Abstract: An optical power prism that may be used in folded lens systems that consists of a glass prism and a glass lens attached to a surface of the prism using a thin layer of optical glue or by optical contact. The glass lens does not have a flange and thus the prism can be smaller than prisms used in conventional power prisms with the same lens effective area, thus reducing the Z-height of the power prism when compared to conventional power prisms. An optical glass may be used for the lens that has a higher refractive index than can be provided by optical plastic which allows the lens to be thinner than plastic lenses. The lenses may be formed by molding a glass wafer to form lens shapes on a first surface of the wafer; the molded wafer is then ground from a second surface to singulate the lenses.

Abstract: Various embodiments include an aperture stop for a camera with folded optics. In some examples, a folded optics arrangement of the camera may include one or more lens elements and one or more light path folding elements (e.g., a prism or a mirror). The aperture stop may be an elongated aperture stop. According to various examples, one or more prisms of the folded optics arrangement may have an elongated dimension in the same direction as an elongated dimension of the elongated aperture stop. In some embodiments, the aperture stop may be located between a prism and a lens group of the folded optics arrangement. In some embodiments, the aperture stop may be located proximate an optical element that optically powers a prism of the folded optics arrangement.

Abstract: Various embodiments disclosed herein include camera equipment having a refractive index layer that causes internal reflection close to an image sensor of the camera. In some examples, internal reflection may occur at a boundary formed with the refractive index layer and located between an image sensor and an upper surface of a lens of the camera. The boundary may be formed between the refractive index layer and another material located between the refractive index layer and the image sensor, wherein the refractive index layer has a lower index of refraction than other material between the refractive index layer and the image sensor. The boundary formed with the refractive index layer may cause light to be reflected back toward the image sensor to improve image quality of images captured by the image sensor.
