![]() Radial distortion: Images with radial distortion usually have symmetric distortion due to the symmetry of a lens. Optical engineers must correct the aberrations to produce the sharpest images possible.ĭefocus: The optical system is out of focus, reducing the sharpness of images produced by the system. ![]() The non-linear terms in Snell’s Law cause deviations from perfect imagery: optical systems that form images will produce images that aren’t as sharp. ![]() In optical design, aberrations occur when light from one point of an object doesn’t converge into or diverge from a single point after transmission through the system. ![]()
