WebOne of the most precise optical instruments is the human eye, and in the human eye, you have a lot of parts. Up front you've got the cornea. This acts like the main lens. This is the front lens here. This does most of the bending of the light, but you've also got this inner lens that's just called the lens.

WebSpherical Aberration. For lenses made with spherical surfaces, rays which are parallel to the optic axis but at different distances from the optic axis fail to converge to the same point. For a single lens, spherical aberration can be minimized by bending the lens into its best form. For multiple lenses, spherical aberrations can be canceled by ...

WebAn optical aberration is a property of an optical system that causes the light that goes through it to spread rather than to focus on a point. In other words, aberrations are imperfections of optical systems. They are not caused by defects in the making of devices but rather because of their physical conditions.

WebAberration can be defined as a departure of the performance of an optical system from the predictions of paraxial optics. [2] In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system.
