FIELD

The subject matter herein generally relates to imaging.

BACKGROUND

In many lens modules, spacers are necessary for maintaining gaps between adjacent lenses. However, due to the process of molding the spacer, it is difficult to achieve geometric precision when placing the spacers. As a result, the inner edges of the spacer usually form a certain curvature or irregular shape which scatters light and reduces the image quality of the lens modules.

Therefore, there is room for improvement.
