Geometric Aberrations
Geometric aberrations are optical distortions that occur in lenses and mirrors, affecting the clarity and accuracy of images. These aberrations arise when light rays do not converge at a single point, leading to issues like blurriness or distortion. Common types include spherical aberration, coma, and chromatic aberration, each impacting image quality in different ways.
These aberrations can be particularly problematic in high-precision applications, such as telescopes and cameras. To minimize their effects, optical designers often use specialized lens shapes or coatings. Understanding geometric aberrations is essential for improving the performance of optical systems and achieving clearer images.
