摘要： A lens module including a lens barrel and a plurality of lenses having refractive power is provided. The lenses are arranged in the lens barrel from an object side to an image side. The lens barrel has an inner-wall surface and an outer-wall surface opposite to each other, and has an air outlet communicating with outside. The air outlet is located between the inner-wall surface and the outer-wall surface. A first lens of these lenses is a lens closest to the object side. The first lens has an object-side optical surface facing the object side. At least over 95% of the surface area of the object-side optical surface of the first lens is exposed to outside, and a material of the first lens is glass. Furthermore, another lens module is also provided.

摘要： 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.
