Seidel aberrations

Seidel aberrations are optical imperfections that occur in lenses, affecting the clarity of images produced by cameras, microscopes, and other optical devices. These aberrations arise from the lens's inability to focus all colors of light evenly and can result in issues like blurriness, distortions, or color fringing. The main types include spherical aberration (blurring due to shape), coma (asymmetrical distortion), astigmatism (varying focus in different directions), field curvature (image curvature), and distortion (incorrect shape of the image). Understanding and correcting these aberrations is crucial for improving image quality in optical systems.
