Aspherical Lens
In order to eliminate the distortion, spherical aberration, aberration and other problems caused by spherical lenses, it is usually necessary to use multiple spherical lenses. While the use of aspheric lenses can make the surrounding incident light concentrate to the focal plane more ideal, and can save the lens, which is conducive to lightweight.
