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.
