Claim 0:
1. A compound prism module, comprising:
a first prism, having a first light-incident surface, a first reflecting surface, and a first light-emitting surface connected to each other, wherein the first light-incident surface and the first light-emitting surface are connected to a first side edge, and the first light-incident surface and the first reflecting surface are connected to a first chamfered plane, the first reflecting surface is bonded with an interface filling medium;
a second prism, having a second light-incident surface, a second reflecting surface, and a second light-emitting surface connected to each other, wherein the second light-incident surface and the second light-emitting surface are connected to a second side edge, and the second light-incident surface and the second reflecting surface are connected to a second chamfered plane, the second reflecting surface is bonded with the interface filling medium, wherein the first chamfered plane and the second chamfered plane are attached to each other, so that the first light-incident surface and the second light-incident surface are connected to each other, and the first side edge and the second side edge are parallel to each other and far away from each other; and
the interface filling medium, filled between the first chamfered plane and the second chamfered plane;
wherein the first reflecting surface and the second reflecting surface are provided with reflective coatings to strengthen the reflection effect;
wherein the interface filling medium is an optical adhesive and a refractive index of the optical adhesive after curing is close to a refractive index of the first prism and a refractive index of the second prism.
