Summary:A special type light cone with the surface being coated with a nano-film mainly comprises a cone body, a large end and a small end, wherein surfaces of the large end and the small end are coated with a broadband antireflection nano-film of which the wave band being 300-2000 nm and the thickness ranging from 50 nm to 500 nm, and a conical surface of the solid cone body is coated with a SiO2/ZrO2 film system high-reflectivity nano-film of which the thickness ranging from 100 nm to 1000 nm. The light cone provided by the present invention is made of ordinary crown glass. The special type light cone has the advantages of being simple in structure, easy to manufacture, high in coupling efficiency and low in cost, and is applicable to occasions such as light beam reception and light beam coupling and sensing.
