Abstract: An optical assembly includes an image sensor, a lens module disposed over the image sensor in a first direction, a transparent glue layer, and a transparent dry adhesive layer formed of a different material than the transparent glue layer. Each of the transparent glue layer and the transparent dry adhesive layer are disposed between the image sensor and the lens module in the first direction. Each of the transparent glue layer and the transparent dry adhesive layer are optically coupled in series with the image sensor and the lens module. A method for forming an optical assembly includes joining an image sensor and a lens module using a transparent glue layer and a transparent dry adhesive layer formed of a different material than the transparent glue layer.

Abstract: A trenched-substrate based lens manufacturing method includes depositing lens material on a first side of a substrate, wherein the first side of the substrate has a plurality of trenches. The method further includes shaping a plurality of lens elements from the lens material. The method includes shaping the plurality of lens elements, on a respective plurality of surface portions of the first side, by contacting a mold to the first side. Each of the surface portions are adjacent a respective one of the trenches. Additionally, the method includes accommodating an excess portion of the lens material in the trenches. A lens system, manufactured using this method, includes a substrate with a planar surface and a trench embedded in the planar surface. The lens system further includes a lens element molded on the planar surface adjacent to the trench.

Abstract: A wafer-level lens forming method for forming an aperture wafer wherein the aperture wafer is stacked with one or more lens wafers to form apertured lens systems. The aperture wafer is formed by lithographically depositing an opaque layer on a transparent film, which is supported by a substrate. The aperture wafer is stacked with one or more lens wafers, and appropriate spacing between the wafers is set with spacer wafers. The substrate is removed, and the lens and aperture wafers are adhered together in a stack to form an optical system. The method avoids accumulation of residual material on the lens during the opaque-layer deposition process. The resulting optical system benefits from added flexibility of the lens system design due to the ability to locate the aperture with respect to one or more lenses independently of the lens wafers.
