Paul prism, also known as Porro prism,is a refractive three prism used in optical instruments to modify image orientation.
The Paul prism is an isosceles right angle three prism made of glass blocks and ends at a right angle.
Paul prisms are most often used in pairs as a combination of two Paul prisms, the second being rotated 90 ° relative to the first.
The net effect of the prism system is that the incident light is changed parallel to the direction of travel, the image is rotated 180 ° and the chirality remains unchanged.
