This free online course on the fundamentals of monochromatic and chromatic aberrations will begin by introducing you to ways chief ray and marginal ray can be traced through optical pupils in optical systems. You will learn about the meaning of 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 course will also introduce you to the concept of astigmatism as another aspect of monochromatic aberrations along with how it occurs in optical systems. You will learn how to test your knowledge of spherical aberration using the optics software for layout and optimization (OSLO), how to identify longitudinal aberrations as well as the function of ray intercept curves in optical systems.
Finally, this course will introduce you to longitudinal chromatic aberrations as it relates to lenses and wavelength in optical systems. This course will teach the different ways chromatic aberrations can be corrected and how to make changes to a system after the aberration has been calculated without affecting the focal length of the system. Begin this course and improve your knowledge of aberration correction in optical systems.Start Course Now
