Fundamentals of Monochromatic and Chromatic Aberrations in Optical Engineering

Learn about aberrations, their impact on optical systems, and how to correct them with this free online course.

Publisher: NPTEL
Aberrations in optical systems and engineering fall into two categories named monochromatic and chromatic aberrations and this free online engineering course provides an in-depth study on how to identify aberrations, the components of each category of aberrations, how to trace rays using optical pupils as well as how to optimize aberrations using the optics software for layout and optimization (OSLO).

Description

This free online course on the fundamentals of monochromatic and chromatic aberrations starts by introducing you to ways chief- and marginal rays can be traced through optical pupils in optical systems. You will learn about the meaning of an aberration, the concept of paraxial approximation, the function of the numerical aperture along with what happens when the aperture size decreases in an optical system. 

This optical engineering course then introduces you to the concept of astigmatism as another aspect of monochromatic aberrations and also how it occurs in optical systems. Spherical aberrations using the optics software for layout and optimization (OSLO), how to identify longitudinal aberrations as well as the function of ray intercept curves (or ray-lens intercept curves) in optical systems are then covered. The course content will introduce you to longitudinal chromatic aberrations as it relates to lenses and wavelength in optical systems, the different ways chromatic aberrations can be corrected, then finally working through how to make changes to a system after the aberration has been calculated without affecting the focal length of the system. 

If you are keen on learning about the vast science of optical aberrations in more depth, then register today for this free online course in the Fundamentals of Monochromatic and Chromatic Aberrations in Optical Engineering.
