Optical glass Penta Prisms

The penta Prism is one of the redirectors of the fixed angle (90°) of the beam. It has two purposes: one is that no matter what the angle of incidence on the first surface is, the emitted light turns the incident light to a certain angle (90°);  Unlike a Right Angle Prism, the resulting image has neither rotation nor specular reflection. Penta Prisms are often used in camera viewfinders, image observation systems or measuring instruments.
