Inability of the lens to focus on light rays
WebThe inability of the lens to bring all of the colors into a common focal plane results in a slightly different image size and focal point for each of the three predominant wavelength groups. The result is a colored fringe or halosurrounding the image, with the halo color changing as the focal point of the objective is varied. Chromatic Aberration WebApr 5, 2024 · When marginal ray and paraxial rays do not converge at the same point, on a spherical surface, either mirror or lens, it is known as the spherical aberration. So, the correct answer is “Option B”. Note: Different types of spherical lenses are: Convex or Converging Lenses: They are thick in the middle and thin at the edges.
