Optical aberrations are deviations from a perfect, mathematical model. It is important to note that they are not caused by any physical, optical, or mechanical flaws. Rather, they can be caused by the lens shape itself, or the placement of optical elements within a system, due to the wave nature of light. Optical systems are typically designed using first-order or paraxial optics in order to calculate image size and location. Paraxial optics does not take into account aberrations; it treats light as a ray and therefore omits the wave phenomena that cause aberrations. For an introduction on optical aberrations, view Chromatic and Monochromatic Optical Aberrations.

Recognizing optical aberrations is very important in correcting for them in an optical system, as the goal is to get the system to be diffraction limited. Optical and imaging systems can contain multiple combinations of aberrations, which can be classified as either chromatic or monochromatic. Correcting aberrations is best done in the design stage, where steps such as moving the aperture stop or changing the type of optical lens can drastically reduce the number and severity (or magnitude) of aberrations. Overall, optical designers work to reduce first and third-order aberrations primarily because reducing higher-order aberrations adds significant complexity with only a slight improvement in image quality.

Determining what aberrations are present in an optical system is not always an easy task, even when in the computer analysis stage, as commonly two or more aberrations are present in any given system. Optical designers use a variety of tools to recognize aberrations and try to correct them, often including computer-generated spot diagrams, wave fan diagrams, and ray fan diagrams. Spot diagrams illustrate how a single point of light would appear after being imaged through the system. Wave fan diagrams are plots of the wavefront relative to the flattened wavefront where a perfect wave would be flat along the x-direction. Ray fan diagrams are plots of points of the ray fan versus pupil coordinates. The following menu illustrates representative wave fan and ray fan diagrams for tangential (vertical, y-direction) and sagittal (horizontal, z-direction) planes where $ \small{H = 1} $ for each of the following aberrations: tilt $ \left( \small{W_{111}} \right) $, defocus $ \left( \small{W_{020}} \right) $, spherical $ \left( \small{W_{040}} \right) $, coma $ \left( \small{W_{131}} \right) $, astigmatism $ \left( \small{W_{222}} \right) $, field curvature $ \left( \small{W_{220}} \right) $, and distortion $ \left( \small{W_{311}} \right) $. Simply select the aberration of interest to see each illustration.

Recognizing aberrations, especially in the design stage, is the first step in correcting for them. Why does an optical designer want to correct for aberrations? The answer is to create a system that is diffraction-limited, which is the best possible performance. The aberrations of diffraction-limited systems are contained within the Airy disk spot size, or the size of the diffraction pattern caused by a circular aperture (Figure 1).

After a system is designed and manufactured, aberrations can be observed by imaging a point source, such as a laser, through the system to see how the single point appears on the image plane. Multiple aberrations can be present, but in general, the more similar the image looks to a spot, the fewer the aberrations; this is regardless of size, as the spot could be magnified by the system. The following seven examples illustrate the ray behavior if the corresponding aberration was the only one in the system, simulations of aberrated images using common test targets (Figures 2 - 4), and possible corrective actions to minimize the aberration.

After defining the different groups and types of chromatic and monochromatic optical aberrations, the difficult part becomes recognizing them in a system, either through computer analysis or real-world observation, and then correcting the system to reduce the aberrations. Typically, optical designers first put a system into optical system design software, such as Zemax® or Code V®, to check the performance and aberrations of the system. It is important to note that after an optical component is made, aberrations can be recognized by observing the output of the system.
