Abstract: An optical assembly for a point action camera with a wide field of view includes multiple lens elements configured to provide a field of view in excess of 150 degrees. One or more lens elements has an aspheric surface. The optical assembly exhibits a low inward field curvature of less than 75 microns.
Abstract: An optical assembly for a point action camera with a wide field of view includes multiple lens elements configured to provide a field of view in excess of 150 degrees. One or more lens elements has an aspheric surface. The optical assembly exhibits a low longitudinal astigmatism of approximately 0.3 mm or less.
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: 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 of more of the lens elements has an aspheric surface. The optical assembly exhibits a low ratio of total track length to effective focal length that is less than 8.
