Abstract:
An optical assembly for a wide field of view digital camera includes, from object end to image end, first and second optical groups separated by an aperture stop. The optical assembly is configured to provide images with TV distortion that is less than 16. The first optical group includes two or more lens elements, including a first lens element having a largest diameter among the multiple lens elements to collect light at said wide field of view. The second optical group includes a doublet, which is configured to compensate for oblique aberrational error, and an aspheric lens element, which is configured to compensate for astigmatism error.
