Suppose we have a thin double-convex lens (also called a spherical lens) with surface radii given by Rį and R2 as shown (remember by convention, Ry is positive and R2 is negative if they are convex) in air. The thickness A is negligible. (-R2) R1 ital (a) Show that the complex amplitude transmittance of this lens is given by x2 + y2 t(x, y) = họ exp|jko 2f (, y) , |*** } = (n - where 1 1 1 (n-1) = f R1 R2
(c) Suppose the lens in (a) is placed at position z = Z1, where 21 > 2o. Write an expression for the resulting wave's complex amplitude U'(x, y, z) immediately after the lens, i.e., z = zz. =
