    If your application requires you to reduce the amount of aberrations present in a standard spherical lens, Edmund Optics ® can also modify one of our standard spherical PCX lenses into an aspheric lens. By introducing a negative conic constant and removing about 400 microns of material, you will end up with an asphere that significantly outperforms the original spherical lens.
