Abstract:
A wafer-level lens system includes one or more wafer-level lenses, each of the one or more wafer-level lenses having a substrate with opposing first and second surfaces, a first lens element of a first material and disposed on the first surface, and a second lens element of a second material and disposed on the second surface, wherein, for at least one of the one or more wafer-level lenses, the first material is different from the second material. Another wafer-level lens system includes three wafer-level lenses optically coupled in series with each other, each of the three wafer-level lenses having a substrate with opposing first and second surfaces, a first lens element disposed on the first surface and having an aspheric surface facing away from the first surface, and a second lens element disposed on the second surface and having an aspheric surface facing away from the second surface.
Abstract:
A three-piece all-aspheric adapter fisheye lens includes a negative meniscus lens, a biconvex lens, and a biconcave lens positioned between the negative meniscus lens and the biconvex lens. The lenses are coaxial and are arranged with an exit pupil to cooperatively generate an image with a camera lens that has greater field of view than the camera lens alone when the exit pupil is coplanar and coaxial with an entrance pupil of the camera lens. Each lens has an aspheric object-side surface and an aspheric image-side surface.
