lens_petzval_radius — OPTICS lenssolve op

使い方

像空間のペッツバール半径: 3 次の像面湾曲を消す像面の曲率半径(table)。

R_p = -1 / (n' P) with the Petzval sum P = sum c (n' - n) / (n n') over the refracting surfaces (an ideal lens adds nothing, as in seidel_coefficients); for a thin lens of index N in air this is -N f: the surface bends towards the lens. Positive R follows the library’s convention (centre to the right), so a positive lens has a negative Petzval radius. Returns {"radius", "sum", "n_image"} (radius is inf when the sum is zero). Systems with a mirror are refused.

Example::

lens_petzval_radius(lens)["radius"]        # about -n f for a thin lens
