Right Angle Optical Prism

Create rainbows through light refraction. The triangle light crystal prism – put it in the sunlight and watch the principles of refraction at work. A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular.
