The invention discloses a composite prism, a compound eye relay assembly and an optical system. The composite prism comprises a prism which is provided with an incident plane and a reflecting plane which is obliquely arranged relative to the incident plane; the first lens is provided with a first transmission plane and an incident curved surface which are oppositely arranged; the first lens is fixed on the incident plane, the first transmission plane faces the incident plane, the incident curved surface is located on an incident light path of the reflection plane, and the incident curved surface is a curved surface protruding outwards; the first lens has positive focal power. According to the invention, light beam convergence and deflection in the light path direction can be realized, the size of the composite prism along the light path direction can be reduced, the volume is reduced, and the cost is reduced. Therefore, when the composite prism is applied to the PGU, the size of the PGU in the height direction of the PGU can be remarkably reduced, and the PGU can be matched with the height of a corresponding installation space in an automobile.

    本申请公开了一种复合棱镜、复眼中继组件、光学系统。该复合棱镜包括:棱镜,具有入射平面以及相对入射平面倾斜设置的反射平面;以及第一透镜,具有相对设置的第一透射平面和入射曲面;第一透镜固定于入射平面且第一透射平面朝向入射平面,入射曲面位于反射平面的入射光路上,且入射曲面为向外凸起的曲面;其中,第一透镜具有正光焦度。本申请不仅可以实现光束的汇聚和光路方向的偏转,而且还可以缩小复合棱镜沿光路方向的尺寸,减小其体积,降低成本。由此,本申请的复合棱镜应用于PGU时能够显著减小PGU沿其高度方向的尺寸,使其能够与汽车内对应的安装空间的高度相适配。
