Distortion correction in ultra wide angle lenses

Free content from Theia Technologies

Today’s megapixel cameras have many advantages as long as you have the right lens for the job. When that includes covering large areas or reducing cost by installing fewer cameras, that lens is a wide angle lens. Until recently only fisheye lenses were available for an ultra wide field of view. However fisheye lenses have significant barrel distortion which causes loss of resolution at the image edges. But Theia's new rectilinear lenses give a different ultra wide view without the barrel distortion or loss of edge resolution of fisheye lenses. These lenses use patented and award-winning Linear Optical Technology(r) to correct barrel distortion in the lens optically, no dewarping software is required.
