Plano-Concave Lens, Nano-Textured Fused Silica, 12.7 mm, -44.4 mm EFL, 500-1100 nm

Nanotexture Surface Plano-Concave Lenses

The SPC502RAR.L Fused Silica Plano-Concave Lens is made of high purity UV Grade Fused Silica Corning 7980 0A material. It is 12.7 mm diameter plano-concave lens with an effective focal length of -44.4 mm. The front and back surfaces have sub-wavelength nano-textures etched into the surface creating a high performance anti-reflection effect. The RAR.L pattern is optimized for 500-1100 nm. The surface quality of the lens is 10-5 scratch dig with high damage thresholds.
