Aspheric Plano Convex Lens

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.
