Achromatism in lenses - Ray Optics, Physics - eSaral

Hey, do you want to learn about achromatism in lenses? If yes. Then keep reading Achromatism: We have just that when a white object is placed in front of a lens, then its images of different colors are formed at different positions and are of different sizes. These defects are called 'longitudinal chromatic aberration' and 'lateral chromatic aberration' respectively. If two or more lenses be different colors are in the same position and of the same size, then the combination is called 'achromati...
