Optical Aberrations: Understanding and Minimizing

This lecture covers the five types of 3rd order monochromatic aberrations, the approximation of spherical surfaces by paraboloidal surfaces, and the dispersion of light. It explains the two classes of optical aberrations - monochromatic and chromatic, focusing on spherical aberration and astigmatism. The lecture also delves into the concept of field curvature, the effects of chromatic aberration, and the photometric and colorimetric systems used in optics. Practical methods to minimize aberrations, such as using different lens shapes and materials, are discussed in detail.
