See paraxial approximation. You have instead used marginal rays in your graphs which are quite far from the principal axis and will thus never converge properly at one fixed point. This can be easily fixed by using parabolic mirrors which will by design obey the above rule. blister medical name

WebIn units of the paraxial blur diameter (Λ=0), the blur size is 0.385 for Λ=2 (marginal focus), 0.25 for Λ=1.5 (circle of least confusion) and 0.5 for Λ=1 (diffraction focus). The relative wavefront error - either P-V or RMS - for any point between the two foci, in units of the error at the paraxial or marginal focus, is also constant, given by: WebIn the paraxial approximation where θ∼=0, the refraction equation simpliﬁes to: n 1θ 1 = n 2θ 2 =⇒ θ 2 θ 1 = n 1 n 2 =⇒θ 2 = n 1 n 2 θ 1 In words, the ray angle after refraction is proportional to that before refraction. Power The value of a lens or lens system is due to its ability to “redirect” rays by changing their direction.

Besides, the focus position of a lens depends on the distance, with respect to the optical axis, of the ray arriving at the lens. Namely, the focus positions are different for the meridional, marginal and paraxial rays ...
