Aberrations In an ideal optical system, all rays of light from a point in the object plane would converge to the same point in the image plane, forming a clear image. The influences which cause different rays to converge to different points are called aberrations. Summary of aberrations and corrections	Index Lens concepts

Summary of Aberrations In an ideal optical system, all rays of light from a point in the object plane would converge to the same point in the image plane, forming a clear image. The influences which cause different rays to converge to different points are called aberrations. Aberration Character Correction 1. Spherical aberration Monochromatic, on- and off- axis, image blur Bending, high index, aspherics, gradient index, doublet 2. Coma Monochromatic, off-axis only, blur Bending, spaced doublet with central stop 3. Oblique astigmatism Monochromatic, off-axis blur Spaced doublet with stop 4. Curvature of field Monochromatic, off-axis Spaced doublet 5. Distortion Monochromatic, off-axis Spaced doublet with stop 6. Chromatic aberration Heterochromatic, on- and off-axis, blur Contact doublet, spaced doublet
