Here, z is the profile height as a function of the radial coordinate h (distance from the optical axis). K is the conic constant, which can be used to obtain certain typical shapes (which may be modified further with the additional terms):. For K = 0, the formula describes a spherical surface with the inverse radius of curvature C.; K = −1 results in a parabolic shape.
