Tailored Distortion®: Distortion Correction at Speed of Light

Super wide-angle lenses and fisheye lenses have pronounced barrel distortion. When viewing a flat object, off-axis features are "squeezed" significantly relative to the on-axis ones. This reduces the effective off-axis resolutions. For many applications, it is an undesirable effect. It is possible to post-processing the image to reduce this effect. However post-processing in software reduces the image quality because the missing off-axis information must now be interpolated. We created a new class of super wide-angle and fisheye designs using high precision aspherical elements to reduce the off-axis "squeezing" optically. Comparing with standard f-theta designs, the distortion reduction is on the order of 50%.
