Description

Corner protector for corner of pyramid prism

Technical Field

The utility model relates to the technical field of corner cube prism protection, in particular to a corner cube prism corner protection device.

Background

Corner cube prisms are also known as retroreflective prisms or trihedral prisms. In the corner cube prism, three reflecting surfaces are perpendicular to each other, just like the side walls of the corner cube. The input surface is perpendicular to the cube diagonal. Ignoring the angle of incidence, the output beam is parallel to the input beam, but in the opposite direction. For better matching, the insertion angles of several angular prisms are typically hexagonal. In the case of such prisms, the phenomenon of total internal reflection occurs, so that it is (possibly) not necessary to apply a specular coating on the reflecting surface. Typically, the reflective surface is an aluminum reflective coating, which is then covered with copper and black paint.

The protective structure of the existing pyramid prism is simple, so that the surface of the pyramid prism is easily abraded due to impact and vibration in the moving process or the transportation process, and the problem of subsequent use is influenced due to the fact that the product quality is reduced.

To the above-mentioned problem, a pyramid prism corner protector is now designed.
