Abstract
A light sensing module includes a substrate, a light sensing unit, a first light-transmissive component, and a light shielding layer. The light sensing unit is disposed on the substrate to sense an intensity of a working light beam, and has an upper light receiving surface and a lateral surface perpendicular to the upper light receiving surface. The first light-transmissive component covers the light sensing unit, and has a first refractive index between a refractive index of the light sensing unit and a refractive index of air. The light shielding layer surrounds the lateral surface and is covered by the first light-transmissive component.
