Abstract: An optical assembly for a point action camera with a wide field of view has multiple lens elements configured to provide a field of view in excess of 150 degrees. One or more lens elements has an aspheric surface with an approximately 30 microns or less sag and an approximately 25 microns/millimeter or less aspheric sag slope.
Abstract: A projection zoom lens assembly for a digital cinema projection system includes three optical groups. A first optical group includes one or more wide angle lenses for projecting digital cinema images. A second optical group includes a set of zoom optical groups each comprising two or more lenses, including a first independently movable zoom group, a second independently movable zoom group, and a third zoom group. A third optical group includes multiple lenses for receiving images for projection.

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.
