Penta Angle Prism
A penta angle prism is a pentagonal prism with four polished faces, two surfaces are reflective and the other two are incident and exit surfaces. The reflector surface of the pentagonal prism is plated with reflective film and protected by black paint. The penta angle prism can turn the light 90° but has neither image plane rotation nor mirror reflection, and the 90° turn will not change because of the different position of the prism, so it is very conducive to assembly. Pentagonal prism is widely used in level and rangefinder, and can also be used in SLR cameras
