When measuring thin lens focal length, moving like a screen, found in a certain light, as a seat is relatively clear, but could not determine the location of the most clear, this is because the non-pure monochromatic light source and can not meet the conditions of paraxial light caused that the aberrations of the phenomenon. Monochromatic aberrations divided into two types of aberrations and chromatic aberration.Aberrations, paraxial light, non-pure monochromatic nature 谢谢采纳·!
