Lecture

Optical Aberrations: Spherical and Chromatic

Description

This lecture covers optical aberrations, focusing on spherical aberration and chromatic aberration. Spherical aberration is discussed in terms of longitudinal and transverse spherical aberration, as well as its correction methods. The lecture also explains astigmatism and coma aberrations, and how to minimize them. Additionally, it delves into field curvature and the Petzval surface. Chromatic aberration is explored through the dispersion of light in different materials, leading to the explanation of the achromatic doublet for its correction.
