Many optical aberrations can be easily solved with the right optical design software. For example, OpticStudio from Zemax, the industry-leading optical design software, has many features and functionalities that help correct common aberrations.

In optical design, aberrations occur when light from one point of an object doesn’t converge into or diverge from a single point after transmission through the system. The non-linear terms in Snell’s Law cause deviations from perfect imagery: optical systems that form images will produce images that aren’t as sharp. Optical engineers must correct the aberrations to produce the sharpest images possible.

For example, OpticStudio offers the Full-field Aberration Analysis feature, which allows optical engineers to improve freeform designs by analyzing how various aberrations degrade the image or beam quality of a system across the full field of view. Freeform optical surfaces are a key element in many modern optical systems, used for example in virtual and augmented reality designs. This analysis feature displays aberrations and contributions to image degradation across the full XY field of view. Users can analyze freeform systems, in the same way they would with any other regular sequential system, identifying the change in aberrations across the field of view and getting an indication of how to correct these.
