A lens module arranged on a light-sensing surface of a sensor module is disclosed. The lens module includes at least one lens stacked along an optical axis and the lens includes a lens fixing element and a plurality of lens elements. The lens fixing element is provided with a plurality of through holes each receiving a corresponding one of the lens elements, and an edge of the lens elements is secured to the lens fixing element. According to the present invention, each of the through holes has the same shape as a corresponding one of photosensitive regions of the light-sensing surface, as well as a side wall spaced from the photosensitive region in the direction perpendicular to the optical axis by a relatively uniform gap. In the present invention, there is also provided a camera comprising such a lens module.
A method of forming packaged lens modules is disclosed which includes: securing first ends of a plurality of lens modules equidistantly on a first mold plate; providing a second mold plate matching with second ends of the lens modules and securing the second mold plate on the second ends of the lens modules; filling a black material in gaps between the lens modules; and removing the first and second mold plates after the black material is cured and performing a dicing process. The method can effectively block lens openings to protect lenses from being contaminated and can eliminate the need for adhesive application and removal generally performed on second ends of the lens modules, thereby resulting in time savings and an efficiency improvement. Additionally, a height of the resulting packaged lens modules can be modified for back focal length compensation thereof by changing the size of the second mold plate.

Methods of fabricating self-aligned metal layer structure and optic
A method of fabricating a self-aligned metal layer structure is disclosed. The method includes: providing a substrate including a conductive layer; forming a pattern in the conductive layer; and electroplating the conductive layer to form thereon an electroplated metal layer such that the pattern is directly transferred in the electroplated metal layer in a self-aligned manner. Methods of fabricating optics are also disclosed. The methods are capable of high accuracy in alignment, and the optics can be used in the production of a lens module.
