Aspherical Lenses Product Information Due to the unique profile, aspherical lenses eliminate monochromatic aberrations (e. g. spherical aberrations) and lead to a better overall image quality. They are increasingly used to replace multi-spherical element assemblies resulting in a weight reduction as well as in a more compact design.
