Pentagonal prism
Pentagonal prism is one of the fixed-angle (90 °) beam redirectors. It has two purposes: one is that regardless of the incident angle on the first surface, the emergent light turns the incident light to a certain angle (90 °); the second is that it is different from a right-angle prism in that the resulting image is There is no specular reflection in rotation. Pentagonal prisms are commonly used in camera viewfinders, image observation systems, or measuring instruments.
