An optical element (100) and an optical module (200) are provided. The optical element (100) comprises a transparent substrate (110), an array microlens layer (120) and a Fresnel lens layer (130). The array microlens layer (120) and the Fresnel lens layer (130) are stacked on the transparent substrate (110), or the array microlens layer (120) and the Fresnel lens layer (130) are respectively located on two opposite sides of the transparent substrate (110), wherein the Fresnel lens layer (130) is used for adjusting an emergent angle of an incident light beam, and the array microlens layer (120) is used for homogenizing a light beam emitted by the Fresnel lens layer (130).
