ABSTRACT:
An elongated X-shaped prism comprising an X-shaped combination of four transparent plates and one central rectangular solid block member. The four transparent plates are disposed in an X-shaped state and each has one side edge adhered to a corresponding side-face of the central member, the width of each side-face of the central member being equal to thickness of each of the four transparent plates. The central member has a refraction index which is higher than the refraction index of the transparent plates. One side surface of the transparent plates is coated with an optical layer.
