DescriptionTwo right-angle prisms are set one above the other with their hypotenuse faces perpendicular to each other. The two prisms are held between two square glass windows.
The assembly is held in a rectangular, blackened brass frame. Each side is open so that light reflected off the prisms will be split to go left or right. The frame has holes for screws.
