show the imaging area cleared spherical aberration is demonstrated with the small helical coil in a light bulb as the object the image back is
a reflection by a parabolic mirror behind the lamp initially the entire lens opening is used the image is of moderate quality when
only the central part of the lens is used a
clear picture received that
is however if only the outer regions of the lands they used the image occurs much
closer to the lens this image
has far poorer quality and also shows chromatic aberration
