Optical assemblies including dry adhesive layers and associated methods
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.
