Compound prism module and image acquisition module

A compound prism module, comprising:

• a first prism, comprising a first light-incident surface, a first reflecting surface, and a first light-emergent surface connected to each other, wherein the first light-incident surface and the first light-emergent surface are connected to each other on a first side edge;
• and
• a second prism, comprising a second light-incident surface, a second reflecting surface, and a second light-emergent surface connected to each other, wherein the second light-incident surface and the second light-emergent surface are connected to each other on a second side edge, and
• the first prism and the second prism are integrally formed, the first light-incident surface and the second light-incident surface are connected to each other and are coplanar, the first reflecting surface and the second reflecting surface are connected to each other on a third side edge, there is a spacing between the third side edge and a connection between the first light-incident surface and the second light-incident surface, and the first side edge and the second side edge are parallel to each other and far away from each other.
