The rule of adaxial image formation is studied, of the transmission light and reflected light through the two optical surfaces L_1 and L_2 of the biconvexlens.
The optical aberration difference between the biconvex Fresenl lens and the plane-convex Fresenl lens was investigated by designing a large aperture Fresenl lens.
