Spherical Aberration
Spherical aberration occurs when light rays passing through a lens do not converge at the same point. This results from the spherical shape of standard lenses. Since the light rays hitting the lens at different places focus at different distances, this causes blur and reduces image quality, especially in strong lighting.
In lenses with spherical surfaces, rays from the edge focus nearer than those from the center. This variance in focus points across the lens surface degrades the image. It can cause softness in images that cannot be eliminated by simply adjusting the focus. Modern lens designs often use aspherical elements to reduce this effect.
Aberration of Lens
Aberration of the lens refers to the failure of a lens to produce a perfect image. It occurs due to the lens’s geometry and light’s physical properties. There are several lens aberrations, each affecting the image in different ways.
In this article, we will discuss lens aberration, its types, corrections methods, and many more in detail.
