Abstract
A spacer includes an object-side surface, an image-side surface, and an outer sidewall. The image-side surface is opposite to the object-side surface. The outer sidewall defines a first cutout and a second cutout. The first cutout and the second cutout penetrate through the object-side surface and the image-side surface. Contours of the first cutout and the second cutout are different from each other.
