Porro Prims

This Sapphire Porro-Abbe Prism from Meller Optics features a prism configuration and precise prism angles as specified in the sketch. The side faces measure 1.000" +/- 0.005" by 0.500" +/- 0.005", while the hypotenuse face measures 0.707" by 0.500". The prism is made of high-quality, optical-grade sapphire material, with the C-axis ...

Porro prism is a type of reflection prism which can be used to alter the orientation of an image. Light enters the large face of the prism, then hits on the roof, by total internal reflection twice from the roof, the beam exits again through the large face. An image traveling through a Porro prism is rotated by 180deg but not inverted.

Porro Prisms operate on the principle of total internal reflection (TIR). A beam entering perpendicular to the entrance / exit surface is reflected by the two roof surfaces and emerges parallel to itself. For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces cannot be kept sufficiently ...

Did You know?

The history of Porro Prisms dates back to 1854 when Ignazio Porro invented it. It is a type of reflection prism consisting of two prisms in an optical instrument to invert and reverse the orientation of an image by 180 degrees. Porro prisms are used in many optical viewing instruments, such as periscopes, binoculars, and monoculars. They are most often used in pairs, forming a double Porro prism. Double Porro prism systems are used in small optical telescopes to re-orient an inverted image. In many binoculars they both erect the image and provide a longer folded distance between the objective lenses and the eyepieces. The major difference between a roof prism and a Porro prism is that for the roof prism the roof edge is coplanar with the entrance and exit beam, while for a Porro prism the roof edge is orthogonal to the plane formed by the beams.
