WebApr 13, 2024 · The marginal rays come to focus at a point closer to the lens where as the paraxial rays focus at a point which is farther from the lens. Difference between Chromatic aberration and Spherical aberration Difference between chromatic aberration and spherical aberration Essential requirements for achromatic combination of two lens: 1. WebThe use of the lens equation likewise presumes an ideal lens, and that equation is practically true only for the rays close to the optic axis, the so-called paraxial rays. For a lens with spherical aberration, the best approximation to use for the focal length is the distance at which the difference between the paraxial and marginal rays is the ...

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.

WebFigure 4 illustrates a colored ray tracing of a spherical surface. The longitudinal spherical aberration(LSA’) is the difference between the marginal focus (L’ m) and the paraxial focus (L’ p) along the optical axis.
