 mm diameter plano-concvex lens with an effective focal length of 50 mm. The front and back surfaces have sub-wavelength nano-textures etched into the surface creating a high performance anti-reflection effect. The RAR.S pattern is optimized for 250-550 nm. The surface quality of the lens is 10-5 scratch dig with high damage thresholds.
