A lens including a filter, an aperture stop, and a lens set sequentially arranged along a first direction is provided. The filter includes a central region and a peripheral region. The central region has a first light transmission band for a wavelength range of a visible light and a second light transmission band for a wavelength range of an infrared light. The peripheral region surrounds the central region. The peripheral region has a third light transmission band for the wavelength range of the infrared light and is substantially opaque to the visible light, and an area of one portion of the central region surrounded by the peripheral region is tapered toward the first direction.
