Lens Aberrations
Avoiding Defects in Imagery
A perfect lens can produce a perfect image. But seven primary lens aberrations can blur or distort the image instead, and they should be considered when creating an optical system. A lens collects light from a point on an object and focuses it to a corresponding conjugate point on an image. Under most conditions, the lens fails at this task because of some error in the precision with which it focuses this light. Rather than a true point image, the lens produces a blur circle. It is the...
