Aspheric or Spherical Lenses - Which is best for Vision Applications?Aspheric elements are a popular choice to correct for spherical aberrations and they do this particularly well in wide angle and large aperture optical designs. However, while this design strategy certainly seems to work for infrared and laser optics the advantages for incorporating aspheric optics in machine vision systems can be outweighed by the cost of aspheric lenses typically being twice the price of a standard spherical lens element.
