Aspheric lens is an optical element which have a complex radius of curve, at least one surface is not spherical. The radius of curve is gradually change from center to edge, there have a specified formular of aspheric lens which designed by customers. Compare with spherical lens,      aspheric lens reduces or minimizes spherical aberrations, for example, astigmatism, field curvature, and distortion.
