lens is biconvex. The lens shape is shown along the vertical axis.
3.3.1 Summary of the Thick Lens
For a thick lens the optical power is approximately the sum of the powers of the
individual surfaces, provided the lens is not extremely thick .
The spacing of the principal planes of a glass lens is approximately one-third of the
thickness of the lens.
For a symmetric biconvex or biconcave lens, the principal planes are symmetrically
placed around the center of the lens.
For a plano-convex or plano-concave lens, one principal plane
