Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request.

Corner Cube Retroreflectors


Corner Cube Prism is also called Retroreflector or Trihedral Prism. In the Corner Cube Prism, three reflecting surfaces are perpendicular to each other, like the side wall of the cube. The input surface is perpendicular to the cube diagonal. Disregarding the angle of incidence, the output beam is parallel to the input one, but it is of opposite direction. Inset of the several corner prisms, for better matching, their entrance-exit surface is often hexagonal. In case of this prism the phenomenon of full internal reflection occurs so it is not necessary, (however it is possible) to put mirror coating on the reflecting faces. Normally the reflection surfaces are Al reflection coating, and then covered with Cu and Black Painting.

Porro Prism A refracting optical prism used in optical instruments to modify image orientation, In use, the light enters through the largest rectangular plane in the prism, passes through two total reflections of the inclined plane, and then penetrates the original plane of incidence, Because the light comes in and out normally, the prism does not disperse. But the image that passes through Porro prism will be flipped 180 degrees, and it will travel in the direction it entered, which means it will travel 180 degrees.
