Optical assembly for a wide field of view point action camera with a low sag aspheric lens element

摘要

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.

1. An optical assembly for a point action camera having a wide field of view, comprising multiple lens elements, including an aspheric surface with an approximately 30 microns or less sag and an approximately 25 microns/millimeter or less aspheric sag slope, configured to provide a field of view in excess of 150 degrees, and
wherein said aspheric surface includes a point of inflection of maximum sag at a radial distance from a center of said aspheric surface that is less than approximately 0.85× a center to edge radius of said aspheric surface.
