Get to know the Optical Aberrations present in your Image

By Stuart W. Singer and Jim Sullivan

This article explains why simply looking at a Modulation Transfer Function (MTF) plot is not enough to fully evaluate a lens or diagnose imaging issues. While MTF data accounts for all optical aberrations, it doesn’t reveal which specific aberrations are affecting the image. To achieve optimal optical performance, understanding individual aberrations is crucial. The article also discusses various types of aberrations like spherical and chromatic, how they vary with lens settings, and the importance of using ray aberration plots for more accurate analysis.
