... However, for any angle of incidence greater than or equal to the critical angle θcrit, all of the incident light reflects (therefore, none refracts), a phenomenon called total internal reflection. See Figure 33.13a. When θa = θcrit, θb nb = 90˚. Therefore, Snell’s law gives na sin θcrit = nb sin 90˚ ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. 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. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
