Rajesh Kumar
Defects of images, chromatic and monochromatic aberration , Spherical aberration, astigmatism,COMA. Curvature defects and distortion defect. Marginal rays focus near to Mirror and lens paraxial rays focus and theoretical focus practically we have to focus and the distance between these two focus gives magnitude of aberrations violet light focus near to Lens due to more deviation. Red light focus away from lens.distion defects extended objct becomes curved image.
